Anthracnose of Cacalia delphiniifolia Siebold et Zucc. occurred on Toshima Island of Tokyo Metropolis in 2009. The causal fungi isolated from the diseased plants were identified as Colletotrichum dematium (Persoon:Fries) Grove and Colletotrichum gloeosporioides (Penzig) Penzig & Saccardo. Inoculation tests showed that these fungi were the causal agents of the disease. This is the first report of the disease in Japan.
