Hericium is a genus of edible mushrooms in the Hericiaceae family. Species in this genus are white and fleshy and grow on dead or dying wood; fruiting bodies resemble a mass of fragile icicle-like spines that are suspended from either a branched supporting framework or from a tough, unbranched cushion of tissue. This distinctive structure has earned Hericium species a variety of common names—monkey's head, lion's mane, and bear's head are examples. Taxonomically, this genus was previously placed within the order Aphyllophorales, but recent molecular studies now place it in the Russulales.
