Saprobic on submerged decorticated woody debris in aquatic habitats. Sexual morph: Ascomata immersed, becoming erumpent, solitary to gregarious, appearing as a black, oval to circular, shallow, subglobose, ostiolate. Peridium comprising several layers of small pseudoparenchymatous cells, arranged in a textura angularis, fusing at the outside with the host cells. Hamathecium comprising, densely, septate, cellular pseudoparaphyses, embedded in a gelatinous matrix. Asci 8-spored, bitunicate, fissitunicate, broadly clavate, pedicellate, rounded at the apex, with a wide, shallow, ocular chamber. Ascospores overlapping 2–3-seriate, ellipsoidal, hyaline, 1-septate, slightly constricted at the septum, with or without appendages. Asexual morph: Undetermined.
Notes: Wicklowiaceae was proposed by Ariyawansa et al. (2015a) to place monotypic freshwater ascomycetous genus Wicklowia in order Pleosporales based on both morphology and phylogeny. Wicklowiaceae shows close phylogenetic relationship to Lindgomycetaceae, but can be separated from all known freshwater ascomycetous genera by its subglobose, immersed to erumpent, black ascomata, with cellular pseudoparaphyses in a gelatinous matrix and broadly clavate asci, bearing cylindrical, hyaline, uni-septate ascospores surrounded by a gelatinous sheath.
Type genus: Wicklowia Raja, A. Ferrer & Shearer
