Conservation Status: Not of concern

Identification Notes:

The residual Collybia is made up of three very small (caps up to about 20 mm (0.8 in.)) species: C. cirrhata without sclerotia, usually associated with decaying mushrooms; C. cookei (Bresadola) Arnold, arising from yellow, irregularly shaped sclerotia, sometimes with decaying mushrooms but also in soil and litter; and C. tuberosa (Bulliard: Fries) P. Kummer, with reddish brown, apple seed-like sclerotia, usually associated with decaying mushrooms. All have minute to small, whitish, convex to flattened caps, narrow white gills, and thin whitish stipes that are often hairy below or have white strands associated with the sclerotia or substrate. The spores are white, small, smooth, and non-amyloid. These fungi are common, often in large troops, throughout western forests.
