Decalepis hamiltonii Wight & Arn is an endemic and endangered medicinal plant with monotypic, glabrous, climbing shrub belonging to the family Periplocaceae (Kostel.) Schltr (earlier under Asclepiadaceae). It is largely used in Ayurvedic system of medicine for curing the diseases like stomach disorders, gastric ulcers and for stimulating appetite. Leaf spot symptoms were observed on the leaves of Nannari plants in different areas of A.P. The symptoms initially appeared as minute, brown to deep brown, circular to oblong shape, as the disease progressed, these spots enlarged and changed to dark brown boarder with whitish or light brown centre and resulted in necrotic region. The fungus was cultured on potato dextrose agar medium and identified as Colletotrichum gloeosporioides based on cultural, morphological characteristics. To the best of our knowledge this is the first report of C. gloeosporioides on leaves of Nannari.
