to examine the gills on wood-inhabiting mushrooms that seem to qualify as species of Gymnopus. It looks to me like the thickness of gill edges (as well as the width of gill faces) may be something that varies considerably, even within one collection of (presumably) certain Gymnopus types.

So I’m now doubting the relevance of my previous comment.

I find the distinctions between some types of Gymnopus and some types of Marasmius to be puzzling.

seem to not match either G. dichrious or G. erythropus.

that points toward Gymnopus?

Stipes were wiry, somewhat rigid.
