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.
The genus was circumscribed by Austrian mycologist Franz Xaver Rudolf von Höhnel in 1914 with Micropsalliota pseudovolvulata 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]
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]
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] Micropsalliota pseudoglobocystis is the first species of the genus reported from China. [5] A new species Micropsalliota albofelina was described in 2021, it is also the first record of this genus in Vietnam. [6]
As of July 2022 [update] , Index Fungorum accepts 70 species of Micropsalliota:
Tylopilus is a genus of over 100 species of mycorrhizal bolete fungi separated from Boletus. Its best known member is the bitter bolete, the only species found in Europe. More species are found in North America, such as the edible species T. alboater. Australia is another continent where many species are found. All members of the genus form mycorrhizal relationships with trees. Members of the genus are distinguished by their pinkish pore surfaces.
Macrolepiota is a genus of white spored, gilled mushrooms of the family Agaricaceae. The best-known member is the parasol mushroom (M. procera). The widespread genus contains about 40 species.
Boletellus is a genus of fungi in the family Boletaceae. The genus has a widespread distribution, especially in subtropical regions, and contains about 50 species. The genus was first described by American mycologist William Alphonso Murrill in 1909. The genus name means "small Boletus".
Splanchnonema is a genus of fungi in the family Pleomassariaceae. The genus was circumscribed in 1829 by August Carl Joseph Corda. One of the species, Splanchnonema lichenisatum, is a lichen.
Phylloporus is a genus of fungi in the family Boletaceae. The genus has a cosmopolitan distribution, and contains about 50 species, mostly in tropical areas.
Cystoderma is a genus of fungi in the family Agaricaceae or Cystodermataceae. Its family position is in doubt and the family "Cystodermataceae" and tribe "Cystodermateae" have been proposed to include this group following recent molecular work.
Cystolepiota is a genus of mushroom-forming fungi in the family Agaricaceae.
Hymenagaricus is a genus of fungi in the family Agaricaceae. The widespread genus contains species found largely in tropical regions. Hymenagaricus was circumscribedby Belgian mycologist Paul Heinemann in 1981.
Coniolepiota is a fungal genus in the family Agaricaceae. The genus is monotypic, containing only a single species, Coniolepiota spongodes. It was first described from Thailand, and later also reported from Bangladesh and China. The species has also been observed in Malaysia, Singapore, Cambodia, Indonesia, Taiwan, Philippines, and South Africa.
Astraeus odoratus is a species of false earthstar in the family Diplocystaceae. Described as a new species in 2004, it was originally found in the Thai highlands growing in sandy or laterite-rich soil in dry lowland dipterocarp forests. The species is found in Southeast Asia.
Dictyosporium is the type genus of fungi belonging to the family Dictyosporiaceae. By an estimate in 2018 it is formed by 45 species.
Evan Benjamin Gareth Jones is a British mycologist. His main area of research interest is aquatic fungi, particularly marine fungi. He has supervised about 100 PhD and MSc students, published approximately 600 research articles and is a highly cited scientist. Other research interests include marine biofouling, biodeterioration of materials, and wood decay by fungi.
Dennis Edmund Desjardin is an American mycologist. He has been called the "Mushroom Guru of the West Coast".
