Saprobic, hypersaprotrophic on stromata of Diaporthe in freshwater or terrestrial habitats. Sexual morph: Ascomata perithecial, scattered, aggregated or in groups, stromatic or astromatic, immersed to erumpent, globose, subglobose or ellipsoid, coloured, sometimes seated in a stroma or basal stroma. Neck or papilla centrally located, cylindrical, upright or slightly horizontal to the substrate, pale brown, dark brown to black. Ostiolum periphysate. Peridium leathery to fragile, twoor three-layered. Paraphyses abundant, persistent, septate. Asci 8-spored, unitunicate, cylindrical- or fusoid, with a distinctive, J-, apical ring. Ascospores uniseriate or overlapping uni-seriate, hyaline, globose, subglobose, ellipsoidal or fusiform, unicellular or septate, thin- or thick-walled, verruculose or smooth-walled, with or without a gelatinous sheath. Asexual morph: Coelomycetous, produced in culture with or without sporodochial conidiomata. Conidiophores aggregated, hyaline to subhyaline, with a clavate or penicillate head or conidiogenous cells developing from hyphae. Conidiogenous cells monoblastic or polyblastic, sympodially proliferating, terminal, cylindrical, hyaline. Conidia ellipsoid to obovoid, hyaline, aseptate, smoothwalled (adapted from Raja et al. 2003, Jaklitsch et al. 2013Réblová et al. 2014Zhang et al. 2017a)

Notes: Woswasiaceae was introduced by Zhang et al. (2017a) and placed in Diaporthomycetidae, families incertae sedis (Jaklitsch et al. 2013Réblová et al. 2014Senanayake et al. 2016Zhang et al. 2017a). The family presently contains three genera, Cyanoannulus, Woswasia and Xylochrysis. The family status was strongly supported in the MCC tree, which has a stem age at ca 115 MYA (Hyde et al. 2017aZhang et al. 2017a).

Type genus: Woswasia Jaklitsch, Réblová & Voglmayr.
