species were recognized, with a further 281 being referred to synonymy under Cencospora api s a compound species (Crous and Braun, 2003). In a check-list cum monographic work on cercosporoid fungi occurring in India, Kamal (2010) found only 261 forms of Cercospora out of 935 to be validly recognizable. Further, a total of 483 forms (including 480 species and 3 varieties) have been transferred elsewhere on reasonable grounds, out of which 182 forms have gone to C apii s I. (Kamal, 2010) Cercospora leaf spot disease of Capsicum has been found to be caused by Cercospora capsici (Heald and Wolf, 1911) Cercospora capsicigena (Bhartiya et al 2000) and Cerco spora physalidis (To Anun et al., 2011). There has also existed nomenclatural ambiguity for Cercospora species belonging to the Capsicum host. C capsici was treated as a synonym of C. physalidis by Braun and Melnik (1997). In India, Cercospora leaf spot disease of Capsicum caused by C. capsici has been reported to prevail in varying proportions, with disease in- tensity ranging from 49 to 68.92% (Sharma, 1998: Bhat et al 2008). The northeast region of India is richly diverse in
