Mushrooms are small living things that look like umbrella. They are not plants because they do not have the green material that plants use to make food. Mushrooms get their food from the living or dead plants around them.
A mushroom has two parts: the mycelium（菌丝体） and the fruit． Mycelium is underground and gets food for the mushroom. Sometimes it dies quickly, but if it gets enough food it may live for hundreds of years.
The fruit, umbrella-shaped body, only lives for a few days. Gil(菌褶）, small plants under the mushroom's cap, have small spores(孢子) on them． When these spores fall off the mushroom the wind blows them away. If they fall on a warm, wet area a new mycelium develops.
