Pseudocercospora annonicola Goh & Hsieh, Cercospora and similar fungi from Taiwan. Maw Chang Book Company, Taiwan, Taipei: 22. 1990.

 Description: Leaf spots suborbicular to irregular, 1-8 mm wide, dark brown to almost black, identical on both surfaces. Fruiting chiefly hypophyllous. External mycelium present, hypophyllous, not abundant: hyphae repent, bearing short secondary conidiophores as side branches. Stromata subglobose to irregular, 20-40 μm wide, dark brown. Conidiophores densely fasciculate, subhyaline to pale olivaceous, straight to slightly flexuous, not branched, 0-1 septate, not geniculate, conically rounded at the apex, 5-20 × 2-3.5 μm, conidial scars unthickened or inconspicuous. Conidia subhyaline to very pale olivaceous, narrowly obclavate, sometimes almost linear, straight to mildly curved, 3-7 septate, acute or rarely subacute at the apex, short obeonic at the base, 20- 75 × 2.5-3 μm; hilum unthickened.

 Note: This fungus is very similar to Cercospora caracasensis Chupp & Muller (Bol. Soc. Vensz. Cien. Nat. 8(52):39, 1942) except for its angular leaf spots and epiphyllous fruiting, There are several other species of Cercospora described on Annona spp. and the differences are compared below: C. annonae Muller & Chupp (Arquiv. Inst. Biol. Veg. Rio de Janeiro 1:214, 1935) on Annona squamosa L. differs from this fungus by its cylindric, relatively longer (50-150 urn) and wider (5-6 μm) conidia.C. oblecta Sydow (Ann. Mycol. 33:236, 1935) on Annona senegalensis Pers. differs from this fungus by its relatively darker and wider (4-4.5 μm) conidia. C. scitula Sydow (Ann. Mycol. 33:236, 1935) on Annona senegalensis Pers. Differs from this fungus by its hypophyllous dark effuse fruiting, brown, wider conidiophores (4-6 μm) and brown, wider conidia (5-8 μm).
