Volvariella volvacea is called Volvariella volvacea because of its golden color and slender shape. This is an artificially cultivated fungus. At present, fresh products are about 100 yuan per catty, and dried products are about 65438 yuan per catty. It is said that Volvariella volvacea is an artificially cultivated fungus, but it has high medicinal value. Because it contains ingredients such as cordycepic acid (I don't know whether it is true or not), it has certain health care functions, such as improving immunity.
