The members of Phyllachora are biotrophic, obligate plant parasitic fungi with a high degree of host specificity and species richness. This study discovered four new species in Shanxi and Shaanxi Provinces, China, and analyzed their morphology, genetics, and host relationships.
The members of Phyllachora are biotrophic, obligate plant parasitic fungi featuring a high degree of host specificity. This genus also features a high degree of species richness and worldwide distribution. In this study, four species occurring on leaf and stem of two different species of grass were collected from Shanxi and Shaanxi Provinces, China. Based on morphological analysis, multigene (combined data set of LSU, SSU, and ITS) phylogenetic analyses (maximum likelihood and Bayesian analysis), and host relationship, we introduce herein four new taxa of Phyllachora. Ancestral area reconstruction analysis showed that the ancestral area of Phyllachora occurred in Latin America about 194 Mya. Novel taxa are compared with the related Phyllachora species. Detailed descriptions, illustrations, and notes are provided for each species.
