Berkeley's Polypore (Bondarzewia berkeleyi) is a large, shelf-like mushroom that typically grows at the base of oak trees or on their roots. It is a saprophytic or weakly parasitic fungus, contributing to wood decay. The mushroom is characterized by its large size, often reaching several feet in diameter, and its cream to tan color. The upper surface is rough and uneven, while the underside features closely packed pores instead of gills. The flesh is thick and tough, especially in older specimens.
