Neem (Azadirachta indica A. Juss.) trees in India showing characteristic die-back symptoms consistently yielded a species of Phomopsis. Uecker(1988) describes the difficulties in identifying unknown species of Phomopsis. The name Phomopsis is a nomen conservandum (Riedl et al., 1981). Wechtl (1988, 1990) made detailed morphological and anatomical studies on genitype Phomopsis lactucae and several other species occurring on Compositae and Umbelliferae. Uecker (1988) published a world list of Phomopsis species on different host plant species. Comparison of the Phomopsis species isolated from A. indica with the earlier described species, Phomopsis abdita (Sacc.) Traverse on Melia azedarach L.(Uecker, 1988; Bilgrami et al., 1991; Ellis & Ellis, 1985) revealed that it was not described previously. This is the first report of a Phomopsis species on A. indica from India
