Laccaria amethysteo-occidentalis is a mushroom found under conifers, usually pine, growing alone, scattered or gregariously in western North America.[2]

Description

The mushroom is entirely purple.[3] The cap is 1–7 centimetres (1⁄2–2+3⁄4 in) in width.[4] The gills are purple.[5] The stem is up to 14 cm (5+1⁄2 in) long, fibrous, with a whitish mycelium near the base.[3]

The spores are 7.5–10.5 x 7–16 μm, subglobose or broadly elliptical. The spore print is white.[3]

Similar species

This species is similar to L. amethystina[3] but differs by occurring in hardwood forest in eastern North America, rather than coniferous forest; having a smaller sporocarp; and being a lighter purple color.[citation needed] L. bicolor is smaller and less purplish; L. laccata has whitish mycelium at its base.[6] Cortinarius violaceus is darker and has a less fibrillose stipe.[6] Pseudoomphalina cokeri is also similar.[3]

Distribution and habitat

It can be found on the ground near the North American West Coast from October to February.[3]

Uses

The mushroom is edible.[1]
