Who: Douglas Smith (douglas)

Specimen available

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.
