Horse Hooves

About plant names...

Horse hooves are native to the northern half of North America.

Identification: These large shelf-like fungi lives on trunks of birch and aspen, as well as alder, madrone, manzanita, maple, and willow, often on living trees. It forms dark brown or black, woody, hoof-shaped fruits 1¾-8" (5-20 cm) around and almost as thick. As it ages it becomes cracked or furrowed and darker in color. It generally has no stalk.

Edibility: Horse hooves are not edible, says David Arora, author of Mushrooms Demystified, “unless you are fond of wood.” Tom Volk’s Fungus of the Month site describes its possible use in conjunction with tobacco by native Americans; similar use is also attributed to some Inupiaq and Yup’ik Eskimos of Western Alaska in the past and even today. Ashes from the mushrooms are said to contribute “a powerful kick” when smoked with tobacco. Research indicates that this is a serious health risk.
