 Scientific Name: Pseudocercospora diospyri-morrisianae

Pseudocercospora diospyri-morrisianae (Sawada ex)Goh & Hsieh, Trans. mycol. Soc. R.O.C. 2: 90. 1987.

 Description: Leaf spots indistinct on upper surface, but appearing as pale fuligineous angular patches at the lower surface, 3-7 mm wide. Fruiting hypophyllous, sparingly effuse. Stromata absent. Conidiophores loosely fasciculate at the stomatal openings or arise singly as side branches from the external procumbent hyphae, olivaceous, simple or branched, rarely geniculate, 0-2 septate, conically truncate at the apex, 5-49 × 2.5-4.5 μrn, conidial scars indistinct. Conidia subhyaline, subcylindrical or narrowly obclavate, substraight or curved, 3-7 septate, subacute or subobtuse at the apex, obconically truncate at the base, 40-90 × 2-3 μm; hilum unthickened.

Taiwan, Yilan. 25 July, 1926, holotype in Herb. NTU-PPE, .

 Habitat: On leaves of Diospyros morrisiana Hance.

 Note: The absence of stromata, with the pale conidiophores which are chiefly unfasciculate separate this fungus from other Cercospora sensu lato on Diospyros spp. Cercospora flexu-osa Tracy & Earle (Bul. Torrey Bot. Club 22:178, 1895) differs from this fungus by its darkly coloured conidiophores and conidia. Pseudocercospora diospyricola Goh & Hsieh (1987b) differs from this fungus by the simultaneous presence of densely fasciculate conidiophores on stromata and the extensive external secondary mycelium.
