Arthrosporella is a fungal genus in the family Tricholomataceae. It is a monotypic genus, containing the single species Arthrosporella ditopa, found in South America. The genus was described by mycologist Rolf Singer in 1970. [2]

Contents

Singer originally described the single species in 1950 [3] for an agaric he and a colleague had collected in Tucumán Province, Argentina. He placed the new species in the genus Armillariella, which he considered to be the correct name of Armillaria . However, he later came to realize that the species was unusual due to being found with joint teleomorphic and anamorphic forms, both of which produced arthrospores (a type of conidiospore). [4] Thus he erected a new genus for the species in his 1970 treatment of tribe Omphalinae for the Flora Neotropica series, also describing its anamorph as Nothoclavulina ditopa . [2] The species and genus remain known from only the type collection, and more specifically the Nothoclavulina, the agaricoid half having been lost. [4]

In 2005, it was announced that new species had been discovered that belonged to the genus, [5] but further study indicated that they represented separate genera not closely related to Arthrosporella (as was first thought), and they were described in 2007 as Arthromyces and Blastosporella , the former in the Tricholomataceae, the latter in the Lyophyllaceae. [4]
