Collection location: Thoiry, France [Click for map]
Found oak, hornbeam, and fir.
Cap viscid, stipe not viscid, with bulbose base. Gills lilac-grey, white rhizomes at base. All tissues stain bright rose-pink in KOH.
The micro-shot is of spores from the veil at 1000x in KOH. The spores are ellipsoid, brown, warted, with a smooth point and no germ pore. Apr. size 10 × 6 um.
Putting this together with Funga Nordica, this one drops out rather quickly as Cortinarius arcuatorum. The all tissues turning bright rose pink like this makes the id actually fairly easy.

Then I guess I’m not really going to be a true Cortinarist any time soon it seems…
hardly accepts a single, dried out specimen as a collection.
That’s why keys are so hard to follow.
You are expected to have them fresh and in several stages, from buttons to grown out caps in order to recognize the described colours (on caps, veil and flesh etc.). Like you said, the colours fade and can change considerably with age and on drying. So, I can’t argue for or against any particular name here.
Yes, but those are young fresh, damp guys, this one was an older, very dry guy. Not sure it is that far off, once it dries out? The rose-brown color…
take a look at obs 32161, you will see a difference in colours..
Ok, maybve I need more sources, and ok, I think one problem with corts, is that no one seems to be able to write a reasonable key… without twists and turns, and surprise traps for the unwary.
But from the descriptions in Funga Nordica at least, it doesn’t seem to match with the description of C. dibaphus. Which says the cap and stipe should violaceous, and that the stipe has a relatively narrow, not sharply marginated bulb. The habitat and spores do seem to work for both really.
Or are you joking with me, and these are synonyms… boy the desc. there are really close in both…
This reminds more of dibaphus if you ask me
