Observation 81487: Cortinarius salor Fr.
When: 2011-10-21
Collection location: Thoiry, France [Click for map]
Herbarium specimen reported

Notes: Found under oaks, beech, fir.

Cap grey-lilac, stipe off-white, gills grey. Cap and stipe viscid. No reactions to KOH.

The micro-shot is of spores from the veil at 1000x in KOH. The spores are brown, warted, sub-globose. The apr. size is 8 × 6.5 um.

This seems to match well to Cortinarius betulinus in Funga Nordica p677, esp. with the grey gills, and the grey tones to the purple-lilac cap colors.

Hmmm…

Too sturdy? Not sure I would call these sturdy, as little thin guys… I guess I should move them over to probably Cortinarius salor, since that was suggested by people in the area. Although they did say, well they look Cortinarius salor-like.

Is it just me, or do all Myxacium spores look the same really…

I suspect

that what we call salor, may consist of more than one species, or at least varieties. I’m not really certain how to interprete transiens either. I don’t know how well they have been investigated before they published Funga Nordica (or after).. But I’m rather confident to rule out betulinus, because it’s too sturdy, too dark, and the habitat is wrong.

Cortinarius salor…

C. salor… hmm… this was suggested actually. But I think that the descriptions in the keys kinda moved me a little away from that. There seems to be more grey in these, than the color are described in Cortinarius salor. So I went with Cortinarius betulinus here. It seemed that these almost matched the edge of the desc. for Cortinarius salor, but were right in the middle of the desc. for Cortinarius betulinus. Need to look at more sources on this one I am sure, although that might just confuse the issue in the end.

Interesting with your suggestion of Cortinarius transiens here, and in the similar obs. from a few weeks later:

Since these are really both from the same hill side (although a couple 100m away). But the habitat was rather different, here it is oak, beech and fir, and in the other one it is spruce and fir. Maybe fir is the common ground if that similar…
