Known as Reishi by the Japanese and Lingzhi by the Chinese, this mushroom is perhaps the most renowned of all the traditional therapeutic fungi. Reputed to have many health-supporting properties, this mushroom is generally broken up, powdered and steeped in simple teas. Its flavor is strong, distinctive, and pleasant to most people. Reishi is a flat, shelf-like mushroom, with a smooth, lacquered finish. Plug spawn of this species do the best on oak, sweet gum, plum, elm or maple trees. Fruiting temperature 50-70 °F.
