It grows solitary or scattered in small tufted groups in damp mossy grassland, in coniferous forest clearings, or on wooded heaths.

Gills initially white, becoming creamy later. They are adnexed (narrowly attached to the stem), and initially quite crowded. Spore print is white. Stem cylindrical, and has a flaky-granular sheath beneath a fleeting, powdery ring. Flesh dirty yellow, firm and stuffed.
