Saprobic on dead twigs of Acer campestre L. Sexual morph: Ascomata scattered, immersed, globose to subglobose or irregular in shape, glabrous, brown to dark brown, ostiolate. Ostiole short papillate, black, smooth, filled with reddish cells. Peridium comprising 4–5 layers, outer layer pigmented, comprising brown to dark brown, thin-walled cells of textura angularis, inner layer composed of hyaline, loosen, cells of textura angularis. Hamathecium comprising numerous, filamentous, branched, septate, pseudoparaphyses. Asci 8-spored, bitunicate, cylindrical, short pedicellate, apically rounded with broad ocular chamber. Ascospores obliquely bi-seriate, ellipsoidal to subfusiform, initially hyaline to pale yellow, becoming pale brown at maturity, 3-trans-septate, with the primary septum almost median, constricted at septa, slightly curved, smooth-walled with guttules, ends remaining cone-shaped, with rounded ends.
