NOT Hericium abietis

4 April 2019 UPDATE:

These are unmistakably Hericium erinaceus that were grown from a commercial liquid culture misidentified as Hericium abietis. There is no question about that identification; especially as they have begun putting on teeth and slicing one opened revealed a solid interior. At least now I know why I’ve been puzzling over their appearance looking so stubbornly underdeveloped!

For sake of comparison, the first image below is of a correctly identified Hericium abietis photographed at the Mount Pisgah Mushroom Festival at Eugene, Oregon.

The following show what was grown from a commercial culture that was purchased earlier this year. The amazing part is that these mushrooms grew so well on a mixture of douglas-fir, white pine and spruce!

That is very clearly the flesh of an erinaceus not abietis.

That mushroom was delicious in dinner last night. Both the taste and the texture were excellent.

I am amazed at how big these are getting prior to putting on their adult teeth. Those bags are 9 inches (22.95 cm) wide.
The media is a supplemented blend of doug-fir, pine and spruce.

However, the ID of these is presently in question until I start seeing a lot more tooth and branch development.

A recent view of the lion’s mane chamber

A slideshow and talk was recently given to the Mendocino Coast Mushroom Club. It was a lot of fun that included meeting a bunch of really nice mushroom people!

I had hoped to load that slideshow to the website but encountered some technical difficulties. It was instead turned into a ~157mb PDF that can be accessed HERE. The only slide that did not import was the video above.

Lion’s manes are back!

The first harvest of a few lion’s manes occurred this week. Unsurprisingly they all sold at yesterday’s market. More are on the way for this Saturday’s Farmers Market and for next week.

August update

We decided to take advantage of the hot weather for pressure washing the entire facility. We will be back at the Farmer’s Markets in early September.

Another great week.

This week saw a total harvest of 21 pounds of lion’s manes and a much smaller amount of shiitakes. Our mushrooms have been selling out the past couple of weeks so we will keep expanding our production to fulfill the growing demand.

We hope to see you at the Ft. Bragg, Mendocino or Ukiah certified Farmers Market.

See you at the Farmer’s Market.

Lion’s mane harvests are still on the light side (4 kg were harvested from the two trays shown fruiting in the previous video) but despite that they made some people in Mendocino happy last week (and a couple in Ukiah). A light offering of our mushrooms will be at Ft. Bragg today and more at Ukiah on Saturday; with lots more to come and another round of bags scheduled to be opened and added today. We will also be at Mendocino next week.

Another week of mushroom growth; shown on Tuesday afternoon..

 

AND, while the next shiitakes to be harvested from our spawn bag production are still some weeks in the future, the first few shiitakes are beginning on some of the ricks that were plugged last summer.

Spring in 2018

We are looking forward to the 2018 Farmer’s Market season!
This year we will be sharing mushrooms with The Forest People so we will be offering each other’s mushrooms; our lion’s manes and their oysters respectively. One or both of us hopes to see you in Mendocino, Ft. Bragg or Ukiah at the MCFarm certified farmers market.
A look at the Hericium fruiting chamber today is below. It appears that we will be back at a steady pace again within the next two weeks.

These are ready to harvest.

 

The garden is gearing up for Spring also.

We will soon have gobo (burdock root) and will be bringing some incredible ha gobo leaves to the next farmer’s market. This has become one of our favorite greens. It has a flavor similar to collards but with a luscious velvety mouth feel.

New life in 2018

After resolving a technical problem with our ISP, all of our web content and email occurring since the 26th of last July has vanished.

Some views of the Hericium fruiting chamber are below; taking us up to the point of a fungus gnat invasion in January. We shut down following that discovery (look for discolored or prematurely toothy fruiting bodies to see its beginning), decontaminated the entire facility, built another layer of entryway protection and are now in the process of refilling the chamber with bags again for 2018 Farmers Market.
New videos will be added soon showing our progress but for now here are some looks at our experience occurring between late July 2017 and January 2018.

We look forward to seeing you at the Boonville Farmer’s Market.

 

Another great year!

2017 promises to be an exiting year.  We hope to see you at the Boonville Farmer’s Market.

As of February 25, 2017, we can now accept payments using credit cards or PayPal at the Farmer’s Market.

We made a small harvest for market in between these two sets of images but thought it would be of interest to see some paired images from 30 September and 1 October as they show how fast lion’s manes can grow.

Amazing Mushrooms!by Natural Products of Boonville

We look forward to seeing you at this week’s Farmer’s Market.

We will have lots of lion’s manes, a few Hericium americanum and shiitakes.
Also some potatoes for your planting delight.

 

19 November 2015

It is actually the 4th of December and I had hoped to post this pair of youtube videos a few days ago so am editing an older post.

The first view was following a harvest and the beginning of another round of open bags. Some from the previous round are still going and on their second flush.

 

 

This was the view on 24 November.

 

There is another video at youtube that was taken in between those. The camera had become lost and does not reliably date media so the day it was taken is unclear but was likely on the 21st or 22nd of November.

We can’t sell wild mushrooms but we certainly do eat them! Part of this one was delicious last night cooked with chicken and vegetables.

And there was another Lion’s mane that was found today (2 November). Harvesting mushrooms such as this one can be potentially dangerous.

Hericium-erinaceus-2nov2015

I did not manage to bring this one down as a single, 791 gram, piece.

There was another one above it that was easily 30+ feet higher on the tree (so it was safe from me).

A Chinese adage is good to keep in mind considering Hericium erinaceus eats trees:
Fools and smoke like to climb high

This is that same tree when I checked it a month ago (5 October)

Getting back into gear

Things are moving along well as we begin refilling the Hericium fruiting chamber.

These images are from 22 October 2015.

We just completed a nice harvest, removed those trays and replaced them with the spawn bags that are ready. We hope to see you at this weekend’s Farmer’s Market.
It will be the second to last certified Farmer’s Market of the season.

What is in our mushrooms?

1 lb of shiitake

What goes into our mushrooms is really simple.

We start with tan-oak (Lithocarpus densifolia) sawdust from the local business Frank’s Firewood.
Frank is in the business of producing and selling firewood but that process creates a lot of great sawdust which is perfect for our needs. Frank refuses to take in any trees that have been killed or treated with herbicides.

Frank's Firewood sawdust from Frank's Firewood sawdust from Frank's Firewood

sawdust
To that is added organic wheat bran and the highest-quality pure gypsum that is considered to be ‘organic’. We are not presently recognized as organic producers but do our best to include only pure ingredients.

When we make spawn, we use organic rye grain. If we order commercial grain spawn it comes from a certified organic producer.

rye

The only other thing that we incorporate in the recipe for our mushroom growing media is the high-quality water from our protected well.

We are taking it one step farther and as of late February 2016 will be using only organic nonGMO dextrose which is derived from grapes and imported from Italy thanks to Naturalia Ingredients and Ciranda. There was so much difficulty locating organic dextrose that we have decided to offer small quantities at reasonable prices to other mushroom producers who are wanting to use entirely organic ingredients.

organic nonGMO dextrose

Lion’s mane are delicate and fragile mushrooms that can bruise easily (compare ours to those from other producers). To minimize handling, and any bruising or discoloration, we carefully pick each individual Lion’s manes using a bakery tissue and gently nestle them together loosely. Most mushrooms, such as shiitakes, don’t require that. Whenever possible all of our mushrooms are harvested directly into their resale packaging. Boxes such as the one below promptly go into refrigeration to ensure you of the longest possible shelflife.

The most important thing we put into the production of all of our mushrooms is a lot of love.

That process all went great but for reasons we do not understand recovery is proceeding a little slowly. We had hoped to have the lion’s manes back in action for this week’s Farmer’s Market but it appears they won’t catch up with the interest until midweek next week.

Cooking mushrooms

Downloadable PDF version of this page

Cooking with the Lion’s Mane mushrooms (Hericium species)

There are many ways to cook the Lion’s mane (Hericium) mushrooms.
My favorite two:

1)  Cut into 1/2 inch slices or if solid and very large the slices also get re-sliced into 1/2” wide strips. Some people prefer to tear them into pieces. Try both approaches to discover which you like best.

Wild harvested mushrooms, including Lion’s mane, will usually go into a dry fry pan at the beginning to ‘sweat out’ a lot of liquid (and flavor). which will then take a few minutes to reduce and be re-sorbed back into the mushroom (usually 6-8).
If the hericiums were cultivated, or if they were wild harvested during periods of non-rainy weather, they usually need a few tablespoons of water to be added at first (and occasionally more later) to prevent scorching.
If oil is used it should be only enough to prevent sticking. Too much results in frying the mushroom. Ideally just small bits of water should be used at this point.

The mushrooms should be started on a medium high heat and cooked for around 1-2 minutes with stirring — just to get them completely hot quickly, then the heat should then be reduced to medium low or low and they should be cooked covered for another 15 minutes with occasional stirring. Halfway into the cooking add a small amount of butter or a 2:1 mixture of olive oil and butter.
Wine or other optional liquid seasonings should be added only towards the end of the cooking process or they can be absorbed to the point of obscuring the delicate flavor of the lion’s mane.

2)  Start out the same as above but add the butter and/or oil much sooner, as soon as liquids have been resorbed by the mushrooms. (be sure that all excess liquid has been resorbed before adding butter/oil) and cook over moderate heat until the edges and teeth begin to get golden-brown and crunchy.  This will require  a bit more oil than the first method plus very close monitoring towards the end, to avoid scorching.

All Hericium mushroom species freeze well once cooked. They can be prepared when available, packed into half-pint jars, and frozen for use at another time.

Easy Chicken with Lion’s Mane, peppers & potatoes

Thinly slice or dice a medium onion and a largish clove of garlic.
Lightly cook in a frying pan in oil. I greatly like a blend of Avocado oil and roasted garlic olive oil.
Add 1/2 dozen baby bell peppers cut into quarters.
When the color of the onions and the peppers begins to change, turn over and add 1-3/4# organic boneless chicken thighs, approximately 2 cups of (four medium sized)
potatoes or the equivalent in small potatoes,  roughly same amount of Hericium as potatoes (cut into 1/2 inch sections; or if large the slices should be resliced into 1/2″ wide strips) approximately two cups once chopped. I like to add one or two slices of butter at that point as well.
Cover and cook on medium-low to medium heat until the chicken is done.  Usually 15-20 minutes.
Salt and/or pepper to taste, if needed.
Hot peppers may be added with the bell peppers if heat is desired and the chicken may be omitted if a vegetarian dish is desired.
If the chicken is omitted more monitoring is required and a few tablespoons of water may be needed in order to prevent scorching of the vegetables.

 

Cooking with Shiitake mushroom (Lentinula edodes)

Cook them in good oil such as butter, olive-oil:butter, avocado oil, etcetera until the slices are limp.
Shiitakes are versatile. They can be stir fried, baked plain or stuffed, marinated and grilled, added whole to the vegetables that get cooked along with a roast or in an earthen oven, added to soups, stews or meat dishes, or they can be cooked alone and enjoyed as  dish. Precooked shiitakes can also then be combined with other foods such as omelettes, vegetables, soups and salads. It may be convenient to cook enough mushrooms for adding to 2 or 4 meals.  Cooked shiitakes freeze acceptably.
Butter, garlic & a little salt may compliment shiitakes own distinctive flavor.
Stems of shiitakes are most often fibrous and very tough. They should be removed before cooking.
Thicker stems can be very thinly sliced and fried until golden brown in butter or butter and oil for a crispy-to-chewy treat. Thinner, tougher stems can be dried and ground into a powder for later use as a thickening agent in soups, stews, stock reductions and many types of sauces. Or stems *can* be discarded.

Shiitake ‘bacon’ with sea-palm fronds

Slice shiitakes thin but not too thinly. A couple to several (2-4) mm is fine. Try to slice them evenly.
Place the slices into a bowl and add a minimum amount of your favorite cooking oil then gently stir extremely well. A variant of this is to spread the slices out on a cooking sheet and lightly mist with a light spray of oil before tossing to coat all surfaces. It is important to not use too much oil.
The goal is to get a bare minimum but thorough coating of oil on all of the mushrooms. A special touch can be created by adding a drop of liquid smoke to the oil and shaking very well before oiling the mushrooms.
Once this is done lightly season with sea salt and again mix thoroughly. Other seasonings can also be added but keeping it simple has great results.
Spread the shiitakes out into a single layer on a foil or parchment paper lined baking sheet. Sprinkle the top with coarse sea salt.
Bake in a preheated 350°F oven, checking frequently, especially towards the end.
You want them to cook completely dry, turning brown with some golden parts. This takes a few minutes (15 or more minutes is common; the hotter the oven the faster it goes but monitor them carefully as rotating the pan may be required in some ovens. The last few minutes of this goes very fast so it requires a close eye to prevent burning.
Using care, transfer the baked mushrooms from the hot sheet into a bowl.
Let it cool and you now have a bowl of shiitake bacon.
Break some crunchy dried sea palm fronds into smaller pieces & toss with your shiitake bacon. Enjoy.
If you are an optimist this can be packed into a jar and placed into a refrigerator for storage. If you are a realist you will probably leave it available on the counter knowing it will be consumed very quickly.

Caution: this food item may be found to be compulsively addictive.

It is important to cook shiitakes thoroughly.

Approximately one in 50 or more people appear to have a sensitivity to uncooked or undercooked shiitakes. Most shiitakes consumed in the world are dried and then rehydrated; drying is not the same as cooking and a thorough cooking is still needed.
In those rare individuals who are allergic, consuming undercooked or raw shiitakes may result in a skin rash resembling poison oak but accompanied by characteristic scratch-like lines (“flagellate”). If there is an allergic reaction, the rash begins 24-72 hr following ingestion and can last for up to 14 days. It resolves spontaneously without any treatment but a doctor can shorten its duration.
Most people are not allergic. Thoroughly cooked shiitakes appear to be OK for everyone.

Our shiitakes are finally getting going again!

Shiitakes!

This first small round of bags is showing some signs of heat stress but they are just the beginning. The new fruiting chamber should be able to keep the shiitakes cool enough to stay happy this summer. It just came online within the past few days.

The day before market

Here is a look at a few of the mushrooms that will be going to the Farmer’s Market tomorrow (23 May 2015).

This week the Boonville Farmer’s Market is being held at its regular time from 10-1230 in the Boonville Hotel parking lot followed by a special event at the Madrones in Philo from 1-4.

Three Hericium species will be available this week and the shiitakes are getting closer to fruiting with every passing day.

Hericium americanum (Bear’s head) is winding down. This cycle has been a market-test to see how well people like it so the availability is still limited. If it does well at this weekend’s market I’ll start up another run of it and it will return to production in a few weeks.

The slender roots can reach 4 feet, and resemble a carrot in shape. Harvesting is typically done when they reach around two feet long. The roots are brown with white flesh that rapidly darkens with exposure to air. That oxidation can also stain fingers so latex gloves might be desired.
Preparation is commonly done using a bowl of acidified water to place pieces into as they get cut. This will help keep them light colored.

 

Burdock roots can be eaten raw or cooked. They have a mild, earthy flavor that is highly prized for rich soups and stews. The root of burdock is very commonly julienned or sliced thinly.

 

The immature peeled flower stalks and the young leaves can also be eaten fresh or cooked. Cultivars have been developed specifically for their leaves. The roots are also enjoyed pickled.

 

 

Burdock seeds were the inspiration for the invention of Velcro by George de Mestral in the 1940s.

Physalis peruviana

 

 

Golden berry (Physalis peruviana)
golden-berry

All plant parts of the golden-berry other than ripe fruit, including the unripe fruit, are considered to be poisonous. The fruit are harvested after their husks have fallen to the ground, but care is needed to be sure that they have turned golden-yellow and are fully ripe. Mature fruit will keep for several months.
The ripe fruit can be eaten fresh out of hand or used in salads and cooked dishes. They are also popular dipped in chocolate or candied or dried into golden “raisins”.

English: pichuberries (USA), Cape gooseberry (South Africa, UK), African ground cherry, Aztec berry, Barbados gooseberry, bladderberry, giant ground cherry, Goldenberry, golden berry,  golden Cape gooseberry, golden husk goldenberry, gooseberry tomato, ground cherry, ground-cherry, groundcherry, Husk Cherry, Inca berry,  love apple, Peruvian cherry, Peruvian groundcherry, Peruvian Ground Cherry, Peruvian cherry, Peruvian tomato, Poha, Poha Berry, strawberry tomato, wild gooseberry, winter cherry. (Not related to any true cherry or true gooseberry.)
French: amour en cage
Italian: alchechengi.
Spanish: uchuva (Colombia)

This plant is originally from Brazil but has become naturalized in Peru and Chile.
It has been cultivated in England and South Africa for more than 200 years. It has become distributed almost worldwide and is regarded to be an invasive pest in frost-free climates such as Hawaii.
It is cultivated in many of the African nations, also in Turkey, India, Australia, New Zealand, Ecuador, Venezuela, Colombia, Chile, and Peru.

It was reported to be potentially harmful to the heart health of men if they consume massive quantities of the fruit (>5 kg of fruit per kg of body weight). This does not appear to pose a significant risk factor as people always ingest far less.

Plugging Logs

Plugging logs is nowhere near as efficient as growing mushrooms using spawn bags but it is within more people’s reach. Logs also have an advantage of lasting longer so make a nice complement to our bag production.

Holes are best drilled using a high-speed drill and a stop.

There are a couple of different tools for this.

Shiitake drill (10,000 rpm)

high-speed shiitake drill

high-speed shiitake drill

The Hitachi Koki DW12SA (S) is a specialty tool that was made by Hitachi for the shiitake industry.

It can sometimes be difficult to obtain outside of Japan but Japanese people can help obtain one by serving as a reshipper. A number of people do this as a commercial service. Acquiring it can cost about the same as the price of the drill once factoring in all of the postage. SOMETIMES companies exist which resell this item so it is worth checking if anyone is presently doing this.

 

High-speed modified drill

high-speed drill using angle grinder

high-speed drill using angle grinder

An angle grinder (10,000 rpm) can be obtained from any hardware store.

An angle adaptor and a drill bit with a stop can be obtained from Field and Forest that will turn it into a high-speed shiitake drill.

That same company also sells this as a complete set including the angle grinder.

This costs in the ball park of the price for the shiitake drill in Japan.

Tools & supplies:

high-speed drill 

bit with stop sized for media choice (the shiitake drill has a built-in stop; drill bits that include stops are convenient). 12mm for sawdust media. 10.5mm for plugs.

inoculation tool for sawdust or a hammer for plugs.

bowl or container to hold sawdust media or plugs while working

wax dauber

wax pot

hot plate

eye protection

gloves

metal plant tags

writing implement

Hericium ptychogasteroides

Hericium ptychogasteroides

[Given as accepted species in Index Species Fungorum. Molecular work not located.]

“? Quercus” “on dead wood” CABI Index of Fungi 2: 311 citing Nikolaeva 1956 Bot. Zh. SSSR 41: 999 (Primorsky Krai in far eastern Russia; Maritime Territory 45.000000°; 135.000000°).

Name means “resembling a folded stomach”. 

Unable to access the original description.  From the Red Book of Russia Plants at Mycology.su:
Fruit body resembled a pincushion.
Teeth covering almost entire surface of fruiting body.
Basidia and basidiospores absent.

Maas Geesteranus made a helpful comment: “In the description, […] Nikolaeva stated that her species is based on an imperfect, i.e. conidiabearing, state. It is difficult, if possible at all, to ascertain to which species the corresponding perfect state would belong, but with Boudier’s plate in mind, H. ptychogasteroides may possibly be thought of as the conidial state of H. erinaceus.”

Stalpers 1996 suggested this name was a “nomen dubium, cf. Hericium erinaceus Bull.” [Nikolajeva, 1956, Botaniceskij zurnal SSSR, 41: 999, LEG] 

Does not appear to have been reported a second time.

Hericium fimbriatum

Hericium fimbriatum
[Given as an accepted species in Index Species Fungorum but most authorities reject. Molecular work not located.]

Considering Banker’s description, the very un-Hericium-like spores, plus his comparison of this to H. crocea (= Sarcodontia crocea); Meruliaceae), the acceptance of this as a valid name seems worth questioning.

ISF also mentions Saccardo 1912 Sylloge Fungorum 21: 373 as a corroborating reference but Saccardo is essentially just repeating Banker 1906 in Latin.

“On a decaying stump of some hard wood, between the bark and the wood.” Banker 1906 (Penn-sylvania, USA).

 

Hericium erinaceus ssp. erinaceo-abietis

Hericium erinaceus ssp. erinaceo-abietis

[This name appeared as Hericium erinaceum ssp. erinaceo-abietis.]

Quercus sp. Live tree. Burdsall et alia 1978 (Virginia, USA).

Burdsall’s reasoning:

1) “Hericium erinaceum has large ovoid basidiocarps with densely crowded pendent teeth up to 3 cm long and H. abietis basidiocarps are loosely organized systems of branches with less crowded pendent teeth. Hericium erinaceum subsp. erinaceo-abietis, on the other hand, is an irregularly shaped, solid, nodulose mass with small teeth (up to 3 mm long) covering the entire surface and protruding in all directions.”

2) “The basidiospores of H. abietis are 5-6 x 4-5 μm while those of H. erinaceum subsp. erinaceo-abietis are 6-7.5 x 4.5-6 μm.”

3) “The two also differ in structure of tooth trama.” 

4) “Hericium erinaceum subsp. erinaceo-abietis lacks the broad (up to 15 μm diam) thick-walled hyphae (walls up to 5 μm thick) which are found in H. erinaceum and the inflated cells (up to 15 μm diam) that have little wall thickening.” 

4) “In culture, H. erinaceum subsp. erinaceo-abietis grows about half as fast as H. erinaceum on malt extract agar at 25 C and about twice as fast at 32 C.” 

5) “The new subspecies and H. abietis grow equally well at 25 C on malt extract agar but H. abietis does not grow at 32 C while the new subspecies does.”

6) “The pairings between OKM 15159 single spore isolates and those of H. erinaceum [from Maryland (OKM 4950) and Arizona (JPL 317)] were totally compatible. Similar pairings between OKM 15159 single spore isolates and those from three different collections of H. abietis (a species found only in the northwestern U.S. and western Canada), however, showed partial, but not complete, compatibility as expressed by clamp connection formation.”

Maas Geestereanus’ comment concerning H. ptychogasteroides being the immature conidial state of erinaceus may be pertinent in regard to this? 

Yellowish is a normal aging color, becoming beige in its final stages of decline and collapse; orange to brown commonly occurs from oxidizing in old age or drying. Chocolate brown or grey indicates an unsuccessful battle with a contaminant. Pink or salmon are colorations that can occur under some conditions of warm temperatures or excess moisture. With sun, heat and dryness it can even become decidedly reddish. These are most often surface colors and reveal a white interior. 

Salmon, yellow, and pink can also occasionally be seen in young cultivated H. erinaceus and is not at all uncommon in young H. americanum. It is most often outgrown by the time that the teeth develop. Excess moisture stimulates its appearance in cultivation.

This color also can occur in the wild. For example the salmon-pink lion’s mane, probably also H. americanum, at Chris Mabberly’s website given as a coralloides.

It tends to be the most noticeable before the teeth have fully developed which not uncommonly looks very much like the photograph in Burdsall. Due to the coloration, the spore size and the growth form, Burdsall’s fungus was very likely an immature  americanum.

“In the late 1970’s a new taxon was described, i.e., Hericium erinaceum subsp. erinaceo abietis. This taxon differed from the typical H. erinaceum, e.g., by morphological traits of the fruitbody, spore size and mycelium growth rate. Studies showed that the described subspecies was a sterile hybrid between H. erinaceum and H. abietis [19].”

Sokół et al 2016.

It is worth questioning that conclusion. How such a mating of H. erinaceus with a species that is restricted to the Pacific North-West would have occurred in the first place has its own hurdles. The progeny then being found on a tree in Virginia?  It is worth looking closer.

Ginns appeared to add some support but he actually stopped two important steps short of actually evaluating the matter. His words on the matter are noteworthy: “Further, subsp. erinaceoabietis was compatible with H. abietis (No. 46) and H. erinaceus (No. 34) but was not tested against H. americanum or H. coralloides.” [Boldface added.]

It is this author’s suspicion that Ginns might have found compatibility had he tested it with americanum.

Most peculiar with regards to the claim of this being a hybrid is that Burdsall had actually dismissed that idea since he could not produce clamp formations with using single spore isolates of the two putative parent species. His comments: “The possibility that OKM 15159 was a hybrid of H. erinaceum x H. abietis was considered but in no case were clamp connections formed when single spore isolates of these two species were paired.” 

It is worth adding that IF H. erinaceum and H. abietis could be hybridized, the use of mating experiments for identifying the Hericium species would seem to be conceptually invalid.

There has been no confirmatory find reported.

Hericium erinaceum

This name, “Hericium erinaceum”, is a misspelling.

Many culture banks, herbarium data-bases, the National Checklist of Taiwan, the Atlas of Living Australia, a number of patents, assorted publications in analytical, medical &/or nutritional research and even a few mycologists employ the name “Hericium erinaceum (Bull. : Fr.) Pers.” Sometimes this name has appeared in molecular work alongside H. erinaceus. Sometimes it is given as the accepted name. It is however an error that now comprises a substantial minority of the locatable instances of use.

The name being misspelled “erinaceum” originated in the literature as a typo made in Persoon’s 1818 Traite sur les Champignons Comestibles (on page 251). 

Persoon had earlier employed the spelling erinaceus in 1794 (in Roemer’s Neues Magazin für die Botanik, page 153); also in 1797 (Commentatio de Fungis Clavaeformibus, page 27), and in 1801 (Synopsis Methodica Fungorum, page 560) and he did so again later in 1825 (Mycologia Europaea, volume 2, page 153). 

1818 was the only instance in any of Persoon’s works using the spelling erinaceum. Due to his respected stature as an authority and the nature of the work that it appeared within, his error has achieved some lasting power through its retellings.

Persoon’s 1818 entry itself supports his spelling as erinaceum being made in error. In this book, all of the authorities included by Persoon had spelled it erinaceus. Persoon had cited Bulliard 1797 (see page 304 and plate 34), Paulet 1793 (see plate CXCIII) and Trattinnick 1805 (see page 191). Persoon 1818 may have been the first appearance of the error but sadly this spelling was picked up by a minor portion of active authors from that time period onward.

Due to a minor number of prominent workers across several disciplines missing or not questioning the error, with some perhaps regarding it to be a correction of gender by Persoon, today a Google search will reveal erinaceus : erinaceum are currently both in use at a 28:1 ratio, with respectively 948,000 vs 33,800 results. In some of the latter instances both names are presented to be synonyms but “erinaceum” is actually quite easy to find used in the analytical and pharmacological literature. The GBIF database shows erinaceum with 39 entries and erinaceus with 1559. It is especially common in Asian publications and databases; possibly due to databases such as the Lai 2012, Atlas of Living Australia and Cybertruffle presenting it as the accepted name for the species.

In some instances erinaceum and erinaceus have even been evaluated in studies as separate taxa.

Serendipitously, Park et alia 2014 compared specimens bearing both names in a molecular study and reported differences between Asian erinaceum and US erinaceus.

More work is clearly in order but the application of Latin binomials does have some clearly defined rules.

Despite that there is a peculiar hurdle in this instance. The origin of the problem arose from a leading authority, Persoon, putting a misspelling into print and this error then being repeated by a few other respected authorities. That is an unfortunate combination that creates long-lasting perpetuations which are often highly resistant to correction.

Competent mycologists are included among those who have used, and in a few cases still use, the name. While Cooke 1871 used erinaceus, his successors, Stevenson 1886 and Massee 1892 changed it to erinaceum. In 1978, Burdsall et alia (Mycotaxon, 7(1): 1–9) attempted to describe a mushroom they encountered as new taxa Hericium erinaceum ssp. erinaceo-abietis.

Burdsall commented that Harrison 1973 (Michigan Botanist, 12: 177–194) had recognized Hericium erinaceum as one of the accepted Hericium species. Harrison had actually used the spelling erinaceus and never mentioned erinaceum. 

Some of the resistance to correction may involve workers trying to match genders of the suffixes without understanding why the word choices are what they are. Misperceptions of erinaceum as a correction of the gender no doubt helped perpetuate it.

Henderson 1981 helpfully made the comment that “”hedgehog” has the masculine ending “-us” even though Hericium is neuter, because “erinaceus” is a noun rather than an adjective.” 

Erinaceus europaeus is the European hedgehog. 

[In Latin, the nominative form of the noun is erinaceus and erinaceum is the accusative form.]

Many authorities and databases, have noted erinaceum to be an orthographic variant (i.e. a name with a spelling that entered the literature as a typo or other mistake). 

Fortunately the International Code of Nomenclature for Algae, Fungi, and Plants (currently the Shenzhen Code 2018 — Turland et alia (eds.) 2018) includes some clear and simple provisions for what taxonomy is supposed to do with such orthographic variants:

 61.1. Only one orthographical variant of any one name is treated as validly published: the form that appears in the original publication […] [See the Code for the acceptable exceptions to this rule.]

 61.4. The orthographical variants of a name are to be corrected to the validly published form of that name. Whenever such a variant appears in a publication, it is to be treated as if it appeared in its corrected form

If only reality worked so simply…

The most common host genus [in Scandinavia] is Betula (64.3%) [Norway 30%; central & northern Sweden 41.8% and Finland 75.2%], followed by Populus, predominately tremula, (18.1%) [Norway 40%; Sweden 23.6% and Finland 14.5%];
“In Denmark the commonest host tree is Fagus sylvatica, and only one find from Betula was reported by Knudsen and Pedersen (1984). The Norwegian hosts were Betula sp., Populus tremula and Sorbus aucuparia, in this order. In [southern] Sweden, 21.8% of the collections derived from Fagus sylvatica;
Collections also exist from Acer platanoides, Alnus sp., Populus tremula, Ulmus sp., Salix sp. and Tilia cordata. In two Swedish collections, Abies was indicated as the host, but samples of the wood were lacking and it was impossible to confirm the determination; these collections also represented H. coralloides in the present sense.” (Sweden);
Additional Scandinavian collections were reported on Acer platanoides, Alnus incana & Alnus glutinosa, Betula pubescens & Betula pendula, Populus balsamifera, Salix spp, Tilia cordata & Ulmus sp.;
These records indicate that in northwestern Europe H. coralloides grows almost exclusively on hardwoods;
“In Central Europe H. coralloides favours Fagus sylvatica, but has also been reported from the genera Betula, Carpinus, Corylus, Fraxinus, Juglans, Morus, Pyrus, Quercus and Ulmus.”

ALA (Lists 67 records from New Zealand; the vast majority as Hericium clathroides. Plus 8 additional records of the same as Hericium sp.). 

The reports from New Zealand and Australia need more study to establish if they represent one or two species. The very slender branched and long toothed specimens are quite striking by comparison to the rest. 

Colenso 1889 attempted to propose Hydnum novae-zealandiae as a new species; commenting that it was different in form from a single Hydnum laciniatum he had encountered some 40 years earlier. His newer specimen was collected from a Beilschmiedia tawa; which is not uncommonly represented as a host tree in the coralloides/laciniatum collections that are detailed at ALA. He included no illustration but his account is interesting in view of the other collection reports. Colenso considered these to be rare in New Zealand. It might be wondered if the increase of reports in subsequent years was more heavily affected by the impact of New Zealand’s logging industry or the increased frequency of nature-minded forest visitors due to tourism OR if Colenso’s difficulty in finding more specimens in the 19th century  perhaps reflected the Maori’s known enjoyment of the fungus as food?

[Given as accepted species in Index Species Fungorum. Most workers consider this to be a synonym for coralloides. Some (such as Thongbai et alia 2015) reserve clathroides for a New Zealand find that is most often housed in Australian herbariums as coralloides, or some workers (such as Maas Geesteranus) limit coralloides to being a conifer lover, and ignore the reports of hardwood loving coralloides in North America, Asia, Australia, NZ and Europe. Some recognize clathroides AND coralloides. Additional confusions between alpestre and coralloides may also exist.]

Atlas of Living Australia lists: 

39 records from NSW, Australia; many of which were submitted as H. clathroides;

34 records from Queensland, Australia; many submitted as H. clathroides;

56 records from Victoria, Australia; many submitted as H. clathroides;

67 records from New Zealand; the vast majority as Hericium clathroides. (There are 8 additional records as Hericium sp.). 

The majority of those were on hardwoods but that is not true for all of them.

Hericium botryoides

Hericium botryoides 

[Given as accepted species in Index Species Fungorum. I have not yet located any molecular work .]

Quercus myrsinaefolia (Chinese evergreen oak) On living trunks (“Ad truncos vivos.”) by Ito & Otani, in Otani 1957 (Japan).

This was presented to be a new species based on: 

1) Different habitat: on a live tree of this species; whereas H. erinaceus was said to fruit on dead trunks of other Quercus species and Castanopsis cuspidata.

2) Having a salmon-pink or light yellowish-orange color with yellow flesh; rather than “whitish, then yellowish” with white flesh in H. erinaceus.

3) Having a botyroidal growth form. “Compound tubercular mass 18×13 cm” compared to H. erinaceus’s “Simple tubercular mass 5–30 cm diam.”

4) Having shorter subulate spines., 5—10 mm long arranged all of the surface; H. erinaceus was said to have 10—60 mm long straight spines hanging downward and no spines on the upper surface.

5) Gloeocystidia cylindrical with capitate apex; gloeocystidia of H. erinaceus cylindrical or fusoid, not capitate.

 6) Spores subglobose or ovoid 4.5–6.5 x 4.5–6 µm; compared to H. erinaceus having globose or ovoid 5.5–7 µm spores. 

7) This taxa has also been commented upon for significance of having non-amyloid (hyaline to slightly flesh-colored) spores reported but it is also noteworthy that, in this same paper, Hericium erinaceus was similarly reported to show a hyaline reaction (non-amyloid) for its spores. AND it is also noteworthy that other workers have claimed a hyaline reaction for erinaceus spores (for example BCRC lists a hyaline reaction both for H. erinaceus and also for “H. ramosum”) suggesting there may be divergent approaches to staining or a possible misinterpretation of colors based on cultural color definitions?

Only point 5 is actually potentially significant as H. erinaceus can apparently share all of the other features.

Ito and Otani’s fungus seems most likely to be an immature H. erinaceus colored by adverse conditions of moisture and/or temperature. 

Compare to Burdsall’s “Hericium erinaceum ssp. erinaceo-abietis”, or to Nikolaeva’s Hericium pytchogasteroides, or to our notes concerning an odd erinaceus encountered in Mendocino County. The latter has subglobose to ovoid spores up to 5.25 x 7 µm.

Hericium botyroides does not appear to have ever been collected a second time.

“On beech and hickory logs” Banker 1906 (as H. coralloides).

“On wood, especially of Carya and Fagus spp” USDA ARS GRIN (eastern North America).

“old logs, dead stubs, or cankers on living trees with heart rot. It has been reported on Fagus, Acer, Carya and Quercus. Collections usually recorded as occurring on rotting deciduous logs. In Michigan, most commonly reported on Acer spp., but Fagus is the most common host over its entire range. Populus has been considered a common substrate, but oddly enough, there are no collections on this host in the University of Michigan Herbarium. The species is limited in North America to east of the Great Plains, and north of North Carolina and Tennessee.”
 Harrison 1973 (as Hericium coralloides).
[Carya is hickory which some commercial growers have reported won’t support Hericium growth in cultivation.]

“Saprobic and possibly parasitic; […] fruiting on dead hardwood logs and stumps, or from the wounds of living hardwoods; documented to fruit (rarely) on conifer wood;” Kuo website.

“growing on hardwoods” “on wood of hardwoods and conifers” Henderson 1981.

“white rot on the logs and standing trunks of hardwoods and conifers” Glaeser & Smith 2013 citing Binion et alia 2008. This reference to conifers may have involved confusion with abietis but those of Ginns 1985 and also Stalpers 1992, both reporting it on Tsuga in New York, clearly do not.

“[…] all Canadian cultures labelled H. erinaceus were reassigned to H. americanum. The presence of H. erinaceus in Canada could not be confirmed.” Ginns 1985. Ginns DID keep the name erinaceus for many collections from the USA.

In our cultivation of this species, Hericium americanum did great on Notholithocarpus densiflorus (tan-oak) sawdust media, and in liquid culture, but the mycelium would not grow at all on big-leaf maple (Acer macrophyllum) even when the logs were very heavily plugged.
