Morphological and phylogenetic analyses reveal two new species of Camporesiomyces (Tubeufiaceae, Tubeufiales) from terrestrial habitats in China

During a survey of saprobic fungi in karst landscapes of Guizhou Province, China, fresh specimens were collected from decaying wood in terrestrial habitats. Phylogenetic analyses of a combined dataset (ITS, LSU, <i>tef</i>1-α and <i>rpb</i>2) along with morphological characteristics support the introduction of two novel species, <i>Camporesiomyces qizhifengensis</i> and <i>C. yusheensis</i>. Detailed descriptions, illustrations and phylogenetic evidence are provided to substantiate their taxonomic placement. Additionally, a checklist of currently accepted <i>Camporesiomyces</i> species supported by molecular data is included. This is the first report of <i>Camporesiomyces</i> in Guizhou, adding to the regional biodiversity of karst habitats and highlighting the ecological importance of these unique environments. The findings underscore the need for continued exploration of fungal diversity in underexplored regions.
