Ostiole papillate, blackish-brown to black, smooth, comprising brown cells. Peridium with 2–3 layers, heavily pigmented, thin-walled, comprising brown to dark brown cells of textura angularis. Hamathecium comprising numerous, filamentous, branched, septate, pseudoparaphyses. Asci 8-spored, bitunicate, fissitunicate, cylindric-clavate to clavate, short pedicellate, thick-walled at the apex, with minute ocular chamber. Ascospores overlapping 1–2-seriate, ellipsoidal to sub-fusiform, muriform, upper part wider than the lower part, initially hyaline, becoming yellowish-brown at maturity, with 5–6-transverse septate and 1-longitudinal septum except at the end cells, constricted at the septa, conical and rounded at the ends, with smooth surface, with or without being surrounded by a thick mucilaginous sheath.
