The angle of these photographs obscures several features that would be useful to confirm an identification, and we of course lack a spore print here.
The sheen in the photos makes the cap appear slimy. Running with that assumption, we're immediately narrowed down to a subgenus of Cortinarius called Myxacium. Despite having a lot of purple mushrooms (and some green ones), Cortinarius is largely a genus of poorly described brownish species (a couple of which, it should be pointed out, are lethally toxic).
But there aren't a lot of options for the purple-and-yellowish mottled cap in that bottom picture. So I'm going with C. iodes as my tentative identification. For comparison, here is a very nice pair of C. iodes by a professional photographer.
