In 2007, a rust disease of ohia (Metrosideros polymorpha) was found in Japan. We identified this pathogen as Puccinia psidii based on its morphological characters and the internal transcribed spacer (ITS) sequence of the ribosomal DNA. This pathogen was pathogenic on Eucalyptus amplifolia and Eucalyptus rudis in addition to previously reported host species. This is the first report in Japan of a rust disease on ohia and the occurrence of its causal fungus, Puccinia psidii.
