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.
