Cyptotrama nivea also known as Cyptotrama niveum is a species of mushroom producing fungus in the family Agaricaceae.[1][2]
Taxonomy[edit]
It was described in 1989 by the German mycologist Rolf Singer who classified it as Cyptotrama niveum[3] however this is now regarded as an orthographic variant and the species is now called Cyptotrama nivea.[2]
Description[edit]
Cyptotrama nivea is a very small snow white mushroom with white, unchanging flesh.[3]
Cap: 5mm wide and obtusely convex. The surface is snow white and finely frosted (pruinose) or finely hairy/woolly (sub-tomentose). Gills: Subdecurrent to decurrent, moderately crowded and white. Stem: 1.6cm wide and 1.3mm thick, running equally along the length. The surface is white with a silky, downy coating and a tomentose base. Spores: Ellipsoidal, smooth, hyaline, non-amyloid. 10.5-16.8 x 6.7-9.3 μm. Basidia: 25-31 x 8-13 μm. Four spored. Smell: Indistinct.[3]
Etymology[edit]
The specific epithet nivea or niveum derives from the Latin niveus meaning as white as snow.[4]
Habitat and distribution[edit]
The specimens studied by Singer were found growing solitary on fallen leaves in Igapó forests along the Igarapé Tarumãzinho river in Brazil.[3]
