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:
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.

GYMNOPUS DRYOPHILUS yellowish chestnut white white long and skinny

(G. ocior ssp. brunneolus) chestnut (fading) white white stubby and swollen

Not much difference macroscopically….

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
