 Saprobic on branches of Berberis buxifolia. Sexual state: Ascostromata 1000−1500 × 150−180 μm ( = 1100 × 150 μm, n = 20), black, superficial, semi-immersed to erumpent, solitary or scattered, subglobose to broadly ellipsoid, coriaceous, multiloculate, with 8−10 locules, cells of ascostromata dark brown to black cells of textura angularis, sometimes ostiolate. Peridium of locules 20−40 ( = 35 μm, n = 20) comprising lightly pigmented to light brown cells of textura angularis. Hamathecium lacking pseudoparaphyses. Asci 50−60 × 14−20 μm ( = 55 × 1 7 μm, n = 20) 8-spored, bitunicate, fissitunicate, clavate to broadly-clavate, with a short, broad pedicel, thickened and rounded at apex with an ocular chamber. Ascospores 15−20 × 6−10 μm ( = 16 × 8 μm, n = 40), uniseriate or discontinuously arranged, partially overlapping, reddish brown to dark yellowish brown, muriform with three transverse septa and 1−2 vertical septum in the central cells when mature, constricted at the septa, oblong, smooth to verruculose, without a sheath.
