The cap is red-brown, tawny-brown to brown ochre, conical then expanded, with a central umbo; its margin is inrolled a long time, hairy, fluffy-woolly, overhanging. The cap surface is covered with small upturned, fluffy and concentric scales, denser towards the centre, clearly marked at the margin, dry, not viscid nor sticky.

The stem is whitish, with red-brown fibrils from the base up giving it a paler brown shade than the cap, cylindrical and hollow, fragile, without ring, possibly with some cortina-like remnants on the stem.

The flesh is white, rosy in stem base, turning pink when exposed to air, especially in stem and gills; its taste is bitter; the odour is earthy or mealy when cut; its texture is fibrous.

The gills are white to cream, then stained with rust with age, emarginate to adnate, rather distant (nb of gills per 90° ~ 26 ). The spore print is white. This species is mycorrhizal. It grows on the ground, in coniferous woods, forest edges and rather in the mountains, more rarely in deciduous woods, on a rather calcareous soil, with spruce, pine.

The fruiting period takes place from July to December.
