Reishi
Reishi is the common name of a group of closely related mushrooms(Ganoderma sp.) of the polypore type. Ganoderma lucidum is the best studied of the group and has over one thousand years use in China. Ganoderma applantum and oregenase are two other common types. Applantum is known as the Artist's conk due to it's rapidly brown bruising pores(pictures may be drawn with the fingernail and are preserved when it is dried).These three species are most likely the result of selective adaptation and are cross fertile.
