 Scientific Name: Pseudocercospora acaciae-confusae

Basionym: Cercospora acaciae-confusae Sawada, Taiwan Agric. Res. Inst. Rept. 35: 105, 1928.

Pseudocercospora acaciae-confusae (Sawada) Goh & Hsieh, R.O.C. 4(2):39-56, 1989.

 Description: Spots on pseudofolium suborbicular, usually somewhat vein-limited and irregularly angular, 0.5-2 mm wide, dark brown or when older grey in the center with dark margin, often confluent. Fruiting epipseudophyllous, very few on one spot, visible as turfs of conidia under dissecting microscope. Stromata slight, stomatal, composed of pale yellowish cells or in mass very pale brown. Conidiophores 10 or more in a fascicle, pale yellowish brown, cylindric, erect, 0-1 septate, not branched, truncate or rounded at the apex, short, 10-20 × 3.5-4 μm, conidial scars unthickened and inconspicuous. Conidia pale yellowish brown, cylindric, straight to mildly curved, subobtuse to rounded at the apex, truncate or short obconically truncate at the base, 40-70 × 3.5-4 μm, hilum unthickened and inconspicuous.

Taiwan, Chiayi Hsien, Meishan, neotype, NCHUPP-179a.

 Habitat: On pseudofolium of Acacia confusa Merr.

 Note: Since the conidiophores and conidia of this fungus are not hyaline, it is not suitable to be placed in the genus Pseudocercosporella. No fruiting was found on the original type specimen collected by Sawada (Herb. NTU-PPE, Taipei, collected in Hsinchu, Feb. 23, 1927). However, by comparing the morphology of this fungus with that of Sawada's specimen and his description and illustration of Cercospora acaciae-confusae, we concluded that they are the same fungi. Specimen NCHUPP-179a is selected as the neotype.
