Collection location: Fraser Experimental Forest, Grand Co., Colorado, USA [Click for map]
These were growing semi-clustered with mixed conifers at about 9200 Ft.
The caps were up to 11.2 cm across and were slightly tacky.
The gills were tan to light brown at this stage.
KOH on the cap gave a reddish brown color.
KOH on the cap flesh was sl. brown
KOH on the stem appeared to be neg.
KOH on the stem flesh was similar to cap.
Spores measured ~ 8.2-9.1 X 4.8-5.5 microns and seemed moderately rough.Cortinarius multiformis may be a possibility as that species was identified at the Foray. Not everything seems to fit however. I don’t know if this collection was ever identified.

This is an interesting one. The spores suggest something closer to multiformis, but that gill color – is it really lilac-purplish? And the KOH reactions suggest other things, more Calochroid in nature. We have some peculiar Corts in that group – still the spores are on the small side for anything Calochroid. Don’t know what to say. An interesting one for sure.D.
