Phellinus arctostaphyli

Species of fungus

Phellinus arctostaphyli, also known as the manzanita conk or the manzanita hoof polypore, is a species of shelf fungus. Native to western North America, this saprotrophic fungus only colonizes the wood of Ceanothus, Adenostoma, and Arctostaphylos. P. arctostaphyli is closely to related to three other North American Phellinus species, including Phellinus tremulae and Phellinus tuberculosus. However, in part due to the "economic insignificance of its hosts," P. arctostaphyli is relatively poorly studied as an individual species.
