Alright, that is what I have been wondering… Sounds like a good explanation, especially since I could think of no other genus for this mushroom.

I think that isn’t a consistent feature…

I think the serrate gills thing isn’t really a consistent feature of Rhodocollybia. It certainly is a subtle feature in Rhodocollybia compared to Lentinus/Lentinellus, and I think at times it be subtle enough to not really be there.

I’d vote for Rhodocollybia on these also. Rhododcollybia makes me wonder, it seems like a bunch of stuff gets put into R. maculata or R. butyracea. But I wonder how broad these species concepts really are…

Actually Hugh Smith sent out a photo recently to a mailing list that looks just like this one, but from the central valley.

Irene, I looked at these photos again really close after your proposal… I see a few lamelle with a jagged edge, however very few and only subtly- enough to escape my notice. So then do Rhodocollybia some times have hardly (if at all) serrate gills?? The Rhodocollybia I have found and inspected always seem to have conspicuously jagged lamelle.
