Observation 81492: Cortinarius cotoneus Fr.

When: 2011-10-21

Collection location: Thoiry, France [Click for map]

Who: Douglas Smith (douglas)

Specimen available

Found under oaks, beech, fir.

Cap fibrous olive brown, gills olive-brown, stipe tan, cottony on the base, two veils. Stipe and cap non-viscid. Context brown in KOH, Cap red in KOH.

The micro-shot is spores from the veil at 1000x in KOH. The spores are sub-globose, brown, warted. The apr. size is 9 × 7 um.

This one, I had figured for a rather large C. venetus, which I also found on this hill side the next day. But looking in Funga Nordica, with the spore size, this seems to be clearly C. cotoneus. Which if this is C. cotoneus, then I’m not sure what we are calling that in California…
