Elias Magnus Fries described the species in 1838.[1]

The cap is bell shaped at first, later flattening out, vividly rust-brown becoming slightly paler with age, with small fibrous scales. The cap grows from 5 to 15 cm in diameter. The gills are dark rust-brown; broad, distant and shallowly sinuate. The spores are also rust-brown. The flesh is light brown.

Use

The species is inedible.[2] The fruit body has been found to contain orellanine, though at much lower concentrations than the lethal webcaps.[3]

When dyeing cloths, without added metals, it discharges pink, with tin yellow, with copper green and with iron olivic dyes.
