Guizhou Province, located in the eastern Yunnan-Guizhou Plateau, has complex topography and a warm, humid climate, providing high potential for fungal diversity. However, lignicolous macro-basidiomycetes in this region lacked systematic assessment for a long time. A comprehensive compilation of lignicolous macro-basidiomycetes in Guizhou was conducted based on specimen records of four investigation teams and recently published literature. A total of 738 species were recorded, belonging to 3 classes, 16 orders, 74 families, and 253 genera within Basidiomycota. The dominant class is Agaricomycetes, with the sum of species accounting for 97.15% of all known lignicolous macro-basidiomycetes species in Guizhou. The dominant orders are Polyporales, Agaricales, and Hymenochaetales, and the sum of species accounts for 81.44% (601 species) of all lignicolous macro-basidiomycetes in Guizhou. The ten dominant families include 391 species, accounting for 52.98% of total known species. The eleven dominant genera consist of 202 species, accounting for 27.37% of the total known species. Additionally, 48 species are described on the basis of holotype or paratype collected from Guizhou. This is the first province-level systematic overview of lignicolous macro-basidiomycetes in Guizhou Province.
