Collection location: Fraser Experimental Forest, Grand Co., Colorado, USA [Click for map]
A single specimen collection but at least it looks in the prime of life.
The cap was 5.6 Cm across and was a little tacky.
The gills were lilac colored.
The spores were ~ 10.0-11.2 X 6.9-8.0 microns.
KOH on the cap gave a bright pinkish red.
KOH on the cap flesh was slightly pinkish.
Forgot to note other KOH reactions and left the specimen with the NAMA folks.

Seen exactly/almost the same in Idaho. It fell neatly in the Callochroid clade as the KOH shows clearly – do not have the exact data in my hand. In general, these fall in the group around Cortinarius olympianus, but are not all the same species… I have to do some more research within the American authors, but last I checked it didn’t see anything – which is remarkable since this is a very outstanding looking Corts and Smith did roam these woods in the 30’s… It is likely that they all considered them to be C. olympianus. I do not have handy the photos from my Idaho collection, but here is one of the blue with pink reaction:
