Observation 29351: Cortinarius infractus var. obscurocyaneus
When: 2009-12-01
Herbarium specimen reported
0 Sequences

Notes:
These were found growing near Madrone and Bishop pine.
While they were not obviously viscid, they were a little sticky and holding a lot of debris. The flesh was light violet.
KOH reactions; cap…reddish brown, cap flesh..sl. darkening, stipe..no reaction, stem flesh..sl. darkening.
The spores were approx. 7.6-8.8 X 5.2-6.5 microns. The distinctive characteristic of the spores seemed to be that they were rather heavily warted for a Cort.

Intriguing…

Well Ron, it can be something interesting. Let’s do this — just keep the collection, but I’d appreciate if you can save me just one half or less of a fruitbody for me. I hope to see you this weekend at the MSSF Fair. Will exchange a pair of reading glasses for a piece of that interesting mushroom.

Dimi-not bitter to my taste.

I kept a dry piece of the cap in my mouth for about 3 minutes without detecting any bitterness. Melzers on a dried piece of cap and cap flesh turned turned dark reddish brown and stayed that way for over 10 minutes.

It does bother me a bit, yes…

Yes, the copious cortina does bother me a bit as it is not typical for the species. The light colored gills bothered me even more. In general, Cortinarius bothers me big time… But the spores shape and size leave very little room to play with, so if Ron comes back and tells us that this is not bitter then we have some work to do — I’d request the dry material and I can taste it if bitter there too.

Copious cortina

Dimitar – the photos of C. infractus var obscurocyaneus on your website show much less abundant cortina material than that of this collection, which made me wonder:
Is the amount of cortina present something that you find is taxonomically valuable, or is it rather variable for most species?

Hmm, infractus…

Ron, the spore shape and the water marks on the pileal margin suggest strongly one of our species of infractus, probably something around var. obscurocyaneus — but please TASTE IT — it should be bitter. If not then we have something very interesting, but I doubt it. If not bitter, please slice and put some Melzer’s on the context and let it stay, minimum 10 minutes. Let’s see what color we get then…
