Observation 51481: Cortinarius talus Fr.
When: 2010-08-12
Herbarium specimen reported

Notes: 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.

Close to the Western American version of Cortinarius talus…

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.
