Pseudocercospora jasminicola [M?ller & Chupp ex] Deighton. Mycol. Pap. 140:74 1976.

 Description: Leaf spots variable, typically deep brown, more or less irregularly suborbicular, up to 5 mm wide, surrounded by a narrow darker margin (on Jasminum subtriplinerve), sometimes starting as an irregular pale yellowish area with a reddish brown center which is irregularly swollen and rugose, especially on the lower surface, and later become brown (on J. sambac). Fruiting amphigenous, sometimes only hypophyllous, often scarcely visible but sometimes clearly visible as minute dark pustules densely and evenly distributed over the spot. Stromata variable, rarely absent, usually up to 30 um wide and 8 μm high below the conidiophore bases, filling thesubstomatal cavity, more rarely up to 50 μm wide. Conidiophores usually numerous or very numerous in a dense fascicle, sometimes only a few per fascicle and sometimes even emerging singly through a stoma with no stroma. On J. sambac, there are secondary conidiophores that arise singly from the procumbent external hyphae. The conidiophores are pale olivaceous, straight or slightly sinuous, sometimes slightly geniculate, thin-walled, smooth, simple, 0-2 septate, subtruncate at the apex, 5-30 × 2-4 /im; conidial scars unthickened. Conidia pale olivaceous, subcylindric to slightly obclavate, straight or slightly curved, smooth, thin-walled, obtuse at the apex, shortly tapered at the base to the 18-60 × 1.5-2.4 μm.
