Taxonomy

The fungus was first described to science in 1930 by German mycologist Julius Schäffer, who called it Galera aurea. Tsuguo Hongo transferred it to the genus Conocybe in 1963.[2] In 2000, Anton Hausknecht published the variety C. aurea var. hololeuca, but this taxon is not considered to have independent taxonomic significance by Index Fungorum.[3] The specific epithet aurea, meaning gold-coloured, refers to the fruitbody colour.

The species is related to Conocybe tenera.[4]

Habitat and distribution

Conocybe aurea is a saprobic fungus that prefers to grow in nitrate-rich soils, fields, woodchip mulch, old compost, and greenhouses. A rare but widespread species, it is found in Europe, Asia, North America, and South America.[5]

Description

The cap is orangish yellow, and up to 5 cm in diameter.[4] The gills and stipe are beige, the former browning with age.[4]

Toxicity

The toxicity is unknown. Related species are known to be toxic.[6]

Similar species

Conocybe apala is common, but with a whiter and more fragile conical cap.[4]
