As shown on Wikipedia Site: ( https://en.wikipedia.org/wiki/Polypore )
“Polypores are a group of fungi that form fruiting bodies with pores or tubes on the underside (see Delimitation for exceptions). They are a morphological group of basidiomycetes like gilled mushrooms and hydnoid fungi, and not all polypores are closely related to each other. Polypores are also called bracket fungi, and their woody fruiting bodies are called conks. ”
