Classification: Pleosporales, Pleosporomycetidae, Dothideomycetes, Pezizomycotina, Ascomycota, Fungi

Saprobic on decaying wood. Sexual morph: Undetermined. Asexual morph: hyphomycetous, dictyosporous. Colonies on natural substratum sporodochia, superficial, compact, scattered, irregular, dark-brown to black, glistening. Mycelium immersed in the substrate, septate, branched. Conidiophores micronematous, mononematous, reduced, hyaline. Conidiogenous cells holoblastic, monoblastic, integrated, terminal, determinate. Conidia acrogenous, solitary, broadly ellipsoidal to obovoid, brown, olivaceous green, muriform, guttulate, smooth-walled, with or without guttules, usually with conidiogenous cell attached (adapted from Hyde et al. 2019).

Notes :Berkleasmium is considered as polyphyletic (Pinnoi et al. 2007, Hu et al. 2010, Lu et al. 2018). The type species of Berkleasmium has been moved to Tubeufiales (Tanney & Miller 2017, Lu et al. 2018). The family was introduced by Hyde et al. (2019) to accommodate a berkleasmium-like hyphomycete which formed a clade related to Hermatomytaceae within Pleosporales (Hyde et al. 2019).

Type genus: Pseudoberkleasmium Tibpromma & K.D. Hyde.
