Abstract: The research progress of the roles of casing soil for the cultivation of edible fungi is reviewed. The species of edible fungi depending on casing soil, the bacterial structure compositions and dynamics in different development stages, biological functions and the molecular mechanism of interactions between them were focused. On the base of the reported achievement, the research prospects of casing soil microorganisms, challenges and solutions are summarized. It provides reference for development promoters and biological control agents to promote the development of edible fungi industry.

Key words: covering soil, edible fungi, bacterial structure, functional group, biological control
