“…In the present study, a total of 1,407 specimens belonging to 74 wood-decaying poroid and corticioid species were collected from Zixishan area, including 63 white rot species (85.14% of the total) and the remaining 11 brown-rot species (14.86% of the total). In contrast, the proportion of brown-rot fungi in Zixishan area is similar to that in Huangshan Mountains, which is 14.12% (Cui & Jia 2011), and it is higher than Wuliangshan area and Haikou Forestry compared to 5.26% and 6.12% (He et al 2021, He & Zhao 2022), but it is lower than Great Xingan Mountains compared to 26.19% (Cui & Yu 2011) In forest ecosystems, wood-inhabiting poroid and corticioid fungal function as wood decomposers release matter and energy to the ecological system (Cui et al 2006, Wei 2010, Gafforov et al 2020. Combined nLSU, SSU, 5.8s, rpb1, rpb2, and tef1 phylogenetic analyses in the subphyla Agaricomycotina, Pucciniomycotina and Ustilaginomycotina, showed that 1928 currently used genera names are distributed in 241 families, 68 orders, 18 classes and four subphyla.…”
