Abstract

This study presents the identification of four novel Xylaria species, discovered in the karst region of China. The discovery was facilitated by a rigorous analysis that encompassed both morpho-anatomical features and multi-locus phylogenetics utilizing sequences from the ITS, rpb2, and TUB2 loci. The newly identified species are designated as Xylariajichuanii sp. nov., X.nanningensis sp. nov., X.orientalis sp. nov., and X.taiyangheensis sp. nov. The distinction of these species from their known counterparts was verified through comparison of morphological features and phylogenetic analysis. The study further provides detailed morphological descriptions, illustrative representations, and a phylogenetic tree, all of which contribute to the taxonomic positioning of these novel species.

Keywords: Folicolous fungi; Fungal systematics; Southwest China; Xylariaceae; taxonomy.
