 Scientific Name: Pseudocercospora diospyricola

Pseudocercospora diospyricola Goh & Hsieh, Cercospora and similar fungi from Taiwan. Maw Chang Book Company, Taipei, Taiwan: 106-107. 1990.

 Description: Leaf spots amphigenous, angular, vein limited, 1-2.5 mm wide, dark olivaceous brown. Fruiting amphigenous. Secondary mycelium external: hyphae arising from the base of the fasciculate conidiophores, particularly from the hypophyllous fascicle, bearing secondary conidiophores as side branches, very pale olivaceous to pale olivaceous brown, 1-3 μm wide. Stromata amphigenous, meagre to well developed, up to 45 μm wide (especially those on upper surface), rupture the stomata. Conidiophores loosely to densely fasciculate and also arising from the external secondary mycelial hyphae, very pale to medium olivaceous brown, 0-3 septate with slight constrictions, sometimes branched, somewhat clavate or irregular in width, curved or sinuous, 1-2 mildly geniculate, narrowly rounded or subtruncate at the apex, 5-35 × 3-5 μm; conidial scars inconspicuous and unthickened. Conidia very pale olivaceous, obclavate to subcylindric, straight to mildly curved, 1-8 septate, smooth, subacute to subobtuse at the apex, obconically truncate at the base with an unthickened hi-lum, 15-50 × 2-3 μm.

Taiwan, Changhua Hsien, 23 Oct. 1985, holotype, NCHUPP-185and isotype in IMI Herbarium No: 312074.

 Note: This fungus differs from others on Diospyros spp. by its amphigenous fruiting and the simultaneous presence of stromata and well developed external mycelium.
