Found under oak, beech, fir.

Non-viscid cap and stipe, cap brown, hygrophanous, stipe brown, veil yellow, gills orange-brown, context red in KOH, gills and cap brick-red in KOH.

micro-shot is of veil at 1000x in KOH. Spores are sub-globose, rounded, warted, brown. Apr. size is 8 × 6 um.

shows fluorescence in many Cortinarius species, yellow to greenish in sect. Veneti, blue in Orellani.
You can see an example of that in obs 28051.

Ah, section, not subgenus…

Ah, you have subgenera in Cortinarius, I was calling those sections. So, subgenus, then sections. I’ll take a look later I guess. I’m not sure about C. cotoneus, the stipe, and over-all stature, too narrow and thin, also the veil is bright yellow, not sure that is a feature of C. cotoneus? (Plus the cap surface is rather smooth?)

Anyway, what is one supposed to look for with a UV light? (And how does that help define sections?)

sect. Veneti is part of the subgenus Cortinarius..

U-V light…

Oy, now there is something else to look at? Sec. Veneti, there is another section? I thought I might have gotten the sections down, with Phlegmacia, Telamonia, Cortinarius, Mixacia and such. What might define sec. Veneti? This kinda looked like a Dermocybe to me… and the conext going red in KOH seemed to agree with those.

Have you looked at it under UV-light..? It could belong in sect. Veneti, where you’ll find a better match with colours and spores.
