Abstract
During an investigation of Xylariaceae from 2019 to 2020, isolates representing eight Nemania (Xylariacese) species were collected from Yunnan, Guizhou and Hainan Provinces in China. Morphological and multi-gene phylogenetic analyses, based on combined ITS, α-actin, rpb2 and β-tubulin sequences, confirmed that six of them are new to science, viz. Nemania camelliae, N. changningensis, N. cyclobalanopsina, N. feicuiensis, N. lishuicola and N. rubi; one is a new record (N. caries) for China and one is a known species (N. diffusa). Morphological descriptions and illustrations of all species are detailed. In addition, the characteristics of Nemania are summarised and prevailing contradictions in generic concepts are discussed.
