Taxonomical re-examination of the genus in Japan.

is a genus of plant pathogenic fungi associated with various woody plants. Since has very similar morphological characteristics to the genus , molecular phylogenetic analysis is essential to determine its taxonomic position. In Japan, a comprehensive taxonomic study of the genus has not been conducted.

Taxonomical Study of Noteworthy Species of in Japan.

The reexamination of the fungal genus on 12 plant species of 10 families was carried out based on molecular phylogenetic analyses using the regions of translation elongation factor 1-α, β-tubulin, DNA-directed RNA polymerase II subunit, and internal transcribed spacer region of rDNA and morphological characteristics. Japanese isolates were divided into five clades and include , , , and spp. Two species, and have been newly added to the Japanese mycoflora, but their host plants are not specified.
