I looked at the pictures of your other specimens. I would say that Cortinarius marylandensis would be the closest match, except that the pileopellis looks to be a trichoderm, not a cutis. This species has the smooth, ellipsoid spores that this specimen has.

Interesting…

The spores are smooth, which makes me want to lean towards Tubaria. What was the substrate? What color does it turn in KOH? The Cortinarius sanguineus group species will turn red while those in the californicus/marylandensis group will turn purple. Tubaria may not change in KOH. Is it hollow inside? Did you find any cystidia?

The cystidia are not yellow tipped

the apex absorbs congo red more than the rest of the cell.
