Parasitic on bamboo. Ascostromata forming near ends of host branches, near petiole bases, superficial, pinkish, irregular, tuberculate, fleshy, slightly pink, cells of ascostromata comprising cells of textura intricata. Locules immersed, arranged in a peripheral layer, subspherical or ellipsoidal, ostiolate. Peridium of locules comprising a single layer of light brown-walled cells. Hamathecium comprising relatively narrow, numerous, cellular pseudoparaphyses. Asci containing 6 ascospores, bitunicate, fissitunicate, cylindrical, with a long pedicel and a distinct ocular chamber. Ascospores uniseriate, fusiform, symmetrical, hyaline to light brown, muriform. Asexual state forming in young ascostromata. Locules immersed in ascostroma, arranged in rows or irregularly in the inner layer, cylindrical, ampulliform, globose, subglobose or irregular, thick-walled cells textura. Conidiophores reduced to conidiogenous cells, arising all around the basal region of the locules. Conidiogenous cells holoblastic, unbranched, discrete, indeterminate, cylindrical, septate, hyaline, smooth. Conidia fusiform, muriform, asymmetrical, hyaline to light brown, with irregularly arranged transverse and longitudinal septa, acute at basal, apex obtuse, or obtuse at both ends, thick-walled, smooth-walled.
