Summary: Could be worth an investigation

I don’t mind taking a step back here. One thing that speaks against phoeniceus, is the dark context – but it is not the “true” sanguineus, which I know quite well.
However, there is one variety mentioned from mixed woods in Tennessee and North Carolina, Cortinarius sanguineus var. subcinnabarinus Ammirati & A.H. Smith. It only got a provisional name, and I can’t find any more info about it.

Summary: Yellow stipe

According to what I’ve read Cortinarius phoeniceus has a yellow stipe with reddish veil belts. This one had very little yellow, a couple had a tinge at the apex.
I don’t know either Cortinarius phoeniceus or Cortinarius sanguineus well, I’ve only seen one fresh specimen of sanguineus never seen phoeniceus and only seen phoeniceus var occidentalis once.
p. var o. looked nothing like what I collected yesterday… But calling it sanguineus was also a long shot.
