Description:Teleomorph unknown. Lesions on living leaves starting as broadly spread punctiform depressions on leaf blades and leaf veins, becoming sub-circular yellowish brown and grayish centrally, up to 1 mm diam, surrounded by a halo of dark green tissue with a somewhat soaked appearance followed by a faint yellow outer circular area; on leaf veins the lesions are elliptical to elongated pale brown to purple; at later stages lesions coalesce and become flecked, sub-circular up to 15 mm diam leading to a blight of leaf apices, leaf margins or centrally and leading to girdling of the leaflets or whole leaves and to general blight and premature death of plants. External mycelium indistinct; Internal mycelium branched, septate, pale brown to grayish brown, 1.5–2.0 µm diam; Conidiophores hypophylous, isolate or in groups of up to three, straight to slightly sinuous, 147.5–320 × 10–12.5 µm, simple to occasionally branched, 3- 6 septate, chestnut brown at base becoming yellowish brown at apex, smooth; Conidiogenous cells tretic, terminal to intercalary, integrated simpodial, cylindrical, 25–165 × 10–15 µm; pale brown to yellowish; Conidiogenous loci conspicuos, 1–3 per cell, protuberant, up to 5 µm diam, thickened and darkened; Conidia dry, isolate, cylindrical to subcylindrical, 50–97.5 × 12.5–20 µm, apex and base rounded, 2–9 transversally septate (no longitudinal or oblique septae), often deeply constricted at septae and larviform (in freshly collected samples), hillum thickened and darkened, eguttulate, subhyaline to grayish, smooth, germinating both through apical and basal cells, occasionally also medianly. Germ tubes oriented perpendicularly to the main axis of the conidium.
