Boletus caps are 5 to 30 cm in diameter, hemispherical or oblate hemispherical, and gradually become flattened in the later stages.

Boletus is the collective name for fungi such as Boletaceae and Boletaceae. They are wild and edible mushrooms. Except for a few varieties that are toxic or bitter and cannot be eaten, Most varieties are edible. There are mainly white, yellow and black boletus. The cap is flat and hemispherical, smooth, non-sticky, light nude in color, and the fungus flesh is white with a sauce-like aroma and can be used as medicine. Thigh mushroom is rich in nutrients and has a delicious taste. It is one of the most delicious wild edible fungi. It can be exported to Europe, America, Japan and other countries, and is very popular among foreign businessmen.

This fungus has a large body, thick flesh, thick stalk, sweet and delicious taste, and rich nutrition. It is a world-famous edible fungus. White beef liver grows in coniferous and mixed forest areas such as Yunnan pine, alpine pine, oak (so it is also called oak), golden bark oak, and green oak. It grows singly or in groups. Often forms mycorrhizae with the roots of oak and pine trees. It is produced from June to October, slightly earlier in warm areas, and later in cool and alpine areas. It is also partially distributed in Kashgar area.

Growth conditions of boletus

1. Temperature

Temperature is an important indicator that affects the occurrence of delicious boletus. In turn, temperature is a factor composed of a variety of factors. Results determined by factors (slope, aspect, altitude). Temperature, in turn, affects humidity, which also has an effect on the occurrence of delicious porcini. Delicious boletus mycelium grows at 18℃~30℃, but the optimal temperature is 24℃~28℃; its fruiting body can grow and develop in the range of 5℃~28℃, and the suitable temperature for fruiting body formation is 16℃ ℃~24℃, below 12℃ it is not easy to form fruiting bodies.

2. Moisture and humidity

Delicious porcini mushrooms are mostly concentrated between 300m and 600m above sea level. They also grow at 200m or 700m, but in small numbers. Since altitude is an indicator factor of mountainous climate, that is, temperature, humidity, air, light intensity, soil, vegetation, etc. all change with altitude. Soil is the substrate for the life of boletus and its host plants. The structure, air permeability, pH, etc. of the soil are closely related to the growth of boletus.
