Trichoglossum hirsutum is a species of fungi in the family Geoglossaceae. They are commonly called black earth tongues.

Description[]

Trichoglossum hirsutum makes a black club shaped fungus 3–8 cm high. The cap is usually 1–2 cm tall.[1] The spores are produced on the enlarged upper part, which is 5–8 mm wide, up to 2 cm high, flattened, spearhead-shaped to ellipsoid and finely velvety. The flesh is thin, tough and brownish. The stem is up to 6 cm long and 1–4 mm thick, cylindrical and velvety.[1] Spores are 80–195 x 5–7 micrometers, cylindric-clavate, broadest in the middle and tapering to the blunt ends, with 15 septa. The asci each have 8 spores. The paraphyses are brown, cylindrical and coiled at the tips.[2]

The species is inedible.[1]

Systematics[]

Trichoglossum hirsutum was first described as Geoglossum hirsutum in 1797 by Persoon. In 1907, Jean Louis Émile Boudier published it as Trichoglossum hirsutum.[3]

The epithet hirsutum (Latin: 'hairy tongue') refers to the fine hairs that cover the fruit body.[4]

Location[]

Trichoglossum hirsutum is found in woodlands in North America, Europe, Macaronesia[5] and Africa.[6] It is listed as an endangered species in Lithuania.[7]

Similar species[]
