When: 2010-08-12
Herbarium specimen reported

Notes: Caps on these were up to 5.1 Cm across and seemed dry.
There were some vinaceous tints on both the cap margins and stem apex. However they were more apparent in the insitu photos than when I examined them later.
The spores were ~ 7.9-8.8 X 5.1-6.1 microns.
KOH on the cap was dark brown.
KOH on the cap flesh gave brown
KOH on the stem gave light brown.

Sorry, here is a link to similar collections…

For some reason MO mangles my URL – there is a space between Cortinarius and the name – encoded as 20 — it substitutes the ’’ character with the letter ‘a’

Cortinarius cf. valgus

We have similar Telamonia in California and the broader PNW.

These form a cluster of species that were commonly named C. valgus until recently, but preliminary molecular data (1-2 collections) shows then to not be very close to that species. Charting these will require an exhaustive effort – I have numerous collections from California, Oregon and Washington and plan to add some more this Fall. I’d like to get that collection, if still available.

As usual, excellent observation – sometimes these have an odor somewhat unpleasant, not just earthy or raphanoid, but a bit of sewage…
