Anamorph: conidiomata acervuli, 250-400 µm diam. ± roud or angular due to development between leaf veins, surrounded by a narrow to broad necrotic zone, dark brown, somewhat pulvinate. Conidiophores and setae formed on a cushion of medium brown, angular to roundish cells 5-9 μm diam. Setae medium to dark brown, smooth-walled, 35-75 μm long, 5-7 µm diam. at the ± conical base, 1–3-septate, tapering, apex obtuse to acute. Conidiophores hyaline to medium brown, smooth-walled, sometimes septate and branched, to 20 μm long. Conidiogenous cells (8-) 11-16 x 3-3.5 μm, hyaline to medium brown, smooth-walled, ampulliform to conical, collarette 0.5–1 μm long, periclinal thickening visible. Conidia (16-) 17.5-20.5 x 3.5-4.5 µm, hyaline, ± cylindrical but usually slightly curved, the apex obtuse and the base with a minute truncate scar, aseptate, hyaline, thin-walled, smooth, without an epispore, gelatinous sheath or appendages. Teleomorph: not known.
