…see Cortinarius caperatus, the former Rozites caperata, which has a membranous, not fibrillose, partial veil.
As to the ID…a distinctive feature is the mottled gills with white edges.
Arora describes the veil in this mushroom (listed as Psathyrella velutina in MDM)as “fibrillous-cottony” and in fact many mushrooms other than corts can have a cortina…like the hygrophorus. I have even seen cottony fibrillose veils on amanitas!
rules are for our convenience, and the mushrooms don’t necessarily obey them.
The genera with species that display a cortina are multitude. Actually these here would get classified as a fibrous partial veil, but not really a cortina, and this id is pretty good (if you can, check for warted spores. I think I posted a fairly good photos of the spores here…). A cortina should be fibrous, but also attach to the stipe over a largish area, not just in a single ring, like attach to parts of the whole top 1/3 of the stipe. (At least this would be my def.)
A number of genera display this, Cortinarius displays it for all species though.
(What ones? it is there for a number of Inocybes although slight, Galerinas also, I guess Kuehneromyces would be called that, Only the two species of Tricholoma (at least for the west, are there more in other places?), Some Hygrophorus, and others I’m sure…)
One young one clearly has a cobwebby partial veil.
Is this a sign of misidentification here, or do I need to add Lacrymaria to the list of genera with cortinas? (MushroomExpert indicates Cortinarius is the main genus with easily noticeable ones leaving discernible remnants on mature specimens, and Inocybe have cortinas when young; some Tricholomas too.)
