Observation 52961: Cortinarius melanotus Kalchbr.

When: 2010-09-12

Collection location: Thoiry, France [Click for map]

Who: Douglas Smith (douglas)

Specimen available

Found under spruce and fir.

Cap and stipe non-viscid, gills yellow-olive, stipe yellow-olive with brown scales and rings, cap olive-green and yellow with black scales. Stipe context rose-brown in KOH, cap brick-red then black in KOH. Taste mild.

Using Funga Nordica this keys out fairly well as C. melanotus, but using Champions du Suisse tome 5 the id is uncertain, and the photo of C. melanotus there does not seem to have the black scales, although they are described in Funga Nordica.

The micro-shot is of spores from the veil at 1000x in KOH. The spores are sub-globose, brown and warted. The size is apr. 7 × 5.5 um.

The spores match well with sources for Cortinarius melanotus in size and shape.

I’m not sure I like this id, although they match well with the description in Funga Nordica at least. But they appear much too dark and olive-green than other id’s of Cortinarius melanotus in Champions du Suisee, or on-line.

looks fine with me. I have been trying to find it for several years – maybe next week on Gotland..
