Cercospora bombacis Goh & Hsieh, Trans. mycol. Soc. R.O.C. 2:87-88. 1987.

 Description: Leaf spots scattered, suborbicular to irregular, 2-5 mm wide, often confluent, at first uniformly brown, finally dingy grey at the centre with an indefinite dark brown border. Fruiting amphigenous. Secondary mycelium absent. Stromata slight or up to 60 μm wide, subglobose, dark brown. Conidiophores fasciculate, meagre or may up to about 40 in a dense fascicle, pale brown, paler towards the apex, uniform in width, sometimes branched, geniculate, multiseptate, truncate at the apex, 50-180 × 4-6.5 μm; conidial scars conspicuously thickened. Conidia acicular, hyaline, straight or slightly curved, closely multiseptate, acute at the apex, truncate at the base with a thickened hilum, 50-120 × 3-4 μm.

 Note: Sawada proposed the name Cercospora bombacis for this fungus in his manuscript (No. 15). Katsuki (Descr. Catal. Taiwan Fungi Xl:222, 1959) regarded this fungus as Cer-cospora pachirae Chupp & Müller (Bol. Soc. Venez. Cien. Nat. 8(52) :52, 1942). However, it is concluded from the examination of Sawada's original specimen that the name Cerco-spora bombacis should pertain to this fungus since it is a true Cercospora which differs from C. pachirae Chupp & Müller by its plainly multiseptate, geniculate, darkly coloured conidiophores, and by its hyaline acicular conidia, and most importantly by the thickened conidial scars.
