May be C. anomalus

I’ve seen this species many times during this season and I agree that morphologically, it matches the species description. This group needs a revision. I know there are undescribed species in this group on the West Coast. I have DNA sequence information from Europe where they name two different genetic species C. anomalus.

There are so many Corts out there…

But I think you nailed this one, Emma. Phillips’ account matches very well. In particular, the hollow chamber in the stipe seems like a good macro-character. Still, when it comes to Cortinarius, except for a handful of distinctive exceptions, assigning a species name is tricky.

Thanks Emma.

I’ll check out the literature for this species complex name. I think I still have a little material from this collection at home.
