Abstract

During a survey of ascomycetes in Yunnan Province, China, two new wood-inhabiting fungi were collected and identified. These novel species are described based on morphological characteristics and phylogenetic analyses of the ITS, LSU, rpb2 , and tef1 loci. The newly identified species are designated as Amphisphaeria zhaotongensis and Pallidoperidium yunnanense , belonging to the families Amphisphaeriaceae and Pallidoperidiaceae, respectively. These species are confirmed as distinct from their close relatives through phylogenetic analyses and morpho-anatomical comparison. The study provides detailed morphological descriptions, illustrative representations, and a phylogenetic tree, all of which contribute to the taxonomic positioning of these novel species.
