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).
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.
