China's matsutakematsutake a **** there are four major producing areas Yunnan Shangri-La , Sichuan Ganzi Prefecture Yajiang, Sichuan Ganzi Prefecture, Damba County, Stana, Sichuan Aba Prefecture Shaojin,. The four major mushroom-producing areas produce the majority of the country's matsutake mushroom production.
Matsutake is endemic to the Asian region, mainly distributed in Japan, the Korean Peninsula and China's Sichuan Ganzi, Aba Autonomous Prefecture, Tibet Linzhi City, Shangri-La, Chuxiong, Yanbian, Taiwan and other regions, it is known that there are varieties of matsutake mushrooms in the United States and Europe, but with less production and poor quality.

Grows on the forest floor of the mixed pine and oak forest belt in the temperate and cold temperate zone at an altitude of l600-2600 meters. With the pine genus, the oak genus of fibrous roots occur **** biological relationship, mycorrhizal site to form a diameter of 2-10 meters of the mushroom circle.
Matsutake mushroom mushroom circle size depends mainly on the nutritional conditions in the soil matsutake mushroom producing areas of the soil is mainly barren, acidic brown forest soil or mountain black loam, yellow loam. At the same time, the forest land is required to be sparse in dead branches and leaves. The age of forests for matsutake mushroom production is generally not less than 20 years. In 30-40 years old forest land is the peak period of matsutake mushroom production, and the production of forest land above 60 years old begins to decline.
