A checklist of wood-decaying fungi in Guangxi Autonomous Region, South China

This study compiled the species diversity of wood-decaying fungi in Guangxi by integrating datasets from four institutes, particularly the identification on more than 6 000 specimens collected during 2023 and 2025. The results show that a total of 956 species is recorded, representing 2 phyla, 5 classes, 21 orders, 97 families, and 337 genera, and the phylum Basidiomycota (Agaricomycetes) dominates the assemblage.

Among these, Polyporales, Hymenochaetales, Agaricales, and Russulales are dominant classes, accounting for 85.25% of the total known species. A total of 11 dominant families and 12 dominant genera are recognized, representing 55.96% and 20.61% of the total known species, respectively. In addition, 70 species (7.32% of the total known species) were described with samples from Guangxi as their holotypes or paratypes.
