Saprobic, Asexual morph: Pycnidia: 90-180 x 90-210 µm, subglobose, ellipsoidal or pyriform, immersed, ostiolate, epapillate to papillate, coriaceous, thin-walled, brown to black, solitary or gregarious. Peridium: 8-12 µm thick, usually composed of two layers of elongate, lenticular, thick-walled cells, dark on the outside, light-coloured near the venter, forming a textura angularis. Papillae: 25-30 um high, 45-50 µm in diam., conical or cylindrical, centric or eccentric, projecting above the surface of the host. Ostioles: 20-30 µm in diam., ostiolar canal filled with mucilage and some small hyaline, periphysoid cells broken off the wall. Conidiogenous cells: phialidic, flask-shaped, hyaline, originating along the inner wall of the peridium. Conidia: 10-19 x 4-7 µm, blastic, cylindrical with rounded ends to ellipsoidal, one-septate in the middle, rarely with an additional septum in the lower or upper half, very seldom three-septate, not or slightly constricted at the septa, smooth, hyaline to yellowish or light brown, enclosed in an indistinct, irregular, mucilaginous sheath. Sexual morph: Undetermined.
