A. pilosporus Peck

A. bernardii normally has a much stronger rufescent reaction: deep-orange-red flesh throughout, after exposure. Also, the briney odor should be stronger than “somewhat”. This material, based on images and comments, is a good fit for A. pilosporus Peck, a very rare species with a mild briney odor from Colorado, Pennsylvania, Spain, and probably (rarely) elsewhere. Careful spore measurement will help make the call: A. pilosporus spores are 8-10% longer and broader.

A. bitorquis is sometimes pink here and there like this collection, but should never have a briney odor. A. vinaceovirens never turns pinkish and has an offensive musty-briney odor.

I’ve collected all of the above and sequenced all but A. vinaceovirens. A. pilosporus was not recorded from anywhere between 1903 and 2002.

If the collection still exists or if another is found it would be noble to put it into a herbarium such as SFSU.

I hear this one is a good edible, altho I have never eaten it. It is also common in grass at the San Leandro Marina.

I’d certainly wager Agaricus, at the least.

The cap looks deformed, as if it were trying to grow up under hemlock or other strong roots.
