The description taken from Liu et al. (2015)

Saprobic on dead herbaceous branches. Sexual morph: Ascomata 100–150 μm high × 100–175 μm diam. (x̄ = 142.2 × 131.2 μm, n = 10), solitary, scattered, immersed to erumpent, globose or subglobose, dark brown to black, coriaceous, ostiolate. Ostiole 30–70 μm high 20–30 μm diam. (x̄ = 48.7 × 23.8 μm, n = 10), blackish-brown, smooth, ostiolar canal filled with dark brown cells. Peridium 10–15 μm wide at the base, 8–12 μm wide at the sides, composed with reddish to dark brown cells of textura angularis. Hamathecium comprising numerous, 1.5–2.5 μm (n = 30) wide, filamentous, branched, septate, pseudoparaphyses. Asci 60–90 × 10–20 μm (x̄ = 69 × 14.6 μm, n = 40), 8-spored, bitunicate, fissitunicate, cylindricclavate to clavate, pedicellate, thick-walled at the apex, with minute ocular chamber. Ascospores 15–20 × 5–8 μm (x̄ = 18.2 × 6.3 μm, n = 50), overlapping 1–2-seriate, ellipsoidal to subfusiform, upper part wider than the lower part, muriform, 3–5 transversely septate, with 1–3 vertical septa, constricted at the central septum, initially hyaline, becoming yellowish-brown at maturity, ends remaining lighter and cone-shaped, with rounded ends, without a mucilaginous sheath.
