Leucocoprinus russoceps is a species of mushroom producing fungus in the family Agaricaceae.[1][2]
It was described in 1871 by the English botanists and mycologists Miles Joseph Berkeley and Christopher Edmund Broome who classified it as Agaricus (Lepiota) russoceps.[3]
In 1887 it was reclassified as Lepiota russoceps by the Italian mycologist Pier Andrea Saccardo[4] and then as Mastocephalus russoceps in 1891 by the German botanist Otto Kunze,[5] however Kunze's Mastocephalus genus, along with most of 'Revisio generum plantarum' was not widely accepted by the scientific community of the age so it remained a Lepiota.
In 1987 it was reclassified as Leucocoprinus russoceps by the mycologist Jörg Raithelhuber.[6]
Leucocoprinus russoceps is a small dapperling mushroom.
Cap: 1.5-2.5cm wide starting campanulate before flattening and expanding to convex. The surface is yellow-brown to ochre with a pulverulent, powdery coating and striations from the edges. Gills: Pale, 'almost free' and close. Stem: 4cm long and 1.5mm thick at the top with a claviform taper to 4mm wide at the base. The surface is paler than the cap sometimes with a slight greenish tint with age whilst the interior is stuffed with white flesh. The stem ring may disappear. Spores: Smooth, ovate to elliptic with a faint germ pore. 7.2-9 x 4.2-4.6µm.[6]
The specimens were found growing on the ground in forests in Brazil.[6]
The specimens studied by Berk and Broome were found on the ground in June 1860 in Ceylon (now Sri Lanka).[3]
