I found some purple mushrooms while I was away.

In order to try to figure out what they were, I took spore prints. They turned out to be the rusty brown colour characteristic of mushrooms in the Cortinarius genus. Salvelinas has suggested, and I think he may well be right, that they are Cortinarius iodes, based on the description in Barron’s field guide. Telling is the sliminess of the caps. Michael Kuo’s description fits the bill too and can be found here.
