Yunnan is very rich in wild mushroom resources.About 600species of wild edible mushrooms occur in the province.Among them nearly60species can be exploited presently on commercial scale.Noteworthy,various species of wild edible mushrooms occur in southern,central and northern parts of the province,thus people in different regions can use different resources.These wild edible mushrooms serve as one of the important natural resources on which people of all nationalities there rely,and play a certain role in improving the food structure and economic development.In order to rationally utilize and effectively conserve Yunnan's wild mushroom resources,it is necessary to develop mushroom deep-process industry,and to make fine products with high quality and value.Artificial improvement of ectomycorrhizal mushroom fruiting,introducing good strains as well as selecting new strains by using local wild mushrooms are important measures for sustainable development.Poisonous mushrooms especially the lethal ones,such as Amanita fuliginea and A.oberwinklerana,have relative great potential usage due to their poisonous chemical constituents,which should be studied further.
