Abstract

Two new graminicolous species of Phyllachora associated with hosts of the subtribe Saccharinae (Poaceae) (Phyllachora erianthi-rufipili on Erianthus rufipilus and P. spodiopogonis-sagittifolii on Spodiopogon sagittifolius) are described and illustrated from Yunnan Province, Southwest China. Species delimitation was based on morphological characteristics, molecular phylogenetic analyses, and host association. A high degree of host specificity was observed among Phyllachora species associated with Saccharinae grasses. In addition to the two new species, Pogonatherum crinitum is reported as a new host for Phyllachora pogonatheri. Furthermore, a modified CTAB method optimized for total DNA extraction of graminicolous Phyllachora is presented.
