　Description： Leaf spots suborbicular to irregular, 1.5-6 mm wide, pale grayish brown at the center, with a narrow dark brown margin. Fruiting hypophyllous, invisible. Stromata absent. Secondary mycelium external: hyphae subhyaime to very pale olivaceous, 1-1.5 μm wide, repent, sep-tate, bearing conidiophores as erect branches. Conidiophores sometimes arising singly from a stoma, or rarely 2-3 in a fascicle but chiefly borne singly as lateral branches on the exter-nal secondary mycelial hyphae, subhyaline or very pale olivaceous, erect, straight below and serrated at the upper part towards the apex, 0-2 septate, constricted at the septa, not branched, mildly geniculate at the apex and saw-like or wavy in margin with small but unthickened conidial scars on the shoulders, 6-30 × 2-3 μm. Conidia subhyaline, narrowly obclavate to linear, straight to curved, 1-9 septate, sometimes constricted at the septa, acute to subacute at the apex, obconic or narrowly subtruncate at the base, 20-80 × 1.5-2 μm; hilum unthickened.

　Note： This fungus differs from others on Ehretia spp. (Cercospora ehretiae Togashi & Katsuki (Bot. Magazine, Tokyo 65:20, 1952) on E. thyrsifloria; Cercospora ehretiicola Saleem & Mirza (Pakistan F. Bot. 9(2):151, 1977) on E. acuminata sensu Hemsl. and Pseudocercospora ehretiae [Sawada ex] Goh & Hsieh (1989b) on E. dicksonii) by its chiefly unfasciculate, very pale conidiophores and by its subhyaline narrowly obclavate or filiform conidia.
