Lesions on the upper leaf surface, scattered to confluent, distinct, angular, spots elliptic to suborbicular, reddish-brown to dark brown, 2-5 mm, on the lower leaf surface similar. Colonies on PDA 10-15 mm diam. in 2 weeks, with an even, dark-brown margin. Surface fold, with gully shape. Conidiophores arising singly as lateral branches of superficial hyphae, semi-macronematous to macronematous, mononematous, erect to flexuous, sometimes curved, unbranched, thick-walled, non-smooth surface, 1-3-septate, cylindrical, geniculate, brown, 35-135 x 5-7 µm . Conidiogenous cells integrated, terminal, 5-10 µm long, sympodial, polyblastic, cylindrical, geniculate, scars slightly thickened and darkened, 0.5-1.5 µm in diam. Conidia solitary in simple or occasionally branched chains, short to long cylindrical, some ends swollen straight to somewhat curved, 8-41 x 2-5 µm , unseptate, light brown, thin-walled, verruculose, 2-3.5 µm wide.
