Fomitopsis quercina is a species of mushroom in the order Polyporales. Commonly known as the thick-walled maze polypore, maze-gill fungus, oak-loving maze polypore, or oak mazegill, the specific epithet refers to the oak genus Quercus, upon which it frequently grows, causing a brown rot. It is found in Eurasia, Northern Africa and Australasia. Though inedible, it can be used as a natural comb and has been the subject of chemical research.
