ITS matches holotype, as well as macro and micro characters. Dave Largent uses Nolanea subcapitata, not Entoloma subcapitatum. For Dave's note on this find see the Humboldt Bay Mycological Society newsletter, Mycolog May 2022, page 10. Voucher collection is RHM-22-3.
I think! Hopefully doing some microscopy today.
I think...very shiny/silvery and shaggy stipe that made me hope for Pouzarella, but seems unlikely from the cap texture. Microscopy shows caulocystidia/tufts near stipe apex, spores, two potential cheilocystidia, then the pileipellis at the central disc.
Microscopy coming (I think this is the same as one DL has already IDed for me. Will check on this).
The last two images show some of the cells in the pileipellis. My section from these just squished, so no good intact views to show.
Pink spores. Still need to look at it under the microscope. Nolanea?
