The cap is dark ochre-brown, hygrophanous, becoming pale ochre when drying, conical or bell-shaped at first, then convex-expanded, sometimes bluntly umobnate; its margin is sulcate-grooved up two thirds toward centre when young or damp, later smooth. The cap surface is smooth, matt, non viscid, hygrophanous.

The stem is white to cream at the top, progressively grey-brown to rust towards base, fragile and slightly pruinose, without ring, and with white mycelial fibrils at its base, without ring.

The flesh is ochre, unchanging; its taste is faint or not distinctive; the odour is not distinctive; its texture is fibrous.

The gills are clay-ochre then ochre-brown to bright rusty-brown, free, ascending to narrowly adnate, with a flaky slightly paler edge, loosely crowded . The spore print is brown. This species is saprophytic. It grows on the ground, in grassy areas, meadows, gardens, greenhouses, also in forests according to some authors, on a rather rich, neutral to calcareous soil.

The fruiting period takes place from April to November.
Dimensions: width of cap approximately 1.5 cm (between 1 and 2 cm)
  height of stem approximately 5 cm (between 3 and 7 cm)
