Too pale

for P. involutus in my experience. I haven’t run across it that often – probably 2-3 times a year locally, usually on conifer stumps at higher elevation. Usually both the cap and gills are nearly black (or quickly blacken with handling), and I’ve never seen the striate gills like are typical in Russula before. “Curiouser and curiouser.” said Alice.

Classic Paxillus sp.

As far as the species name — these are tough. of course, one can always default to involutus, but that doesn’t mean it is correct…

Does look like a very light-colored Paxillus

I’ll agree with Debbie on this. Think it is quite light in coloration, especially the gills and cap. Stipe looks about right.

weird fungus. got spore shot?

why Trich? gills aren’t notched…looks sorta kinda like a Paxillus, with that strongly inrolled margin and browning gills.

Symbiontic, huh?

Guess I ain’t herd of that.

Under redwoods? It has to be a Tricholoma of the group symbiontic with pine trees.

ID needed

The identifiers at the Senguio Fungus Fair would like to know what this one is. It appears Tricholoma like…Any guess on the species name?
