The Black-Staining Polypore is a fascinating mushroom that grows in large clusters on the ground or on wood. Its unique, dark appearance can change color when touched, making it an exciting find for young explorers!
Habitat: It lives in forests, often found near decaying wood or on the ground.
The Black-Staining Polypore has large, fan-shaped caps, often tan to reddish-brown, that merge into a massive, multi-lobed cluster at the base of trees. Its creamy white underside, made of tiny pores, quickly turns dark gray to black when bruised or cut. This distinct staining makes it easy to identify.
