RÉSUMÉ

Grifola frondosa (Dicks.: Fr.) S. F. Gray, best known as maitake, is an important medicinal and a choice edible mushroom. As a white-rot fungus, causing butt rot, the mushroom is associated primarily with deciduous forests in Northern temperate regions in North America, Europe, and countries such as Japan and China. The mushroom can also be found at high elevations with temperate climate in subtropics. Characteristics of habitats (in terms of distribution, altitude, major host-substrate tree species, soil, and climatic factors including lighting, temperature, and relative humidity); ecological characterization of the mushroom; life history (morphogenesis in nature); and morphological studies of the fruiting body are described. Of special interest are recent reports of possible sclerotia-producing strains in G. frondosa in North America and China. A description of G. frondosa sclerotia is given. These rare strains could be important, as G. frondosa sclerotia can be valuable in medicinal use.
