Saprobic on decaying wood in freshwater and terrestrial habitats. Sexual morph: Ascomata astromatic, perithecial, solitary to small groups, immersed to superficial, subhyaline to pale brown or dark brown to black, upright or obliquely lying, papillate or with a long cylindrical neck, sometimes hairy, ostiolate, periphysate. Peridium soft-textured, leathery to fragile, two-layered, inner layer of hyaline, elongated cells, outer layer partly carbonaceous. Paraphyses abundant, persistent, cylindrical, septate, tapering, longer than asci. Asci 8-spored, unitunicate, cylindricalclavate, pedicellate, with a J+, or J-, apical ring. Ascospores uni- to biseriate, smooth-walled, fusiform, hyaline, cylindrical to cymbiform, slightly falcate, multi-septate, without appendages or mucilaginous sheath, with or without guttules. Asexual morph: Undetermined (adapted from Réblová et al. 2010, 2015a).

Notes: Based on morpho-molecular data, Pisorisporiaceae was introduced by Réblová et al. (2015a) in Pisorisporiales. The family predominantly includes aquatic fungi and few terrestrial taxa in Achroceratosphaeria and Pisorisporium. In the phylogenetic analysis, the two genera cluster in a sister clade. However, the genera differ in ascomata and presence of a J+, apical ring in the asci: Achroceratosphaeria has hyaline to pale brown ascomata and a J-, apical ascus ring, while Pisorisporium has carbonaceous ascomata with a J+, ascal apical ring (Réblová et al. 2015a, 2016c). The apical ring colouration reactions found with Pisorisporium spp. are commonly encountered in genera with chitinoid apical rings (Réblová et al. 2015a). Distribution of the family is limited to countries in Europe and Asia (Maharachchikumbura et al. 2016b).

Type genus: Pisorisporium Réblová & J. Fourn.
