Observation 56812: Cortinarius subgenus Telamonia (Fr.) Trog
When: 2010-10-19
Herbarium specimen reported
0 Sequences

Caps less than 4 cm across and tending to grow in clusters.
They had a fair amount of violet tints especially on the upper stipe.
Also on the stipe a thin ring and underneath somewhat fibrous.
Spores were ~ 8.5-10.0 X 6.0-6.1 microns and less than moderately rough.
KOH on cap gave a light brown reaction.
C. flexipes seems somewhat close but not all references note the violet tints.

Irene and Dimitar…thanks for Telmonia mini-course

I’ll save these although my “herbarium” is rather unorganized and getting more so. Perhaps something for me to do during those dry summer months.
Collected something similar in Montana

Collected something similar in Montana with very similar, larger broadly ellipsoid spores…

Right. I didn’t realize that the spores of paragaudis are actually that round, but all references indicate so (mainly Soop) – the drawing in CFP shows them more broadly ellipsoid despite stating subglobose. So paragaudis is probably safely out of the window as an id offering. Anyway..

Ron, preserve this artifact and we’ll look at it – it is very likely that it falls way outside of the (little) known state of the Telamonia in the West. You just hold another piece of that puzzle in your hands.

just wanted to mention other groups with red veil, because I couldn’t see any obvious relation to the armillatus/paragaudis group. Other examples are C. praestigiosus in sect. Hydropus; bulliardii (sect. Cinnabarini?).

And paragaudis has completely globose spores, while they are elongated in its cousin armillatus, so I wouldn’t use ellipsoid spores as an argument (at least not the only argument) to exlude a species from a group where they are more globose.

Anyway, this is a very interesting obs. I hope you’ll manage to find its place among the corts. I wonder if the clustered growth is significant too?

Yes, but them spores…

Irene, these do show all of the signs of the anomalus group and I did think that at first, but these spores are not subglobose enough for that group. C. anomnalus and tributary clades stand out with their roundish spores.

on stem, cap and gills, made me think more in the direction of section Anomali.
One example with red veil, is C. spilomeus. It’s not this one, though.
And the striate hygrophanity is not a typical Anomali character either..

The reddish veil…

The key concept here Ron are the reddish veil remnants on the stipe. This tends to suggest a placement in the armillatus-paragaudis lineage. The first is typically associated with Betula, but I think somewhere in this group is the correct answer. There is Cortinarius boulderensis in our area, but it has narrower spores. I collected something similar in Montana, but it is closer to C. paragaudis. An interesting collection, where again, the veil color on the stipe is the key feature. We are very far away from knowing these Telamonia group well.
