Observation 52957: Cortinarius bivelus (Fr.: Fr.) Fr.

When: 2010-09-12

Collection location: Thoiry, France [Click for map]

Who: Douglas Smith (douglas)

Specimen available

Found under oak, hornbeam, spruce, fir.

Cap and stipe non-viscid, no strong odor, Gills rusty-orange, veil off-white, cap orange-brown to tan, some with slight violet tones on margin. All tissues grey in KOH.

There was a bit of argument about these at the SMG meeting, I think three different people brought in some of these from the area. Some wanted to go with C. laniger, but was kinda shot down in the end (took awhile though…). But also in Champions du Suisse tome 5 there is C. privignoides, which also looks pretty good. But I think these had a kinda double veil region on the stipe or so, so people thought C. bivelus was the better name in the end.

The micro-shot is of spores from the veil at 1000x in KOH. The spores are ellipsiod, brown, warted. Size is apr. 10 × 6.5 um.

This matches well with the spore size listed in Champions du Suisse, but this is larger than the spore size listed in Funga Nordica.
