Cortinarius ponderosus, also known as the Ponderous Cortinarius, is a basidiomycete mushroom of the genus Cortinarius. It is very large and due to its thick stem it can be mistaken for Boletus edulis.
Description[]
This mushroom is one of the largest mushrooms in the genus Cortinarius, with a convex cap that ranges from 10–30 cm (4–12 in)[1] and becomes plane in age. It often has an olive metallic tinge, and the surface is viscid, often with small rusty brown scales.[1] The margin is ocher and remains inrolled until the mushroom is fully mature. The flesh of the mushroom is yellow-white, thick and firm, with a mild to sour odor.[1] The gills are rusty brown, adnate[1] and slightly decurrent. The stalk is 8–20 cm (3–8 in) thick, 4–10 cm wide, and bulbous at the base.[1] It has a slimy yellow universal veil, and the cortina leaves a rusty brown hairy area on the upper stalk. The spores are brown and elliptical.[1]
Its edibility is unknown, but it is not recommended due to its similarity to deadly poisonous species.[1]
Cortinarius infractus is a similar species that usually has a smaller cap.[1]
