You are right, Dimi

I haven’t had any reason to beleive that american species or varieties should look exactly the same as in Europe, neither with the same colours, nor size of the spores. As you wrote in another comment, it takes a bit more to describe and ID a Cort – chemical reactions in different parts of the fruitbody, info about taste and smell for example.

Comment on the C. caerulescens suggestion (per Irene A.)

Irene,

the Caerulescentes and Glaucopodes are closely related, neighboring
clades indeed, per molecular studies. The American representative of
the C. glaucopus complex has a rather bluish cap margin, particularly
the collections under broadleaves, such as Oak. The way the photos
were taken by James G. and the absence of straight top shot created
the possibility for confusion with caerulescens. Yet, credit goes to
James for having produced excellent spore shots. These rule out
caerulescens having spores range of 8-10 microns, while if I interpret
right his picture, the spores are no longer than 8 microns, which is
typical for C. glaucopus. Having seen quite of few of C. glaucopus in
North America I’ve noted that unusual
(somewhat) feature of bluish margin. Just look at some of my
collections:

Oh my, all of you back to class, at once!!

Ladies & Gents,

come to my Cortinarius class later this Fall. If the fervor for
commentary is matched by a miniscule desire to learn then the name of
this Classic Bulbopodium should have never escaped any of you. This is
clearly listed on MushroomHobby.com. One of the classics — Top 10
Corts of all time…

Hint 1: LOOK AT THE TINY SPORESRATHER UNUSUAL FOR A BULBOPODIUM, HUH?
Hint 2: LEARN THE MAJOR SUB-GEN/SECTIONSIODES??, WHAT THE HELL?

James, a shot of the upper part of the cap is a must. How else can
people see the texture of the cap — this one has an inner-fibrillose
cap under the viscid cap (=Phlegmacium, damn I’m dropping hints like
manna for the hungry here)

For those who collect Corts — KOH reactions, taste, odor, etc. are a
must.

Have fun, it’s easy! Just think…

Doesn’t really look like C. iodes

There are whole sections of Cort. that have bulbous bases, and are purple. Actually this one is “abruptly” bulbous, there is a small shelf at the base. The cap margin was attached to this shelf as a button. This is not a feature if C. iodes. Also C. iodes should be thinner and more graceful, and have the white spots on the cap.

not iodes, but what it is…???

a quick “google images” search showed me a mostly slender mushroom with a sometimes rounded (bulbous) bottom, not squat and grossly bulbous like these. also, iodes is sometimes called the “spotted cort,” due to the frequent presence of yellowish spots on the cap with age. it is also drippingly viscid in youth.
I don’t believe that you have iodes pictured, but what you DO have I will leave to the cortinologists…

I can’t really offer a definitive species but given the two choices so far, it looks a lot more like C. caerulescens than C. iodes.

bulbous stipe on C. iodes

According to MushroomExpert.com "… the stem is often bulbous at the base. "
