Sarcodon imbricatus, commonly known as the shingled hedgehog or scaly hedgehog, is a species of tooth fungus in the order Thelephorales. The mushroom is edible.
This mushroom has long been regarded as a precious mountain treasure in Chinese history, and it is one of the favorite tributes of the dynasties. There is no eating habit of this mushroom in Europe and America, and the main areas of consumption in Southwest China, Japan and Southeast Asia.
The mushrooms, or fruiting bodies, can be quite large in size. the brownish or greyish cap measures up to 30 cm (12 in) in diameter and is covered with coarse darker brown scales. It is funnel-shaped. The underside bears soft, pale grey 'teeth' rather than gills. These are 0.5–1 cm long and brittle. The pale grey or brown stipe may reach 8 centimetres (3.1 in) high and 3 centimetres (1.2 in) wide, and may be narrower at the base and is sometimes eccentric.
