Observation 47991: Cortinarius subgenus Telamonia (Fr.) Trog

These were small,caps up to 2.5 cm across, and stems up to 4 cm high. The caps seemed to be partially dusted with yellowish particles. Could have been an environmental factor?
The gills were fairly wide spaced and the spores were relatively large and variable; ~ 10.3-12.0(14.1) X 7.3-9.0(10.1) microns and warted.
KOH reactions on cap and stem were brown. On the upper part of the stem and cap flesh there appeared to be a slight purplish/pink reaction.

Here is the ITS1/5.8S/ITS2 for this one

This is a unique collection that is similar to, but not the same as
any of my other snow bank Telamonia collections. They form a very
distinct 2-3 clades that must have evolved into a minimum of 6-7
species so far (and counting) and fit in different places in the
overall Telamonia phylogenies (but firmly within Telamonia!). Doing
morphology on them will be a major challenge as they do look alike
greatly — this one has more interesting spores and stands apart
actually. Eventually we will publish a nice compendium, but a lot of
work needs to be done and with every new collection it appears that
we’re breaking new ground. The good part is that we actually started
to look critically at that group and so far is by far the most
challenging group of Corts to deal with.



Unusually large spores for that group

Very interesting. Not sure I have seen this one amongst the many collections of snowbank Telamonias that I’ve seen this year. Please preserve!! Good digging! The Shasta region starts to show different character than the Central Sierra and the species follow that tendency too.
