Abstract: Auricularia polytricha (Mont.) Sacc. var. argentea Zhao et Wang is a new variety of the species Auricularia polytricha.lt was discovered by Zhao Dazhen in 1987. The sporophore is pure white. It has desirable characters, namely, its beautiful appearance, big and thick fruit bodies, tolerance to high temperature, resistance to trichoderma contaminations, high biological efficiency, nutritious, and good taste. It has been well proved that it is a kind of edible fungi being of important value to develop. Through five years and three generations acclimatizing cultivation and research, its biological characteristics and condition for growth were found out, three essential factors forming good structure of its body-substrate density, uniformity and its surface smoothness-were advanced, and a complete set of culture technics-making "U" holes on the wall of the culture polybag, sealing the polybag top and then capping it with a piece of plastic film,and hanging the bag in ditch -was worked out. These technics provided a scientific basis for developing and utilizing the edible fungus.
