Index Fungorum number: IF 829711; Facesoffungi number: FoF 08328, 1 morphological species (Species Fungorum 2020), 1 species with molecular data.

Saprobic on dead herbaceous branches. Sexual morph: Ascomata solitary, scattered, immersed to erumpent, obpyriform, dark brown to black, coriaceous, ostiolate. Ostiole papillate, black, smooth, filled with hyaline cells, appearing as a white ring around ostiole. Peridium comprising 6–8 layers, outer layer heavily pigmented, comprising blackish to dark brown, thick-walled cells of textura angularis, inner layer composed of brown, thin-walled cells of textura angularis. Hamathecium comprising numerous, filamentous, branched, septate, pseudoparaphyses. Asci 8-spored, bitunicate, fissitunicate, cylindrical, pedicel furcate, rounded and thick-walled at the apex, with an ocular chamber. Ascospores mostly uniseriate, at first hyaline, becoming yellowish brown at maturity, ellipsoidal, muriform with 6–8 transverse septa and 3–7 vertical septa, strongly constricted at the central septa, weakly constricted at the other septa, with conical and narrowly rounded ends, lacking a mucilaginous sheath. Asexual morph: Unknown.
