Abstract : A fungus isolated from infected mango leaves was identified as G. citricarpa by morphological and physiological characters of its perithecia and ascospores. This is the first report of this fungus on mango leaves. Inoculated leaves developed lesions 7-10 d after ascospore germination. Young lesions appeared as minute, sunken, blackish depressions on upper and lower leaf surfaces. Mature lesions were roughly circular, 1-2 mm diam. The fungus was consistently reisolated from these lesions. Benomyl gave good control of the disease.
