Found under oak, hornbeam, fir.
Cap viscid, stipe non-viscid, gills lilac-grey-violet, cap lemon yellow with brown stains in age, stipe off-white, context pink-rose in KOH, cap red-pink in KOH, no clear odor, taste mild.
At the SMG meeting these were named fairly clearly C. calochrous, people seemed to have experience with these. This seems to be the clear id from Champions du Suisse tome 5. Looking in Funga Nordica it keys out pretty well there as C. catharinae. Looking over the descriptions I have, I really can’t tell what is the difference between the two. But I guess I’ll go with the id from the more local source.
The micro-shot is of spores from the veil at 1000x in KOH. The spores are ellipsiod, brown, warted, with a somewhat narrow end. The size is apr. 10 × 5.5 um.
The spores match well with C. calochrous var. parvus in Champions du Suisse, the other vars have bigger spores. In Funga Nordica things are a little better for C. catharinae, which is listed with slightly, 0.5 um, wider spores, which is a small difference. Other than that, I still can’t quite tell the difference between C. catharinae or C. calochrous still.
Christian Schwarz collection, who found it with primarily Tanoak with Douglas-Fir, there may have been Quercus in the area, too. East side of Chinquapin Road, about 100 yards above the Firehouse, UCSC Upper Campus.
Found under oak, hornbeam, beech, and some fir near by.
Viscid cap, non-viscid stipe, cap lemon yellow, stipe and bulb off-white, gills lilac to light violet, Cap red in KOH, context only lightly rose in KOH, bulb no reaction in KOH.
micro-shot is veil at 1000x in KOH. Spores are ellipsoid, somewhat pointed, warted, brown. Apr. size is 10 × 6 um.
These seem to agree quite well with C. calochrous in the books.
Found under spruce and fir.
Cap yellow, stipe white, context white. Cap viscid, stipe non-viscid. Cap red in KOH, Context pink-tan in KOH, bulb pink in KOH.
Found under oak, beech, hornbeam.
Cap lemon yellow, stipe off-white, gills pale lilac. Cap viscid, stipe non-viscid. Cap pink in KOH, context light pink in KOH, bulb non-reactive in KOH.
The micro-shot is of spores from the veil at 1000x in KOH. The spores are amygdaliform, warted and brown. The apr. size is 10 × 6 um.
This matches well the descriptions in Funga Nordica for Cortinarius calochrous, p697. With the lighter yellow caps, lilac gills, and found under hardwoods.
On cones of Picea glaucum
Thanks to @ikholm for teaching me this fungus!
