Saprobic on dead wood mostly in freshwater habitats. Sexual morph: Ascomata immersed, brown, solitary or in small groups, papillate or with a rostrate neck. Ostiole periphysate. Peridium layered, with outer layer brown, inner layers hyaline. Paraphyses septate, hyaline. Asci 8-spored, unitunicate, cylindrical, with a J-, apical ring at the apex. Ascospores uniseriate, fusiform, hyaline or versicolorous, with brown middle cells and hyaline end cells, usually 5-septate, sometimes slightly constricted at the septa and sometimes guttulate. Asexual morph: Hyphomycetous. Colonies effuse or sporodochial, dark brown to black, scattered. Conidiophores macronematous or semi-macronematous, mononematous, branched or unbranched, hyaline, pale brown to mid brown. Conidiogenous cells monoblastic, globose to clavate, terminal, sometimes discrete. Conidia clavate, obovoid or obpyriform, septate, smooth, brown to dark brown; basal cell pale brown, trapeziform or triangular (adapted from Yang et al. 2016b).
Notes – The family concept was expanded to include Bactrodesmiastrum, Mucispora, Fuscosporella, Parafuscosporella and two sexual genera Plagiascoma and Pseudoascotaiwania (Boonyuen et al. 2016, Réblová et al. 2016c, Hernández-Restrepo et al. 2017, Hongsanan et al. 2017). Mucispora is characterized by macronematous conidiophores and obovoid dark conidia. The characters shared by Bactrodesmiastrum, Fuscosporella and Parafuscosporella are sporodochial conidiomata, monoblastic conidiogenous cells and brown septate conidia (Hernández-Restrepo et al. 2013, 2015a, Yang et al. 2016b). Plagiascoma and Pseudoascotaiwania represent the only known sexual morphs in the order characterized by cylindrical asci, with a J-, apical ring and fusiform ascospores (Fallah et al. 1999, Réblová et al. 2016c). The understanding of Fuscosporellales (Boonyuen et al. 2016, Réblová et al. 2016c, Yang et al. 2016b) requires further collections and molecular data.
Type species: Fuscosporella Jing Yang, Bhat & K.D. Hyde, in Yang, Maharachchikumbura, Bhat, Hyde, McKenzie, Jones, Al-Sadi & Yumlong, Cryptog. Mycol. 37(4): 457 (2016).
