Biological Characteristics and Endangerment Mechanisms of Hypsizygus marmoreus
An experiment was conducted to study the biological characteristics of wild Hypsizygus marmoreus in Changbai Mountain using cottonseed hull as the cultivation material. Result indicates that H. marmoreus can use polysaccharide and organic nitrogen more efficiently. The optimal conditions for mycelia growth were obtained as the water content of cultivation material 60 percent, culture temperature 25 degrees C and pH 5. Although H. marmoreus is easy to form fruitbody, the development of fruitbody and the mass release of spores depend on special environmental conditions and the selection of substrates is restricted, which may be the immanent causes for species endangerment. Moreover, the sharply reduced area of virgin forests may be the external cause. Habitat protection of H. marmoreus should be enhanced with a view to conserving the wild population of this mushroom.
