Mushrooms may turn out to be important keys to both human health and planetary health. Their indispensable role in recycling organic matter, especially in forests, has long been known. But how many people realize that trees and other green plants could not grow and reach maturity without symbiotic associations with mushrooms, at least with myceliumThe network of fungal threads in soil that act as interfaces between plant roots and nutrients?菌丝体(mycelium)：由许多菌丝连结在一起组成的营养体叫菌丝体。A mushroom is the reproductive structure or fruiting body of mycelium. Mycelium runs through our world, but it is hidden and inconspicuous---a strange life form thathas not attracted the same scientific attention as micro-organisms or plants or animals.Why Western medicine had never looked to mushrooms as sources of new therapeutic agents, given their prominence in the traditional pharmacopeias of China, Japan, and Korea. The natural competition that exists in soil between mycelium and bacteria. There are more species of fungi, bacteria, and protozoa in a single scoop of soil than there are species of plants and vertebrate animals in all of North America. The History of Fungal NetworksAnimals are more closely related to fungi than to any other kingdom. More than 600 million years ago we shared a common ancestry.Fungi evolved a means of externally digesting food by secreting acids and enzymes into their immediate environments and then absorbing nutrients using netlike cell chains.Fungi marched onto land more than a billion years ago.Many fungi partnered with plants, which largelylacked these digestive juices. Mycologists believe that this alliance allowed plants to inhabit land around 700 million years ago.Many millions of years later,one evolutionary branch of fungi led to the development of animals. The Mycelial ArchetypeThe similarity in form to mycelium may notbe merely a coincidence. most energy-conserving formsmaximize the pooling of data and computational power while minimizing critical po
