Saprobic on decaying submerged intertidal mangrove wood. Sexual morph: Ascomata lying horizontal, immersed in substratum, subglobose to pyriform, solitary or gregarious, black, ostiolate. Peridium thin, composed of brown pseudoparenchymatous cells. Hamathecium comprising dense, thin, anastomosing, branching, trabeculate, pseudoparaphyses, embedded in a gelatinous matrix. Asci 8-spored, bitunicate, fissitunicate, cylindrical, long pedicellate. Ascospores overlapping 1- seriate, fusiform, dark brown, with hyaline rounded ends, 1–4-septate toward each end, aseptate in the centre, not constricted at the septa in the centre part, smooth-walled, releasing mucilage from the ends. Asexual morph: Pycnidia solitary or rarely confluent, on upper surface or submerged in agar, globose to subglobose or pyriform, with dark brown, septate mycelial outgrowths, papillate, ostiolate, olivaceous to olivaceous-black, the wall with pseudoparenchymatous cells.

Type – Biatriospora K.D. Hyde & Borse.
Notes – The monogeneric family Biatriosporaceae was established by Hyde et al. (2013) to accommodate a marine genus Biatriospora typified by B. marina (Hyde & Borse 1986) based on morphological and molecular data (Hyde et al. 2013).
