Grifola frondosa


Common Names: Hen-of-the-woods, maitake, ram's head, sheep's head, signorina mushroom
Category: Fungi
Sub-category: Polypores


A polypore mushroom that grows in clusters at the base of trees, particularly oaks. The fruiting body, occurring as large as 100 cm, is a cluster consisting of multiple grayish-brown caps which are often curled or spoon-shaped, with wavy margins and 2 to 7 cm broad. The under-surface of each cap bears approximately one to three pores per millimeter, with the tubes rarely deeper than 3 mm. The milky-white stipe (stalk) has a branchy structure and becomes tough as the mushroom matures. G. frondosa should not be confused with Laetiporus sulphureus, another edible bracket fungus that is commonly called chicken of the woods

It is typically found in late summer to early autumn.

Edible Notes: It is a commonly cultivated edible mushroom in Japan and can be often found in Connecticut supermarkets. It is edible and considered choice. Wild specimens should be checked carefully for insects as they are common throughout.
Warnings: Not known to be dangerous.
