Author: | Pseudocercospora diospyri-erianthae [Sawada ex] Goh & Hsieh, Trans. mycol. Soc. R.O.C. 2: 90. 1987. |

Description: | Leaf spots suborbicular, reddish brown, with a black margin, 1.5 - 6 mm wide. Fruiting chiefly hypophyllous. Secondary mycelium absent. Stromata well developed, globular, dark brown, 40-84 μm wide. Conidiophores densely fasciculate, divergent, subhyaline to pale olivaceous, cylindric, uniform in colour and width, straight to curved or undulate, rarely septate or geniculate, sometimes branched, truncate or rounded at the apex, 10-25 × 2-4 μm, conidial scars unthickened and inconspicuous. Conidia obclavate to cylindro-obclavate, straight to mildly curved, subhyaline to yellowish olivaceous, 3-9 septate, subacute at the apex, subtruncate or obconically truncate at the base, 35-90 × 2.5-3.5 μm; hilum incon-spicuous. | |||

Note: | A part of the Sawada's cotype is deposited in the U.S.DA. Mycological Herbarium. Pseudocercospora diospyri-morrisianae [Sawada ex] Goh & Hsieh (1987b) differs from this fungus by its unfasciculate conidiophores. Cercospora flexuosa Tracy & Earle (Bul. Torrey Bot. Club 22:178, 1895) is different from this fungus by its darkly coloured co-nidiophores and conidia. The presence of 1-3 septate conidia which are sharply obconic at the bases of Cercospora fuliginosa Ellis & Kellerman (Jour. Mycol. 3:103, 1887) separate it from this fungus. This species is different from Cercospora kaki Ell. & Ev. because of its well developed stromata and unbranched, densely fasciculate conidiophores. Pseudocercospora diospyricola Goh & Hsieh (1987b) differs from this fungus by the simultaneous presence of densely fasciculate conidiophores on stromata and extensive external secondary mycelium. | |||
