We are investigating saprobic Ascomycota in Guizhou Province, China. Fungal specimens collected from dead wood were identified based on morphological characteristics and multi-gene phylogenetic analyses of ITS, SSU, LSU, β-tubulin, ef1-α, and rpb2 sequence data. Three novel species, Neoroussoella guizhouensis, Roussoella guizhouensis, and Xenodidymella guizhouensis, are introduced, along with one new geographical record, Xenoroussoella triseptata. This study contributes to our understanding of the diversity of Ascomycota in Guizhou Province and the classification in Roussoellaceae.
