Berkleasmium Zobel, Icon. fung. (Prague) 6: 4 (1854).

Index Fungorum number: IF 7362; Facesoffungi number: FoF 01879; 44 morphological species (Species Fungorum 2020), 7 species with molecular data.

Type species: Berkleasmium concinnum (Berk.) S. Hughes, Canad. J. Bot. 36: 740 (1958).

≡ Sporidesmium concinnum Berk., London J. Bot. 4: 309 (1845).

Notes: Tanney and Miller (2017) accepted Berkleasmium within Tubeufiaceae, and reported that the type species B. concinnum, is the asexual morph of Neoacanthostigma septoconstrictum based on phylogenetic analyses. Lu et al. (2018b) accepted seven Berkleasmium species within Tubeufiaceae based on phylogenetic and morphological evidence. Berkleasmium is characterized by superficial ascomata with dark brown to black multi-celled setae, and cylindrical asci with slightly curved fusiform ascospores (Tanney and Miller 2017; Lu et al. 2018b). Its asexual morphs comprise dictyosporous and helicosporous hyphomycetes (Tanney and Miller 2017; Lu et al. 2018b).
