Overview of the European species of the genus (, ) with notes on extralimital taxa.

A revision, based on morphological and multigene analysis, of the species currently present in Europe is provided. Portions of nrITS rDNA, nr28S rDNA (LSU), RNA polymerase II second largest subunit (), translation elongation factor 1-alpha (), and ATPase subunit 6 (), were used to sort out the relationships of the species within the genus. Three subgenera were recognized: subg. encompassing . , . , . , . , . and the new species . from Switzerland; the new subg. including . and . ; and the new subg. for accommodating , a peculiar entity characterized by a pleurotoid habit and growing on decaying, abandoned termite nests in the Dominican Republic. originally described from China is here reported and described for the first time in Europe (Italy and Estonia). and are reduced to later synonyms of ; similarly, is treated as a later synonym of while and of . Finally, Austrian and Swedish herbarium collections identified as , a doubtful taxon considered by several modern authors occasionally as either a similar but distinct species from . or as a dwarfish, puny and odourless form of , have been proved to be , a species recently described from Turkey and Estonia, and also later reported from Italy and USA. : Vizzini A, Consiglio G, Marchetti M. 2023.
