Etymology.

The family name refers to the type genus.

Type genus.

Xenoberkleasmium N. G. Liu, Jian K. Liu & K. D. Hyde .

Description.

Sexual morph: Undetermined. Asexual morph: Hyphomycetous. Colonies on natural substratum effuse, scattered, punctiform or powdery, dark-brown to black, glistening. Mycelium partly immersed, partly superficial, composed of branched, septate, hyaline to pale brown hyphae. Conidiomata sporodochial. Conidiophores micronematous to macronematous, mononematous, sometime reduced to conidiogenous cells. Conidiogenous cells blastic, integrated, terminal, determinate. Conidia acrogenous, broadly ellipsoidal to obovoid, thick-walled, muriform, brown to olivaceous green, with or without guttules, usually with basal cell attached.

Notes.

Xenoberkleasmiaceae is introduced to accommodate the genus Xenoberkleasmium , which is characterized by sporodochial conidiomata and muriform, brown conidia. This group forms a distinct and well-supported clade within Pleosporales and shares a close relationship with the morphologically unrelated family Hypsostromataceae .
