Found in middle of dirt track through a wooded area, under mixed woods.
I put a gill from one of these under the scope, and with the over-all body form and the smooth deep cocoa brown spores put this in Psathyrella, they were roughly 11-12 um by 6-7 um. There were cheilocystidia on a fertile edge, and these were lageniform, with an acute apex. After a little closer looking I could see the pleurocystidia on the gill face. The basidia were all 2-spored.
Looking in the two sources, this pretty much put them in P. prona. Except for the 2-spored basidia, it seems P. prona should be 4-spored. But there was a note in the Van Waveren source that in many of the P. prona var. prona f. picta specimens they were 2-spored. I find it a little interesting here that the presence of 2 or 4 spored basidia don’t even separate species. That this author (and others for this genus?) will accept 2 and 4 spored forms in the same species description. This seems to split species in the recent Galerina and Conocybe/Pholiotina studies.
It then mentions that these specimens were from France, and that this form exists in France, rare in Holland, and not at all in the British isles, so I’ll go with it.
