Clitocybe robusta is a medium-sized to large (but not giant) white species with a cap that does not become deeply vase-shaped; in fact the caps are often distorted as a result of the clustered growth habit. Its spore print is pale yellowish, and it has a sickly, foul odor. Other identifying features include the inrolled cap margin, the broadly attached gills, and microscopic features (see below).
Ecology: Saprobic; growing in dense clusters under hardwoods or conifers, often on disturbed ground (along road banks and paths, etc.); summer and fall; widely distributed in North America.
Cap: 3-17 cm; convex, flat, shallowly depressed, or irregular and distorted; dry; satiny; white to dirty buff; the margin inrolled at first and later wavy.
Gills: Broadly attached to the stem or beginning to run down it; close or crowded; white or buff.
Stem: 4-10 cm long; up to 3.5 cm thick; more or less equal, or enlarged downwards; dry; fairly smooth, or with tiny fibers; white to cream.
Flesh: White; thick.
Odor and Taste: Sickly sweetish-foul.
Chemical Reactions: KOH on cap surface negative.
Spore Print: Pale yellowish.
Microscopic Details: Spores 5-8 x 3-5 µ; more or less elliptical; smooth; inamyloid. Cystidia absent. Clamp connections present.
Clitocybe alba is a synonym. According to some authors (e.g. Kuyper, 1995), Clitocybe nebularis var. alba is also a synonym; see the linked page for more information.
