Irene, after reading the descriptions I agree with you… I’ll leave this to Dimi.

I give up

It woulda been nice to have shown photos of them here, but if red in context, red-brown in cap, it does sound like C. fulmineus etc. etc.

I have to assume that Noah was with Darv when he collected these, since he did the KOH on them. In hand color trumps photos every time.

I didn’t see lilac.

They were more grayish. But, yeah. Not yellow.

KOH rxn was bright red in flesh, dark reddish-brown going dark brown on cap.

do you read that “Cortinarius fulmineus sensu Moser & Ammirati” has lilac gills?
Don’t you agree that this one has?

2 views by Moser?

From the paper by Bojantchev & Davis:
Moser MM and Ammirati JF. 1997. Studies on North American Cortinarii IV: New and interesting Cortinarius species (subgenus Phlegmacium) from oak forests in Northern California. Sydowia 49(1): 25–48.

OK Noah

See http://mushroomobserver.org/28207 for a lively discussion on this species….

I suggested the name to Darvin, after comparing it to the pictures in
“Cortinarius xanthodryophilus sp. nov. -a common Phlegmacium under oaks in California.” Bojantchev & Davis.
Cortinarius xanthodryophilus

Interesting suggestion

but Cortinarius fulmineus sensu Moser is something else – a phlegmacium that is completely yellow to orange, including the gills (sect. Fulvi).

This reminds a lot of C. caesiocortinatus..
