Recognized by sight: Despite the notched gill attachment, everything else points to C. albirhiza, i.e. heavy pseudorhiza at base, cap shape and zonate texture, habitat. Just doesn’t say Tricholoma aside from the stature and gill atachment. Were all of them like that?

Hi Daniel,

These were growing under mixed conifers, including both Pine and Fir. I’m still learning the western conifers, but according to Wikipedia, the most common pine in the Uintas is Lodgepole pine, and Sub-alpine fir and Douglas fir are also common there.

I would say these are likely associated with the pine, as it was the most common tree in the area where I found the mushrooms. These were fruiting right beside melting snow banks.

Potential hosts?

MO cannot help much beyond Tricholoma without knowing possible host trees nearby.
