Saprobic on dead herbaceous branches in terrestrial habitats. Sexual morph: Ascomata 190–275 µm high 150–250 µm diam. (x̅ = 232.4 × 212.7 µm, n = 10), globose to subglobose, solitary, dark brown to black, immersed, substrate stained purple, fused to the host tissue, ostiolate. Ostiole 50-65 µm high 30–60 µm diam. (= 57.8 × 50.2 µm, n = 5) short to papillate, black, smooth, ostiolar canal filled with periphyses-like structures. Peridium 9–14 µm wide at the base, 15–20 µm wide at the sides, comprising 3–4 layers of brown to reddish brown cells textura angularis, with inner 1–2 layers of cells thin–walled and hyaline. Hamathecium comprising numerous, 1–2 µm (n = 30) wide, filamentous, branched, septate, pseudoparaphyses. Asci 120–135 × 18–23 µm ( = 129.9 × 20.9 µm, n = 40), 8-spored, bitunicate, fissitunicate, cylindric-clavate, short pedicellate, thick-walled at the apex, with a minute ocular chamber. Ascospores 30–35 × 10–12 µm (= 34.4 × 10.7 µm, n = 50), overlapping 1–2-seriate, golden yellow turning brown when mature, fusiform, assymetrical with one side flattened, muriform, with 1–2 longitudinal septa in all cells and rarely in end cells, slightly constricted at the middle septum, conical and narrowly rounded at the ends, surrounded by a mucilaginous sheath. Asexual morph: Undetermined.
