Saprobic on dead branch in shaoguan city. Sexual morph: Undetermined. Asexual morph: Conidiostromata 350–460 μm long, 490–760 μm wide (x = 380 × 600 μm, n=10), gregarious, fissural, coriaceous, multilocular, black. Conidiomata 210–275 μm high, 150–205 μm diam (x = 235 × 180 μm, n=10), loculate; locules arranged by clustered, gregarious, with 3–7 locules forming groups immersed in conidiostroma, globose to subglobose. Peridium multi-layered, inner layer 25–45 μm wide, composed of dark-brown, thin-walled cells of textura angularis, with outer wall of lighter brown with textura angularis. Conidiophores with conidiogenous cells 25–40 × 2−3 μm, long, cylindrical, branched, hyaline to pale brown, thin-walled, microtubule in the top, spores are released from it one by one.
