Gymnopus brunneolus

has obviously not been known well enough for anyone to make the combination with Gymnopus. It was described by Vilgalys & Miller as Collybia brunneola, later Vilgalys reduced it to a variety of ocior.

This obs has affinities to ocior (chestnut cap, fading with yellowish patches and finally to a pale pinkish brown), but I have never seen it as pale on stem and gills as this one, they are usually some shade of yellow.

I haven’t been able to find any convincing picture of brunneolus, maybe this is it?
What I can read from this key:
http://www.nybg.org/bsci/res/col/index.html
is that brunneolus could be an american form of the european Gymnopus ocior.

Oh, the species comparison

summary in my last post was from Michael Kuo’s website.

I have not recognized this species and don’t recall ever seeing it at a foray.
If it is a good species, it has no doubt been called G. dryophilus.

is indeed a very variable species, but it’s something about the very narrow gills that is disturbing to me. Could it be “Gymnopus brunneolus” – if you are familiar with it?

Gymnopus luxurians

Or what I recognize as that species I have always found in wood mulched flower beds. It is tougher and illustrated in another posting. It is always in dense clusters. This is classic G. dryophilus to me.

I suspect this is luxurians too
