Leaf spots suborbicular, very variable: sometimes only 1-2 min wide or up to 5 mm wide, grayish brown in the centre with a purplish margin; sometimes up to 15 mm wide, reddish brown, with an irregular margin, surrounded by a narrow yellowish zone. Fruiting amphigenous, chiefly hypophyllous but sometimes also plentiful on the upper surface, consisting of discrete olivaceous coremioid conidiophore fascicles loosely distributed over the spot. Stroma dark brown, up to 35 µm wide and 15 µm high. Conidiophores up to 50 or more in an erect loose coremioid fascicle which is expanded towards the apex, not adherent to each other, not branched, substraight to sinuous, varying from pale to moderately deep olivaceous, septate, smooth, 30-100 x 2-7 µm; conidial scars unthickened, often situated at the end of conspicuous conoid denticles but sometimes situated on flat shoulders (the conidiophores then being somewhat geniculate), more rarely on very short and much less conspicuous denticles (the conidiophore then being more or less sinuous). Conidia varying form pale to rather deep olivaceous, thin walled when pale but somewhat stouter walled when darker, mostly obclavate and often rostrate (the rostrum sometimes paler in colour), sometimes fusiform, substraight or slightly curved, smooth or often wrinkled-rough, 3-17 transversely septate, sometimes with one or two additional longitudinal or oblique septa, usually not constricted but sometimes slightly constricted at a few of the septa, 24-99 x 4-8 µm, rarely up to 9 µm wide.
Habitat: On leaves of Vilis vinifera L. (Vitaceae).
Specimen examined: NCHUPP-81, Jan. 12, 1984, NCHU Campus, Taichung, leg. T. K. G oh.
