Polyporus tuberaster, commonly known as the tuberous polypore[2][3] or stone fungus,[4] is a species of fungus in the genus Polyporus.[5] It is easily identified by the fact that it grows from a large sclerotium that can resemble buried wood or a potato.[4]
The yellow-brown cap is 4–15 centimetres (1+1⁄2–6 in) wide[4] 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 and spore print are white.[4][6]
The species is edible but also tough[6] unless young and well cooked.[4]
