Grifola frondosa is a polypore mushroom that grows in clusters at the base of trees, particularly oaks. The mushroom is commonly known among English speakers as hen of the woods, hen-of-the-woods, ram's head and sheep's head. It is typically found in late summer to early autumn. Like the sulphur shelf mushroom, Hen Of The Woods (Maitake) is a perennial fungus that often grows in the same place for a number of years in succession. It occurs most prolifically in the northeastern regions of the United States, but has been found as far west as Idaho.
