I’ve been wondering about this one!

I think your instinct about this was right about this, Cindy

As Michael Kuo says about G. dryophilus: “….but it fools you, again and again.” I have now sequenced a few collections of these including this one:


R.prolixa in the U.S.?

I can’t find occurrence of R. prolix in the U.S. checking either M.O. or iNaturalist. I should mention I did get confirmation (from photos) from 2 longtime mushroom identifiers from the Arizona Mushroom Society one who has been actively sequencing mushroom collections from Arizona for a number of years. But saying that I do have some lingering doubt if it is a Rhodocollybia because of my difficulty in seeing serrated gills from my poor quality gill photos. Considered R. badiialba but these appear too slender. Not certain if cap color would be in the realm for Gymnopus dryophilus but I think that could be a possibly. Wish I had collected and dried these!

Hello. The photos are not like Rhodocollybia butyracea (the stipe and also the cap colours are all wrong). To me at least the 2nd & 3rd photos look a lot like R. prolixa (also known as R. distorta). I only know European fungi (which include a load of R. butyracea everywhere).
