Type – Pseudoberkleasmium Tibpromma & K.D. Hyde.
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).
