Cort Evangelism…

special thanks to you and BAMS for allowing me to do my Cortinarius Evangelical work in California. BAMS was the first temple we built…

Seriously, let’s deal with Sections for now, or general affinities — I will produce more material for people to read and appreciate. Names are not near yet.

Now I am seeing that a lot of those names that the “road warriors” put actually are in a midst of species complexes, so it is not clear exactly which one they had in mind. Take these volvate Corts, for example — I have several collections, representing more species than Smith wrote up and Moser later re-collected. The picture is more complicated, but we’re on the right track to do a sustained effort to try to answer some questions.

Later, gotta run now to the Cort Orchard…

Now we speak the same language…

Yes, Richard, all of a sudden the Corts disappear once you start looking for them. This is worth a separate long thread. The other day at SPSP I walked a mile before I saw one Cort. Almost got frustrated like a little boy and wanted to just go home.. And then bingo, saw one, saw a second, and then the place turned to be a Cort orchard with 8 different species… Some Phlegmacia off the charts. You’ll put a little flora when I have a chance. So, once you find one, look around, there are likely to be more lurking around. It has something to do with the soil, be it calcareous, or other factors, not sure.

Glad to see you collecting — this is exactly what we need a force of educated collectors — since we’ve become serious to collect heavily Corts this year, some interesting outlines are starting to emerge. The one you show here is a new one to me – a veiled one. Please keep an eye for more, they are likely to be there.

You’re the man!!’


P.S. Taking Paul Nagami in an hour or so to my secret Cort Temple here in Mendocino — some large and diverse Phlegmacia, unparalleled in beauty, as if planted…

you just have to submit it twice.

See Dimi, you have already been an evil influence on us…we are bravely attempting those subgenera designations now.
Could actual Cortinarius species be far behind??! well, yes, probably. but still…it’s a start!

Still have it.

I will send it to you. Have at it!
I learned a lot at your talk the other night. The part I am really only beginning to understand is why I see so few Cortinarii. I think it is a question of the habitats I normally look in but also my overlooking them. This specimen was growing in the middle of a trail and was evidenced only by a slight raising of the redwood leaf litter. If it had grown large enough to make itself known it would have been too old to identify.

Definitely a Phlegmacium

Very nice Richard. I see KOH brown. Cool. Did you preserve this one — we have a number of species in the PNW that leave a massive amount of veil on the cap. They are complicated group with a couple of names published by Smith, but definitely there are more. If you preserved this one I’d be grateful if I can study it.

The Lithocarpus is the host of interest in this case. There must also be Douglas Fir. I call that California forest “Type 1” — Redwood, Douglas Fir & Tanoak…

Why does MO default to Subgenus sericeocybe?

Isn’t this in Phlegmacium?
