Folk customs call some fungi "mushrooms", Phellinus linteus and Phellinus linteus mushrooms refer to one thing, and some medicinal fungi such as Phellinus linteus parasitic on tree trunks are called "Ganoderma lucidum".

But "Phellinus igniarius" can be divided into many kinds according to different parasitic tree species, such as mulberry Phellinus igniarius, poplar Phellinus igniarius, pine Phellinus igniarius, birch Phellinus igniarius and so on. Although their shapes and functions are different, they are still collectively called "Phellinus igniarius".
