your specimen doesn’t show a “long tapered pseudorhiza” as described in Smith, although it does show scattered rhizoids at the base. long and tapered makes me think of a phaeocollybia, not Clitocybe albirhiza with rhizoids.
did your cap context yellow when cut?

olympiana should have a bitter taste, too…

I agree with Pholiota as a genus…

not sure about the olympiana designation.

Smith’s “North American Species of Pholiota” sez the spore print for olympiana should be cinnamon brown, and that it grows with doug fir stumps. although this book contains many fine B and W photos, alas, no photo of olympiana. your photo looks like the mushrooms were viscid as well, a feature not mentioned in smith’s book. also, the stipe as described for olympiana is long and slender. I’d say back to the drawing board for species ID!

Pholiota olympiana?

Spore print was light brown so I was thinking this might be it. Still need to do microscopy. Has anyone ever seen olympiana before? I can’t find a photo.


I also vote pholiota and yes to pseudorhizae.

Would you guys call the things at the base of the stipe here pseudorhiza?

Awesome pictures of the diagnostic features! A spore print would be great to clarify this but I would venture to say this is a pholiota species… I can’t think of any gymnopilus species in our area that has a veil like that… the Lamellae also look awfully pale…

More photos and exact measurements

..now added. Spore sprint shortly.

Need more data…

Hopefully ‘more to come’ means we’ll get some photos of the hymenium. I expect spore color is also going to be important. At a guess I’d say these are Gymnopilus, but they might be Pholiota.
