Ganoderma is a genus of polypore mushrooms that grow on wood, and include about 80 species, many from tropical regions.[1] Because of their extensive use in traditional Asian medicines, and their potential in bioremediation, they are a very important genus economically. Ganoderma can be differentiated from other polypores because they have a double-walled basidiospore. They are popularly referred to as shelf mushrooms or bracket fungi.
