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. Many sources report it has a bitter taste, but others have found it delicious and suspect that the bitter specimens may be similar related species.[1] The mushroom has a large, brownish cap with large brown scales and may reach 30 cm (12 in) in diameter.
