Tuberous Polypore
A stalked, scaly, yellow-brown polypore that grows from buried wood or from a large underground sclerotium that can resemble buried wood or a potato. It occurs in Europe, Asia and North America. Fruit bodies have been grown from a wild Tibetan strain on supplemented sawdust in China.
Edible when young and well cooked; it becomes hard and leathery with age, and the sclerotium is not eaten as a vegetable. Dryad's saddle (Cerioporus squamosus) can look similar but has larger scales and a black stem base. The sources reviewed name no dangerous look-alikes.

Never eat a wild mushroom based on a web page — confirm with an expert.
Mycology is an evolving science: names, classifications and safety information change as research advances. Entries are compiled from cited sources and reviewed, but may be incomplete or out of date — check the sources, and never rely on this library alone to identify or eat a mushroom.
