Pythium root-rot of Sandersonia aurantiaca Hook. occurred on the island of Hachijo, Tokyo, between 2000 and 2001. Two species of Pythium isolated from the diseased plants were identified as Pythium irregurale Buisman and P. splendens Braun. Inoculation tests showed that these fungi were the causal agents of the disease. This is the first report of the disease in Japan.
