Lepiota revoluta Rick (1937)

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

Taxonomy

[edit]

It was described in 1937 by the mycologist Johannes Rick who classified it as Lepiota revoluta.[3] Rick also noted a possible similarity to Lepiota spodolepsis as classified by Berk. & Broome however this species is not recorded in Species Fungorum or Mycobank and no citation is given for the text in which it may have been described.[3]

In 1987 it was reclassified as Leucocoprinus revolutus by the mycologist Jörg Raithelhuber.[4]

Description

[edit]

Leucocoprinus revolutus is a small dapperling mushroom.

Cap: 8-13mm wide starting hemispherical before expanding and curving upwards with a small umbo. The surface is grey-blackish with striations from the margins and the cap flesh is membranous or fibrous. Gills: White, moderately densely spaced, bulging with smooth edges. Stem: 2 cm long and 2mm wide, stiff and filamentous. The surface is pale and smooth with a whitish ring. Spores: Raithelhuber described the spores as 'Oval, smooth. 7–8.1 x 4.4-5.2 μm.'[4] However the spore size given by Rick is 5-6 x 3-4 μm.[3]

Etymology

[edit]

The specific epithet revolutus is Latin for rolled backward.[5] This is in reference to the description of the cap shape given in Latin by Rick of 'hemisphaerico-revoluto'.

Habitat and distribution

[edit]

The specimens were found growing on the ground in Brazil.[4]
