From the north.

C. brunneo-vernus seems to be one of the more common early spring Corts in my region (northeast Washington). J. Ammirati has identified at least two collections I’ve sent him as this.

Also in sect. Brunnei

Unlike many corts that turn brown this one actually becomes very dark charcoal when it dries and is in the real section Brunnei. This is the first member of that section in California that I see. This cort is not common though. Not one of the more common spring cortinarii. It appears to be far more common more to the North. Debbie, I am sending your material and mine to Ammirati and then to Finland for them to do some tests and see if the Cal. material is exactly the same, which I am 97% sure.

Within two years most of Sierra the spring cortinarii will have names.

brown (cap and context), in the spring, it all fits. easy to remember, too.

Ok, we have some development on this one. This is a species that Joe Ammirati mentioned to me two months ago that they are working on with the Finnish crew. I had never seen it before. Debbie’s collection (here) alerted me about the existence of such a beast and yesterday I actually collected it in the Sierra Nevada myself. This will be published soon and is a pretty good nom. prov. to use.

A new one to me

This is a very interesting Telamonia that I have no clue what it is and even where it fits in the global scheme… The spores are broadly ellipsoid 7-9×6-7µ, not like any of my previous collections. Debbie, two new species in one delivery is very interesting at this stage of the game where I have seen a lot of material from California. Apparently the Northern Sierras may need more attention.

prob. not Martin…

but I am no cort expert!

more info: context cocoa brown, black with KOH.
Taste: mildly cucumber, odor faintly fruity.

White C. alboviolaceus?

Sorry I missed your description so the above should have read pale or cocoa brown C. alboviolaceus…, Dimi – any chance of posting photos of those spores?
