Observation 87441: Cortinarius pinguis (Zeller) Peintner & M.M. Moser
When: 2011-09-24
No herbarium specimen

Notes: One has to wonder what evolutionary chaos created this secotioid Myxcaium – its next of kin are some of the tallest and most stately corts – C. mucosus, C. collinitus, etc. (compae to the photo below). This little ugly duckling differs by its erect brethren by merely 3-4 base pairs in the nrITS!!!!

This is also a pretty good lesson in what taxonomic characters are most plastic vs. most conserved – the macromorphology is strikingly dissimilar, but the spores…. The spores are the same (almost). We see that that in closely related species in general it is better to look at macro characters in order to seek differences.

This species appears more common to the North. My first find in Yosemite.

nor “blame” per se, just citing the fellow who taught my physics class in college, and from whom I remember that quote. Disorder/chaos, what’s the diff?
Matter of degree? Hey, I went into the biological sciences, but they made me take physics, so forgive me if I mis-quoted/unknowingly malinged ya. No malinging meant.

Seems like moving to a secotioid form is just another cool aspect of evolution, a way to heighten your advantage in a normally quite dry environment. Not the best place for a normal slimy Phleg, why not expand your morphology choices and adapt to another niche?

Shrooms gettin’ down and funky and thereby conserving moisture.

Now why that cool little coastal Inocybe sp. went all secotioid, I couldn’t tell ya. Not much of a moisture-retention problem up there.

Wait, blame physicists?

Wait a sec., what is to blame? First off, I don’t think any physicist has said anything about life, so nothing to blame there I hope. But the law is that “all systems tend toward disorder”, that a disordered system will have a lower potetial energy than an ordered system. Don’t know about chaos. But this is the reason why it is always easier to unpark a car, then park a car, parked cars are a more ordered state.

seems pretyy weird thing to say. Life and ecosystms in general pretty complex n organized.
Universe has increseing entropy in the long -term, but lots of order in any little pocket of the universe at a given moment

according to Kuo…

this species is common in the Rockies, and also occurs in the Cascades and Sierra.

Any secotioid sp. is cool in my book.

I should have checked. I assumed it is a non-latinizable name. I am naming one C. cisqhale and that’s ok, but in this case I guess that name has to be changed. Whatever Index Fungorum says, I am ok.

Mycobank and Index Fungorum this name is a synonym of Cortinarius pinguis.

very nice.
