Wood-inhabiting fungi are abundant in China, but their distribution is uneven, with more fungi in southwest China and fewer fungi in northwest China. During the investigation of wood-inhabiting fungi in Xinjiang, we collected a large number of specimens. Eight specimens growing on

China is rich in wood-inhabiting fungal resources, and more than 2000 species of the woody fungi have been reported (
The Xinjiang Uygur Autonomous Region is located in northwestern China, and, as the largest province in China, it covers an area of 1,664,900 square kilometers. There is a typical temperate continental arid climate, with an extremely uneven distribution of water resources in time and space, more in the west and less in the east, more in the north and less in the south, more in the mountains and less in the plains (
During the investigation of wood rot fungi in Xinjiang, we collected a large number of specimens, including two belonging to
