| Note： |
There are several other species of Cercospora sensu lato on the host genus Erythrina namely C. erythrinae Ellis & Everhart (Jour. Mycol. 3:18, 1887), C. erythrinicola Tharp (1917), C. tomentosae Hansford (Proc. Linnean Soc. London 1942-43:59, 1943), Pseudocercospora pittieri (H. Sydow) Deighton (1976) and P. erythrinigeiia Yen (1978d), but this fungus is distinct from others by having relatively much narrower conidia which are variable in shapes and almost colourless in colour. | |||
