Hi Rich,

you’re correct to call this C. croceus, although that having observed
them again and again our Spring Sierran Dermocybe form strange group
that needs more analysis. I have shared these thoughts with Joe
Ammirati who wrote the Dermocybe chapter in North America. Check
carefully and tell if you do not see a actually dark purplish-black
color under KOH. I used to see brown, but now I see a purplish tint. I
was just about to ask for the KOH reaction and I saw you having posted
it — very nice!!
