1. Different distribution areas: Russula is distributed in Hebei, Shanxi, Jilin, Heilongjiang, Liaoning, Yunnan, Tibet, Guangdong, Hunan and Sichuan in China. Tricholoma matsutake is distributed in parts of North China and Northeast China, mainly in the mountainous areas of northern Hebei and northwestern Liaoning.

2. Different nutritional values: Russula contains protein that people often need, and dietary fiber also contains a small amount of essential elements, such as potassium, sodium, zinc, manganese and copper. Tricholoma matsutake contains chromium, polyol, vitamin E and so on.

3. Different growing environments: Tricholoma matsutake is born in the overground weed jungle of pine forest, and forms ectomycorrhiza with pine trees, which is clustered, scattered or solitary. Tricholoma matsutake grows in shaded or semi-shaded pine forests at an altitude of 700 to 500 meters.

Extended data:

The biological characteristics of Tricholoma matsutake mycelium began to grow at 8℃, the optimum temperature was about 20-24℃, and it stopped growing at 32℃. The relative humidity of the air during mushroom production is about 85%. The soils are mainly forest brown soil, mountain red soil and mountain yellow soil. The pH value of soil is generally between 4.5 and 5.5. The humus layer is very thin, usually less than 3 cm.

Tricholoma matsutake mostly occurs in areas with a slope of 20-40, west, southwest or northwest, with high and dry terrain and good drainage. The age of mushroom-producing forest is generally not less than 50 years. Mushrooms began to grow in Yanbian area of China in mid-July, and entered the rich period in mid-August.
