subglobisporus Blanco-Dios (1989) Leucocoprinus ianthinus is a species of mushroom producing fungus in the family Agaricaceae.

[2][3] Like several other Leucocoprinus species it may have originated in a tropical climate but now finds a home in plant pots, greenhouses and compost piles in many countries.

It was first described in 1888 by the English botanist and mycologist Mordecai Cubitt Cooke who classified it as Agaricus (Lepiota) ianthinus based on specimens collected in the hothouses of Kew Gardens (London, England) in 1888.

[7] In 1934 the French botanists and mycologists Roger Heim and Henri Romagnesi reclassified it as a variant of Hiatula cepaestipes (now known as Leucocoprinus cepistipes).

The surface is whitish with a dark purple to reddish brown centre and purplish scales spreading across the cap but becoming sparse at towards the edges.

Stem: 3.5-7cm long and 2-5mm wide tapering upwards from a slightly bulbous base and hollow interior.

[13] Ellipsoid to amygdaliform with a thick wall and a germ pore that is covered with a hyaline cap.
