which may account for the lack of appendiculate cap margins. Pale cap color (white with a yellow disc) is typical for the P. candolleana I find here, especially when the mushrooms are found during a dry period.

Reviewing a few of the reports in my manuals confirms what had caused me to wonder about the candolleana proposal…. the gills are very dark, and fairly well separated.

I took this collection to NEMF and documented the collection. I don’t recall seeing them on the display table, so I suppose there was some doubt as to the species ID. Byrain (or anyone), is it possible to point out one or two good micro characters? I have looked at spores from a few Psath collections, and they have basically all looked the same.
