Cortinarius

Found along the Herman Creek Trail
Hike 10/21/14 Oregon Wild lead by Wendall Wood

Leah said on Whatisthismushroom:
"Yes, this is a Cortinarius!
While I agree that the gill attachment on the left of the 3rd picture looks free,
I'd say the one on the right is more... adnexed (narrowly attached).
Cortinarius are generally listed as adnate or adnexed.
That is definitely a tricky one.

The ring is indeed from a cobwebby veil.

Also there are not too many lavender colored mushrooms out there
in my experience so far.
Most of them seem to be Cortinarius.
So if you find a lavender mushroom with a
cobwebby ring and rusty spores,
there's a pretty darn good chance it's a Cortinarius.

Other possibilities of lavender mushrooms I know of might be

Lepista/Clitocybe nuda (the blewit) but that would have a whitish pink print,

Laccaria amethysteo-occidentalis would have a white spore print, and

potentially maybe some Inocybe species, which would have a straight brown spore print. From what I can tell, purple Inocybes are not common in the PNW (someone correct me if I'm wrong, the only one I can find is

Inocybe geophylla var lilacina), while purple Cortinarius of many species are. You can check out a few of them here: http://www.svims.ca/council/Cortin.htm"

Other info from the Web:

Lepista/Clitocybe nuda (the blewit) whitish pink print The gills are attached to the short, stout stem. Mature specimens have a darker color and flatter cap; younger ones are lighter with more convex caps. Wood blewits have a very distinctive odor, which has been likened by one author to that of frozen orange juice

Clitocybe Odora Gills slightly decurrent, close or crowded, broad; whitish tinged with cap color. Stem 30-70 x 5-15mm, solid becoming hollow, sometimes curved and enlarged toward base o ring

The fruit bodies of Cortinarius camphoratus have a cap that is initially convex before flattening out, sometimes developing a broad umbo; the diameter ranges from 4 to 10 cm (1.6 to 3.9 in). Initially curled inwards, the cap margin uncurls as the mushroom matures. The cap, which is covered with minute fibers matted on the surface, is buff with tints of lilac, although golden tones typically develop in age. The flesh, colored lilac to purple, has no distinctive taste,[6] and an odor that has been compared to "curry powder, rotting meat, old goats or goat's cheese, cold mashed potato, burnt horn, or sweaty feet." The gills have an adnate attachment to the stipe; they are initially pale lilac when young, but become rusty-brown as the spores mature. The stipe measures 5 to 10 cm (2.0 to 3.9 in) long by 1 to 2 cm (0.4 to 0.8 in) wide, and thickens towards the base. Roughly the same color as the cap, it is solid (i.e., not hollow), and covered with silky white matted fibrils up to the level of the annular zone. The latter feature is formed when the cobwebby white partial veil collapses on the stipe. There is general disagreement about the edibility of the mushroom: it has been described as edible, inedible, or somewhat poisonous. It is generally not recommended for consumption. Mushrooms produce a rusty-brown spore print. The spores are pale brown, elliptical to slightly almond-shaped with minute, well-separated warts on the surface
