Polyporus tuberaster
Polyporus tuberaster, commonly known as the tuberous polypore or stone fungus, is a species of fungus in the genus Polyporus. It is easily identified by the fact that it grows from a large sclerotium that can resemble buried wood or a potato.
The yellow-brown cap is 4–15 centimetres (1+1⁄2–6 in) wide and ranges from convex to flat and even funnel-shaped. The whitish stalks can grow upwards of 10 cm high and 2–4 cm wide. The spores and spore print are white.
