Cortinarius alboviolaceus

provided by wikipedia EN

Cortinarius alboviolaceus is a basidiomycete mushroom of the genus Cortinarius native to Europe and North America.

The mushroom is lilac, later yellowing and often becoming whitish/grayish.[2][3] Its cap is 3–8 cm wide, conical to umbonate, dry, silky, with whitish to pale lilac flesh.[2][3] The gills are adnate or adnexed, grayish lilac becoming brown as the spores mature and lend their color.[2] The stalk is 4–8 cm tall and .5–1.5 wide, larger at the base, sometimes with white veil tissue.[2][3] The odour and taste are indistinct.[3]

Its edibility is considered unknown by some guides but it is not recommended due to its similarity to deadly poisonous species.[2] At least one guide considers it edible, but not recommended.[4] Conflicting accounts indicate that it may itself be poisonous.[5]

Similar species

Similar species include the essentially identical Cortinarius griseoviolaceus, as well as Inocybe lilacina.[2] C. camphoratus is similar, but with a foul odour. C. malachius has a grayish cap and, when dry, a scaly surface.[3]
