Grifola frondosa: The Hen of the Woods [ Basidiomycetes > Polyporales > Meripilaceae > Grifola . . . ] by Michael Kuo The "Hen of the Woods" is easily recognized by its smoky brown, wavy caps, organized in large clusters of rosettes arising from a single, branched stem structure. It is usually found near the bases of hardwood stumps, and occasionally on living hardwoods. Description: Ecology: Parasitic on hardwoods and conifers; possibly saprobic on decaying wood; causing a white butt rot; fruiting in large clusters of rosettes near the bases of trees; often reappearing in the same place in subsequent years; summer and fall; widely distributed east of the Rocky Mountains, rare in the west. Fruiting Body: Cluster 15-60 cm broad or more; individual caps 2-10 cm, fan-shaped, gray-brown (often with concentric zones), with wavy margins; pore surface lavender gray when young, becoming dirty whitish to yellowish, running down the stem(s); stem branches smooth, white, tough, usually lateral. Flesh: Firm; white; tough. Taste: Mild; odor mild. Spore Print: White. Microscopic Features: Spores 5-7 x 3.5-5 µ; smooth; broadly elliptical. REFERENCES: (Fries, 1821) S. F. Gray, 1821.
