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]
