Abstract: Study on wood-inhabiting fungi is one of the active fields of mycology during past 30 years in China,and the study mostly focused on natural forest without fire disturbing.Forest fire changes forest ecology dramatically,and the fungi on charred wood are different from those in nature forests without fires.In this paper,we focused on the wood-inhabiting fungi growing on charred wood in Daxinganling forest areas.Seventeen species were reported:Antrodia sp.,Antrodia xantha,Ceriporiopsis mucida,Diplomitoporus lindbladii,Gloeophyllum carbonarium,Gloeophyllum sepiarium,Gloeoporus taxicola,Laurilia sulcata,Oligoporus sericeomollis,Phellinus igniarius,Postia caesia,Postia leucomallella,Postia tephroleuca,Schizopora flavipora,Skeletocutis ochroalba,Skeletocutis vulgaris,and Trichaptum fuscoviolaceum.Among them,eight species caused brown rot,and nine species caused white rot.Based on our field studies,eight species were pioneer fungi in charred wood,four species were common one,and three species were rare or threatened in the studied area.Setting up nature reserve should be the best way to protect the rare or threatened species of wood-inhabiting fungi.
