　Description： Leaf spots irregular, without distinct border, scattered, fuligineous to dark brown on the upper surface but reddish brown on the lower, 0.5-5 mm wide. Fruiting hypophyllous. Stromata absent. Secondary mycelium external, arising from a few hyphae which penetrate the stomata: hyphae almost colourless at the base where they are 1.5-3 μm wide, becoming pale brown (never very deep in colour) and wider (up to 5 um ) below the conidiophores, sparingly branched, smooth, sometimes tangled and forming loose ropes. Conidiophores borne terminally on and as lateral branches or as mere short projections of the secondary mycelial hyphae, bearing thickened conidial scars, simple, continuous or (when longer) 1-2 septate, 3-25 × 2-7 μm. Conidia varying from almost colourless to moderately pale olivaceous brown, subcylindric to ellipsoid, straight, catenulate (sometimes in branched chains), mostly 1-2 septate, rarely 3-septate, slightly constricted at the septa, 10-45 × 4-6 μm, hilum thickened.

　Note： Cercospora broussonetiae Chupp & Linder (Mycologia 29: 27, 1937) differs from this fungus by the presence of well developed stromata which give rise to dense fascicle of conidiophores and most importantly by its unthickened conidial scars.
