Saprobic on submerged decaying wood in freshwater habitats. Asexual morph: Undetermined. Sexual morph: Ascomata immersed, perithecial, subglobose to conical, dark brown to black, papillate, ostiolate, slit-like on host surface. Ascomatal wall coriaceous, composed of thick-walled, dark brown cells of textura angularis in the outer wall layer, becoming pale brown to hyaline cells of textura angularis towards inner layers. Pseudoparaphyses numerous, cellular, hyaline, branched, septate. Asci cylindrical to clavate, rounded at the apex, 8-spored, bitunicate, short pedicellate. Ascospores clavate, golden brown, multi-septate, slightly constricted at the septa, sometimes slightly curved.
