 Note: Cercospora gomphrenae Ray (Mycologia 36:172, 1944) differs from this fungus by its thickened conidial scars and hyaline acicular conidia. Cercospora gomphrenicola Speg. (Anal. Soc. Cient. Argentina 13:29, 1882) differs from this fungus by its effuse fruiting and by its cylindric, mostly 1-septate, relatively wider (5-8 μm) conidia. Cercospora pretoriensis Chupp & Doidge (Bothalia 4:890, 1948) differs from this fungus by its epiphyllous fruiting and by its large stromata (up to 65 μm wide) and by its densely fasciculate, darkly coloured, tortuous conidiophores.
