Re-Examination of Several ElsinoëSpecies Reported from Japan

AbstractElsinoëare plant pathogenic fungi that cause scabs, spotted anthracnose, and some morphological distortions on various plants, including woody plants, economically important crops, and ornamental plants. Taxonomical reexamination of Elsinoëspecies in Japan has not yet been conducted based on the modern species criteria. In this study, several Japanese isolates were reexamine based on the morphological and molecular-phylogenetic analysis of the internal transcribed spacer region (ITS), large subunit gene (LSU)m and protein-coding gene such as RNA polymerase II subunit (rpb2)and Translation elongation factor 1-alpha (tef).Japanese isolates were divided into four clades and three new species, Elsinoë hydrangeae, E. sumire,and E. tanashiensiswere proposed. One species, Sphaceloma akebiae,was transferred to the genus Elsinoë.
