Micropsalliota is a genus of small agaric fungi in the family Agaricaceae. The genus contains about 60 species, most of which are found in tropical areas.

Taxonomy[]

The genus was circumscribed by Austrian mycologist Franz Xaver Rudolf von Höhnel in 1914 with as the type species. This species was collected in 1907 by Höhnel in the Bogor Botanical Gardens in Bogor, Indonesia.^[1] The generic name refers to the similarity of the slender fruitbodies to those in Psalliota (a genus that has since been synonymized with Agaricus).^[2] Emendations were made to the genus in 1969 by Pegler and Rayner,^[3] and then in 1976 by Heinemann.^[4] Molecular phylogenetics has shown that the genus represents a monophyletic lineage in the family Agaricaceae that is sister to the genus Hymenagaricus.^[2]

Description[]

Micropsalliota fruitbodies have a ring on the stipe, free gill attachment, and brown spores. Micropsalliota is distinguished from similar genera with dark spore prints by its small- to medium-sized fruit bodies, ellipsoid to cymbiform (boat-shaped) basidiospores with an apical thickening in the endosporium, cheilocystidia that are often capitate (ending in a distinct compact head) or nearly so, and pileipellis hyphae encrusted with a pigment that turns olive to green after application of NH₄OH.^[2]

Ecology and distribution[]

About 40 Micropsalliota species have been described by Belgian mycologist Paul Heinemann and colleagues from the tropics of Africa, America, India, Indonesia, and Malaysia. Eleven new species from Thailand were added in 2010.^[2] is the first species of the genus reported from China.^[5]
