Mushroom Cultivation 0 views
Shiitake, also known as xiangxun, xiangjun, or donggu, belongs to the phylum Fungi, class Basidiomycetes, order Agaricales, family Pleurotaceae, genus Lentinula, and is one of the world's famous edible mushrooms. It is mainly distributed in China, Japan, Korea, Vietnam and other countries. In China, shiitake cultivated on logs is mainly produced in Zhejiang, Fujian, Jiangxi, Guangxi, Guangdong, Anhui and other places, while shiitake cultivated on sawdust is mainly produced in coastal areas such as Shanghai, Jiangsu, Zhejiang, Fujian and Guangdong. Morphological characteristics: Shiitake consists of two major parts, the mycelium and the fruiting body, and the fruiting body of shiitake is in turn composed of three parts: the cap, the gills and the stipe.

Morphological characteristics

Shiitake consists of two major parts, the mycelium and the fruiting body, and the fruiting body of shiitake is in turn composed of three parts: the cap, the gills and the stipe.

1. Cap: The diameter is generally 3-15 cm. The color and shape vary with the age of the mushroom, the intensity of light received and differences in nutrition. When young, the cap is hemispherical, and its margin is initially inrolled; at maturity the cap flattens and the edge curls slightly inward, while when overmature it curls upward and back. The surface of the cap is light brown, tea brown, etc., with lighter-colored scales on it, and sometimes with chrysanthemum-shaped or tortoise-shell-like cracks. The flesh is thick and white.

2. Gills: Located on the underside of the cap and arranged radially, white. The surface of the gill plates is covered with the hymenium, on which there are many basidia, and on the basidia are countless basidiospores. The spores are ovoid, smooth and colorless.

3. Stipe: Central or off-center, white. When young, the surface of the stipe is covered with fine hairs (scale-like when dry), and the stipe is generally 2-10 cm long.
