Polyporus tuberaster, commonly known as the tuberous polypore^[1]^[2] or stone fungus,^[3] is a species of fungus in the genus Polyporus.^[4] It is easily identified by the fact that it grows from a large sclerotium that can resemble buried wood or a potato.^[5]

The yellow-brown cap is 4–15 cm wide, and ranges from convex to flat and even funnel-shaped.^[6] The whitish stalks can grow upwards of 10 cm high and 2–4 cm wide.^[6] The spores are white.^[6]

The species is edible but also tough.^[6]
