Common Names: Violet webcap, violet cort
The fruit bodies are dark purple mushrooms with caps up to 15 cm across, covered in fine, downy scales, sporting gills underneath. The cap surface, unlike that of many other Cortinarius species, is neither sticky nor slimy, though it is occasionally greasy. The stalk measures 6 to 12 cm by 1 to 2 cm, sometimes with a thicker base. The stipe is a similar color to the cap, and covered in wool-like fibrils. Younger specimens feature a veil, but this vanishes quickly. The dark flesh has a smell reminiscent of cedar wood. The spore print is rust-colored. Forming symbiotic (mycorrhizal) relationships with the roots of various plant species, C. violaceus is found predominantly in conifer forests in North America.
