Taxonomy
Elias Magnus Fries described the species in 1838.[3]
Description
The cap is 4 to 13 centimetres (1+1⁄2 to 5 in) wide, orangish-brown, bun to bell-shaped then flattening out, and sometimes developing small scales.[2] The gills are tan when young, then rusty brown. They are somewhat close,[1] and shallowly sinuate. The spore print is rusty brown.[1]
The tannish stem is up to 15 cm (6 in) long and 2.5 cm (1 in) thick;[1][2] it is usually wider at the base and has 1–5 reddish bands.[1] The flesh is light brown[2] and its scent mild to radish-like.[1]
Similar species
It resembles C. bolaris,[1] C. boulderensis, C. haematochelis,[2] C. paragaudis, C. rubicundulus,[1] and C. subtestaceus.[2] Some species in the genus contain the mycotoxin orellanine, which can be deadly.[4]

Habitat and distribution
It can be found from August to September under birch trees in North America[1] (especially the northeast)[2] and in Europe.
Uses
The species has been considered edible and mediocre[5] to good, with caution advised to confirm its identification.[2] Some guides consider it inedible,[6] and it has been found to contain orellanine, though at much lower concentrations than the lethal webcaps.[4]
When dyeing cloths, without added metals, it discharges pink, with tin yellow, with copper green and with iron olivic dyes.
