Here are my pics from the collection you sent, which if I’m not mistaken, is from this same observation:


Feel free to add them here, but just put my name in the “Copyright Holder” space.

Yep, looks like Hypholoma marginatum

The spores are the right size, the chrysoplurocystidia are abundant, and the cheilocystidia are about the right fusoid or fusoid-ventricose shape, not to mention macro characteristics and habitat. Also, the chrysocystidia fluoresce really brightly, especially in blue light. (I’ll get some micro images tomorrow and make them available shortly.)

I keyed it against Smith’s monograph, as well as Watling & Gregory, plus Bryan Little’s unpublished California monograph, and it keys out in all of these.

Thanks for sending these. I rarely see this species in the SF Bay Area (though it turns up here on occasion), so it was nice to familiarize myself with it.

Could you send these?

Could you send a sample of these? I’d like to scope them, and maybe get a sequence. If you could email me, that would be great. My email is pgwerner (at) sonic(dot)net.

Great find! I can imagine plenty of eyes not recognizing those as psilocybe at a glance…
