Leucocoprinus discoideus is a species of mushroom producing fungus in the family Agaricaceae. [1] [2] In the local language when the mushroom cap is open it is known as batakania or bepokua pembe when it is immature with a closed cap. [3] However 'bepokua' may also be used to refer to other similar looking mushroom species such as Micropsalliota bambusicola. [4]

Taxonomy

It was first described in 1936 by the Belgian mycologist Maurice Beeli who classified it as Lepiota discoidea, [5] whilst illustrations of the mushrooms were produced by Mme M. Goossens-Fontana. [6]

In 1977 it was reclassified by the Belgian mycologist Paul Heinemann who classified it as Leucocoprinus discoideus. [7] [3]

Description

Leucocoprinus discoideus is a small dapperling mushroom with whitish flesh which discolours pinkish brown.

Cap: 3-6cm wide with a white, campanulate (bell shaped) to conical cap and a slight brown umbo. It is covered in small brownish ochre scales which are concentrated on the centre disc or umbo and sparsely scattered on the rest of the cap surface. The cap edges have striations which extend about half way across the cap. Gills: Free, crowded and white. Stem: 7-8cm tall and 4-5mm thick with a hairy (tomentose) coating. It is hollow, white and discolours pale pinkish brown with age. The fragile, membranous stem ring is white and located towards the top of the stem. Spore print: White. Spores: Ellipsoid with a pore. (8.1)9.1-11.3 × (5.7)6.3-7.3 μm. Taste: Bitter. When dry it discolours light brown. [6] [3]

Habitat and distribution

L. discoideus is scarcely recorded and little known. The specimens studied by Heinemann were found in the forest of the Eala region in Zaïre (now the Democratic Republic of the Congo). They were growing in a dense group on a dead tree trunk and on the ground in a dry forest area. [8] Additional specimens were found near Lubumbashi in the South of the country and found growing on decomposing coffee in a plantation near lake Edward and lake Kivu to the North East. [3]

It was also recorded growing in a potted plant in a greenhouse at the Meise Botanic Garden in Belgium. [9]

Cantharellus luteopunctatus is a species of fungus in the genus Cantharellus. Found in Africa, it was described as new to science in 1928 by Belgian mycologist Maurice Beeli as Lentinus luteopunctatus. Paul Heinemann transferred it to Cantharellus in 1958.

<i>Leucocoprinus cretaceus</i> Species of fungus

Leucocoprinus cretaceus is a species of mushroom producing fungus in the family Agaricaceae. It is likely tropical in origin although it was first documented in Europe where it was often found growing in greenhouses and bark beds. However many early observations conflate this species with Leucocoprinus birnbaumii or Leucocoprinus cepistipes despite sharing only some superficial similarities. This fungus is quite versatile even for a saprotroph and is often found growing in clusters on woodchips, sawdust and compost heaps as well as directly from the ground or on trees. It may also appear in plant pots and greenhouses in colder countries in which it is not well equipped to survive outside.

<i>Leucoagaricus badhamii</i> Species of fungus

Leucoagaricus badhamii is a species of fungus in the family Agaricaceae and genus Leucoagaricus. The flesh of this mushroom turns blood red when cut or bruised, hence its common name of blushing dapperling. These damaged areas may eventually turn brown or black and likewise the mushroom may discolour brown or black with age. All parts of the flesh display red staining aiding in identification.
