Maitake (Hen of the Woods) Agar Plate

Description

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, ram’s head and sheep’s head. It is typically found in late summer to early autumn outdoors.

Like the sulphur shelf mushroom, G. frondosa is a perennial fungus that often grows in the same place for several years in succession. It occurs most prolifically in the northeastern regions of the United States, but has been found as far west as Idaho.[citation needed]

Grifola frondosa grows from an underground tuber-like structure known as a sclerotium, about the size of a potato. The fruiting body, occurring as large as 100 centimetres (40 inches), rarely 150 cm (60 in), is a cluster consisting of multiple grayish-brown caps which are often curled or spoon-shaped, with wavy margins and 2–10 cm (1–4 in) broad. The undersurface of each cap bears about one to three pores per millimeter, with the tubes rarely deeper than 3 mm (1⁄8 in).The milky-white stipe (stalk) has a branchy structure and becomes tough as the mushroom matures.
