Candolleomyces candolleanus, also known as the Pale Brittlestem, is a moderately sized agaric with a cap whose colour varies from white to golden brown. The margin is often irregular and radially asymmetrical, which is a defining characteristic of this species. The mushroom typically grows tufted on soil near broad-leaf trees, as well as on stumps and other woody debris.

Cap starts rounded-conical or convex, later becoming broadly convex, bell-shaped, or nearly flat. It often develops shallow radial wrinkles and is dry. The cap is initially honey-yellow but changes to pale brownish or nearly white as it dries out. The flesh is white and thin. Gills at first pallid grey with liliaceous tinge, grey- to chocolate-brown as mature, adnate or adnexed, crowded. Stem white, fragile, hollow and smooth, sometimes with loosely clinging partial veil remnants in a ring-like zone. Spore print dark purplish brown.

Microscopic Features: The spores are ellipsoidal, smooth, measuring 6.5-9.5 x 4-5μm, and have a germ pore.

Synonyms: Candolleomyces candolleanus was previoisy named Psathyrella candolleana.
