Saprobic on decaying, submerged twigs in freshwater habitats. Asexual morph: Undetermined. Sexual morph: Ascomata on the host 164–361.5 × 246.5–460.5 μm, scattered, immersed to partially erumpent, black, globose or subglobose, glabrous, with papilla visible as raised, dark spots on host surface, ostiole central. Peridium 13.5–32.5(–86.5) μm thick, composing several layers of pseudoparenchymatous cells, arranged in a textura angularis, pigmented at the outer part. Hamathecium comprising numerous, 1.3−2.3 μm wide, hyaline, septate pseudoparaphyses, embedded in a mucilaginous matrix, rarely anastomosing between and above the asci. Asci 99–130 × 16–22 μm ( = 113.5 × 18.5 μm, n = 20), cylindric-clavate, pedicellate, apically rounded, with an ocular chamber, bitunicate, 8-spored. Ascospores 26.5–34 × 7–10.5 μm (= 28.8 × 8.5 μm, n = 30), 1-euseptate, slightly constricted at the septa, thin-walled, hyaline to subhyaline, smooth, broadly fusiform, 2-3-seriate, with 4-5 refractive globules, sometimes with a mucilaginous sheath.
