Polypores are often found on rotting logs, and are rot-resistant to the extent that they themselves often last long enough to have moss growing on them.
Due to their texture, edible polypores are rare. However, some have been used in ritual and for utilitarian purposes for ages; the famous Ice Man was found carrying two different polypore species. One was notable for its antibacterial properties. The other was likely used for starting fires.
Many polypores are bracket fungi.
