Popis: During a survey of fungi on Wurfbainia villosa in Guangdong Province, China, three novel species, Periconia endophytica, P. yangjiangensis, and P. wurfbainiae, belonging to Periconiaceae in Pleosporales, Dothideomycetes are proposed based on morphological and phylogenetic evidence. Periconia endophytica was isolated from the healthy leaves of W. villosa, while P. yangjiangensis and P. wurfbainiae were obtained from the dead stems of the same host. Notably, holomorphs were observed in P. wurfbainiae. The morphological characteristics of the novel taxa are compared with closely related species within Periconia. Illustrations, morphological descriptions, and phylogenetic analyses are provided for the novel taxa. Multilocus phylogeny of the combined internal transcribed spacer (ITS), large subunit nuclear rDNA (LSU), small subunit nuclear ribosomal rDNA (SSU), and partial translation elongation factor 1–α (tef1-α) regions supported the establishment of three new species. Furthermore, the taxa clustering in Periconia, Flavomyces fulophazii, and Sporidesmium tengii, are discussed for further investigation of their taxonomic placements.
