Leaf spot of Miscanthus sinensis Anderss. var. condensatus (Hack.) Makino occurred in Aogashimaisland and Hachijo-island of Tokyo Metropolis in 1999. The pathogen isolated from the diseased plant was identified as a species of Stagonospora. An inoculation test confirmed that this fungus was the causal agent of the disease. This is the first report of this disease in Japan.
