Agaricus blazei (scientific name: Agaricus blazei? Murill) is a kind of Agaricus fungus. The diameter of mycelium cap of Agaricus blazei Murill is 5- 1 1 cm, and the maximum is 15 cm, and the thickness of mycelium cap is 0.6- 1.3 cm. It is hemispherical at first, flat at the back and uneven in the middle. The surface is brown with fibrous scales. Mushroom meat is white, mushroom pleats are free, width is 8- 10 mm, white turns black, and white handle is 6- 13 mm long.

With a diameter of1-2cm, it is a mesophyte with a suspensor. The spore size is oval, 65 μ m× 5 μ m, and there is no bud hole. The color of spore imprint is brown. The mycelium is white and fluffy. The hyphae are locked together. Most of the fruiting bodies are solitary, single and clustered, and they are umbrella-shaped when they mature. The fruiting body generally weighs 20-50g, and the largest can reach 350g.

It is hemispherical at first, flat at the back and uneven in the middle. The surface is brown with fibrous scales. Mushroom meat is white, mushroom pleats are free, the width is 8- 10 mm, and it turns black after white. The white stem is 6- 13 mm long, roughly equal in thickness from top to bottom, solid when young and hollow after. With a diameter of1-2cm, it is a mesophyte with a suspensor.
