Saprobic on submerged decaying wood in freshwater habitats. Sexual morph: Ascomata 230– 270 μm high, 180–220μm diam (x̄ = 238 × 203 μm, n = 5), semi-immersed, coriaceous, black, subglobose, ostiolate. Ostiole rounded or slit-like, variable in shape, central, periphysate, with a pore-like opening. Peridum 25–40 μm wide, comprise two strata, outer stratum comprising brown to dark brown flattened cells, inner stratum comprising several layers of hyaline cells of textura angularis. Hamathecium comprising 1.5–2.0 μm wide, septate, cellular Pseudoparaphyses, filiform, septate with small guttules, hyaline. Asci 47–54 × 6.5–8.5 μm (x̄ = 50 × 7.5 μm, n = 20), 8- spored, bitunicate, cylindrical, round at the apex, short pedicellate, with an indistinct ocular chamber. Ascospores 12–13 × 3–4 μm (x̄ = 12 × 3.5 μm, n = 30), biseriate, overlapping, fusiform with acute ends, hyaline, straight or slightly curved, 1-septate, strongly constricted at the septum, mostly 4- guttules, smooth-walled, with hyaline appendages at both ends. Asexual morph: Undetermined. (Descriptions from Bao et al. 2019)
