those very sightings here on MO are exactly why I asked Irene this question. My point is why assume that these perfectly purple-gilled forms are a Cortinarius
trivialis (as was proposed for some of these sightings), when those gills don’t match any known description for the species?

Cryptic species are everywhere, and corts are just one of those rabbit holes of taxonomy.

Perhaps throwing it into a trivialis “group” designation is the wiser course.

found by Richard Sullivan that have deep purple gills…

I have seen patches where the young gills are lilac-purple, but usually they are pale smoky-gray, with a faint lilac tone.

there is a form common in Santa Cruz (at least) associated with Live Oak that frequently shows gills strongly suffused with lavender-lilac
tones… but I don’t think I’ve seen the gills be ‘completely’ of this color and definitely not consistently.

I’ll look through my photos later

I don’t know, Debbie

I have seen a dark-capped small form with oak with bluish gills, and a more common and larger one one with a paler cap and ochraceous grey gills, but not seen or heard of any with purple gills, although the description “violet gray” may be a little closer.
In my books, they are still treated as a complex of species.

speaking of which, Irene…

although a slight blue/lavendar tinge to young gills is mentioned in a number of descriptions of C. trivialis, for both Europe and NA, are those gills EVER completely bright purple? Or would that perhaps be a cryptic species within this group?

it belongs to the Cortinarius trivialis group. There is one Populus form, and I think one with oak too. I don’t know how many others..
