yup, dried mushrooms can look very different than fresh.

nice detective work. if this is our only Pholiota with these macro characters, then perhaps a photo is enough.

Yes, many Pholiota sp. can look alike in the micro … but the cap characters were supposedly unique, according to one who dove deep into the genus aka wrote the book. If you don’t have a copy of the Smith and Hesler book at home, it is up on Mycoweb, for anyone else who wants to read the deeper details.

Why not do a synopsis here on MO for the species description?

If you ran the DNA on as many similar Sierran/Cascades Pholiotas as you could obtain, and they all came out the exact same species, then it looks like this could be a reasonably simple ID. Until we discover otherwise, somewhere down the road! :)

they didn’t pull up yesterday in a search.

but it looks like you did all of this novel ID work yesterday. Timing is everything!

None of these photos show the green gills tho .. got some?

Alan’s photo clearly shows the yellow-colored slime coat.

Ah yes, the mushroom formerly known as Vellingae … guess that you did the deep search necessary prior to a nova pub and found it was already named.

So … just a single Sierrran/Cascades species has these macro-characters (and yes, the micro is a slam dunk, but no data provided here), such that they can be clearly IDed from just a photo? Which specimens had their DNA run? The Yosemite FS? Gosh Noee, you were collecting with US on that project.

Good times, past life.

I have a few

surely you ran DNA on your own collections. why not show us what they look like, so we might compare with these, which have NOT been determined by DNA or microscopy.
