Meripilus giganteus
The giant polypore
Description
Fruiting bodies are up to 30 cm across or more, composed of multiple caps sharing a branched, stemlike base. Caps are 5–20 cm across; fan-shaped; finely velvety or bald; whitish becoming brownish with age; often radially streaked and concentrically zoned; the margin thin, bruising and aging black. Pore surface is whitish, becoming dirty tan; bruising dark brown to black when fresh; with 6–8 round to angular pores per mm; tubes are up to 8 mm deep. It is parasitic on living oaks and other hardwoods causing a white rot. It grows in large clusters of rosettes near the bases of trees, often reappearing in the same place in subsequent years in summer and fall.
