Collection location: Fraser Experimental Forest, Grand Co., Colorado, USA [Click for map]
Another Colorado Cortinarius which seems to lack a name.
The cap appeared dry, somewhat virgated, and up to 7.8 cm across.
KOH on the cap gave a slight red brown color.
KOH on the other surfaces was neg.
The spores were ~ 8.4-9.2 X 5.1-6.1 microns. They were relatively smooth and many displayed an oil droplet(in KOH).
I changed the proposed name to Cortinarius talus based on the suggestion from Dimitar and the similarity to at least the western NA version of the European species.

Ron, great observation — this one comes closer to the vicinity of Cortinarius talus, the way we interpret it in the American West. I had one sequence, which was not very good for a confident judgment, but it still indicated closeness to the European material. I will get a better one eventually.
Here is a similar collection from California.
