abstract = {New diseases of Easter lily and lettuce were noticed in Japan and the pathogens were identified initially as Phytophthora megasperma and Phytophthora sp., respectively, based on morphological characteristics. We re-examined these isolates using phylogenetical and morphological analysis. In a detailed phylogenetic analysis of all clade members that was based on the sequences of eight genomic regions (rDNA large subunit [LSU], translation elongation factor 1 alpha [EF1-α], β-tubulin, 60S ribosomal protein L10 [60SL10], heat shock protein 90 [HSP90], triosephosphate isomerase/ glyceraldehyde-3-phosphate dehydrogenase [tigA], cox1), Easter lily isolates formed a monophyletic group with high bootstrap support. The unique colony pattern supported this result. In separate analyses of Phytophthora clade 8 based on rDNA ITS and the cox1 gene, the lettuce isolates grouped with P. lactucae (described from lettuce in Greece) in the rDNA ITS tree but formed a distinct group in the cox1 tree. The sporangia of Japanese lettuce isolates germinated directly, an uncommon feature in clade 8b. These results suggested that the Easter lily and lettuce isolates are novel species that we formally describe as Phytophthora lilii sp. nov. and P. pseudolactucae sp. nov., respectively. Moreover, P. lilii appears to represent a new Phytophthora clade.
