Foliicolous to lignicolous. Thallus endophloeodal when lignicolous; crustose, irregularly netlike, dull fuliginous when foliicolous (Nag Raj 1981). Sexual morph: see Nag Raj (1981). Asexual morph: Conidiomata dull brownish black to glistening black, pycnidial, scattered to gregarious, immersed, oval to suborbicular in outline, subglobose to scutate in section view, unilocular, glabrous, clypeate, ostiolate. Ostiole single, centrally located, with an outer clypeus covering the hymenium. Conidiomatal wall composed of leathery, thick-walled, dark brown to black cells of textura epidermoidea in outer clypeus, gradually merging with membranous, gelatinous, thin-walled, hyaline cells of textura angularis in inner layer. Conidiophores reduced to conidiogenous cells. Conidiogenous cells arising from inner wall layer of conidiomata, hyaline, ampulliform to conical, with a broad inflated venter and a narrow attenuated neck, smooth-walled, with several percurrent proliferations, invested in mucus. Microconidiogenous cells hyaline, lageniform to cylindrical, smooth-walled. Conidia hyaline, subcylindrical to ellipsoidal, rounded at the both ends, 1-septate, not constricted at the septum, smooth-walled, guttulate, bearing unbranched, attenuated, mucoid appendage at each end. Microconidia hyaline, ellipsoid, unicellular, smooth-walled (adapted from Morgan-Jones 1974, Nag Raj 1981, 1993).
