: Conidiomata pycnidial, scattered, immersed or semi-immersed, globose to ovoid, unilocular, 280550 µm diam. Disc black, 180330 µm in diam. Ostioles single, central, 65115 µm. Paraphyses present, hyaline, thin-walled, arising from the conidiogenous layer, extending above the level of developing conidia, tip rounded, aseptate, up to 74.5 × 2.5 µm. Conidiophores reduced to conidiogenous cells. Conidiogenous cells hyaline, smooth, thin-walled, holoblastic, cylindrical, phialidic, proliferating internally with visible periclinal thickening, 9.529.0 × 1.04.0 µm. Conidia initially hyaline, becoming brown with age, dark brown, thick-walled, oval, with obtuse or gradually acute apex, rounded, gradually acute base, aseptate, 24.036.5 × 15.020.5 µm (av. ± S.
