Pseudocercospora bakeriana Deighton, Mycol. Pap. 140: 39. 1976.

 Description: Leaf spots none. Fruiting hypophyllous, floccose, deep grayish olivaceous, vein-limited and irregular, up to 5 mm wide. Stromata none. A few pale olivaceous hyphae, arising from swollen substomatal hyphae, penetrate a stroma, becoming more swollen and closely septate near the point of emergence and give rise to a fascicle of 4-12 or more conidiophores and also hyphal threads which constitute the secondary mycelium. Secondary mycelium external: hyphae laxly repent or arcuate, olivaceous, septate, smooth, bearing conidiophores terminally and laterally. Conidiophores medium olivaceous, suberect or divergent in the fascicle, smooth, sinuous or slightly geniculate, simple or branched 1-3 times along the length, multiseptate, up to 130 μm long, 3-7 μm wide; conidial scars unthickened, 1.5-3 μm wide. Conidia medium olivaceous, cylindric to obclavato-cylindric, straight or slightly curved, 4-10 septate, smooth, 30-65 × 5-8 μm.

 Note: Saccardo published Cercospora bakeriana Sacc. in year 1914 on Caesalpioia pulcherrima Sw. However it is a true Cercospora which differs distinctly from this fungus by its thickened conidial scars and by its hyaline acicular conidia. Therefore, the name Cercospora bakeriana Sacc. published in 1919 is illegitimate.
