(Bull.) Vilgalys, Hopple, & Johnson
Taxon 50(1): 234. 2001.
Cap 2-5 cm broad, cylindrical to oval, becoming conic, finally campanulate; yellow-brown, conspicuously striate to corrugate, covered with evanescent glistening granules; margin becoming torn, sometimes upturned in age, deliquescing towards the center; flesh thin, soft, white.
Gills notched, close, white turning pinkish, finally black.
Stipe 1.5-5 cm long, 2-5 mm thick, white, hollow, equal; veil absent.
Spores 7.5-10 x 3-5 µm, elliptical, smooth with an apical germ pore. Spore print black.
Typically fruiting in cespitose clusters near stumps or rotting wood, from fall through spring.
Edible, of good flavor, but little texture.
gets its common name from the glistening particles that cover the young, developing caps. These soon wash or wear off. However, it is still easily recognized by the yellow-brown caps, clustered fruiting habit, deliquescing gills, and tendency to fruit near rotting wood.
is a larger mushroom, which also tends to fruit in clusters, but it has a silky grey-brown cap.
