for the document says Megacollybia subfurfuracea pileus colors with distinct olivaceous
tint, becoming neutral brown upon drying.

Others macroscopic features seem to fit. I would not call it dry but maybe I am wrong

M. platyphylla form A differes by having purple instead of brown according to Rep. Tottori Mycol. Inst. 45 : 1–57, 2007. So its either new or marginata. Ron has it so hopefully we will find out. I have to do a little checking to see if I see any photos from other locations.

I will try be more careful with my wording.

M. marginata is currently only known from “temperate east Asia”.

There are only two Megacollybia species described in “Megacollybia (Agaricales)” as having marginate gills. M. marginata and M. platyphylla form A. I wonder if this is a new species or variation.

to put that more precisely – it is a species described based on Russian type specimens, with an unknown range in a global sense.

It’s important to keep that in mind since many specimens described from a give area (and sometimes even named after that area) end up having much larger (sometimes rather cosmopolitan) ranges.
