Pluteus is a complex and tricky genus, and there is no published North American monograph for it. There are a number of papers that deal with NA Pluteus in more or less limited ways, but probably none by themselves would be much help getting a name for this one, especially without microscopy.

The cap surface is important for distinguishing between the three sections, but even that can be tricky from a photograph as Fredo pointed out in your more recent observation.

Different Location, but I believe it is the same species. I hope the photos are adequate- that’s the highest magnification I can achieve right now.

Thanks Drew!

Is there any literature you would recommend regarding taxonomy or phylogeny that might help me get into the right ballpark? Id really like to get this one to species, it is by and large the coolest Pluteus I’ve found yet!

Thanks, and ill do my best to get some macro pics today.

in romellii is usually prominent from the beginning, especially near the stem base. The gills are yellow early on as well. Micro features are really needed to get very far with most Pluteus, or at least a very sharp closeup of the cap cuticle might be helpful.

Is strongly obvious in the specimens that had sporulated. I will try to get pics today…

As far as the lined cap… Of all the descriptions of American pluteus that I looked at, Only a finely lined margin is mentioned in yellow species.

I would be thrilled to consider any alternative suggestions.

and strongly striate cap do not indicate P. romellii.

Mycenoid stature

Pileus was broadly convex, slightly umbonate, deeply striate. Dark brown, becoming tan, Darkening toward umbo.

Gills started pale,becoming flesh to vivid pink. Nearly crowded, forking. Edges smooth,

Stipe near translucent, yellow tones present toward maturity, hollow. Minutely flocculose at base.

I did not observe yellow gills, but lutescens seems plausible.

I think it was just doing that thing that little Pluteus do.

bluing…
