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

Taxonomy

It was first described in 2018 by the French mycologists Vincent Lagardère & Guillaume Eyssartier from specimens found in 2017 in Mouréou, Arengosse in the South West Landes region of France. It was noted to be similar in appearance to Leucocoprinus cygneus with previous observations likely being confused with this species however it is differentiated from it by the grey flaky cap whilst L. cygneus is described as pure white and powdery. [3]

Description

Leucocoprinus griseofloccosus is a small dapperling mushroom with thin white flesh.

Cap: Up to 1 cm. Quickly opens to convex with a very slight white or greyish umbo. Stem: 0.5-1.5 x 0.1-0.2 cm. Wider at the base. White with a thin stem ring that is tinged with grey at the edges. Gills: White, crowded, free with a powdery edge. Spores: Elliptical with a tiny germ pore. Dextrinoid. 5.5 - 6.3 x 3.3 - 3.8 μm. Smell: Faint. [3]

Habitat and distribution

The specimens in France were found growing within rotting alder trunks beside a stream in mixed woodland. The woodland was located on clay rich soil within an ericaceous heath. [3]

In November 2019 it was found in the UK for the first time with specimens observed to be growing in rotten Douglas fir logs at the New Forest Reptile Centre near Lyndhurst, South Hampshire. Another observation was made in October 2020 on rotting pine logs in Marlhill copse near Southampton airport. [4]

Etymology

The specific epithet griseofloccosus is derived from the Latin griseus meaning grey and floccosus meaning flaky. This is a reference to the colour and texture of the veil. [3]

<i>Leucocoprinus</i> Genus of fungi

Leucocoprinus is a genus of fungi in the family Agaricaceae. Its best-known member is the distinctive yellow mushroom Leucocoprinus birnbaumii, which is found in plant pots and greenhouses worldwide. The type species is Leucocoprinus cepistipes. The genus has a widespread distribution and contains over 80 recognised species, however many of these species are very scarcely recorded and little known with only a small number of Leucocoprinus species which are commonly observed. The majority of the species in this genus are exclusive to tropical environments however numerous species have become a common sight in plant pots and greenhouses resulting in them becoming well known worldwide.

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

Leucocoprinus cepistipes, is a species of fungus in the family Agaricaceae. It is typically found on wood debris, such as wood chips but may also grow in potted plants or greenhouses. Typical characteristics include a fine-scaled bell-shaped cap, a partial veil, and a tendency to bruise a yellow to brown when handled.

Leucocoprinus straminellus is a species of mushroom producing fungus in the family Agaricaceae. Like 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. Leucocoprinus straminellus is described as being similar to the more commonly known Leucocoprinus birnbaumii but it is smaller and a lighter shade of yellow with smaller spores that lack a germ pore. It is also described as being superficially similar to Leucocoprinus fragilissimus but slightly more robust with flesh that is less translucent.
