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]
