Hiatulopsis aureoflava is a species of mushroom producing fungus in the family Agaricaceae.[1][2]

Taxonomy

It was described in 1989 by the German mycologist Rolf Singer who classified it as Hiatulopsis aureoflava.[3]

Description

Hiatulopsis aureoflava is a very small golden yellow mushroom with white flesh.[3]

Cap: 7-11mm wide and ovate to campanulate. The surface is golden with a fine, dense coating of flocculose (woolly) scales and the margins are yellow. Some scales may be removed by rain. Gills: Free to sub-free, crowded and whitish. They are narrow and ascending. Stem: 3.6cm tall and 1.8mm thick tapering to a 4mm wide base where white mycelium may be present but sclerotia are not observed. The surface is yellowish with woolly to powdery scales (flocculose-pulverulent) with a golden base with a tomentose coating. There is no ring or volva. Spores: Ellipsoidal without a germ pore, hyaline, non-amyloid. 7-10 x 5.5-6.5 μm. Basidia: 22-34 x 11-13 μm. Four spored. Smell: Indistinct.[3]

Etymology

The specific epithet aureoflava derives from the Latin aureo meaning golden and flava meaning yellow.[4]

Habitat and distribution

The specimens studied by Singer were found growing solitary or gregariously on the ground in the tropical forests of Brazil, 30km North of Manaus.[3]
