Cloud ear

Tremella fuciformis is a kind of edible fungus with rich nutrition, and it is also a traditional health food and export commodity. It has many aliases, because it grows on rotten wood and looks like a human ear, so it is also called auricularia auricula; It is also like a moth butterfly, also known as a wood moth; Because it tastes as delicious as chicken, it is also called tree chicken and wooden machine (the ancient South Chu people called chicken a machine): double-petaled fungus is embedded in the tree, just like pieces of floating clouds, and it is also called cloud ear. There are mainly two kinds of auricularia auricula that people often eat: one is that the ventral surface is smooth and black, while the back is hairy and gray or grayish brown, which is called auricularia auricula (commonly known as wild auricularia auricula); The other is smooth, dark brown and translucent on both sides, which is called Auricularia auricula. Maomu has large ears, but its texture is thick and tough, it is not easy to chew, its taste is not good, and its price is low. Auricularia auricula is soft and delicious, smooth and refreshing, and rich in nutrition. It is a kind of artificial cultivation. Tremella fuciformis consists of mycelium and fruiting body. The mycelium is colorless and transparent, and it is composed of many tubular hyphae with transverse diaphragms and branches. It is a vegetative organ for the decomposition and absorption of nutrients by Tremella fuciformis. The fruiting body is the edible part, and it is the reproductive organ of Tremella fuciformis. The fruiting body is cup-shaped or bean-shaped when it is born, and gradually grows into wavy leaf-shaped or ear-shaped. Many ear pieces are gathered together in a chrysanthemum shape. Fresh fruiting bodies are translucent, gelatinous and elastic, generally 4-6 cm in diameter, and up to 10-12 cm in size. After drying, they shrink sharply into horny, hard and brittle. The fruiting body is divided into dorsal and ventral surfaces, and the dorsal surface (the side attached to the auricularia) is convex and dark blue-gray, with many soft short hairs (the characteristics of which are very important in the classification of auricularia auricula), which do not produce basidiospores. The ventral surface is concave, the surface is smooth or veined, dark brown or brown, and the surface is densely packed with neatly arranged basidiospores when mature. Observing under the transverse microscope, the basidiospores are kidney-shaped, with the size of 9-14×5-6μm, colorless and transparent, and many basidiospores gather together to show white powder. After the fruiting body is dried, its volume shrinks strongly, and basidiospores adhere to its ventral surface like a layer of frost. When the dried tremella fuciformis absorbs water and expands, it will restore its original fresh stretched state.
