When we think of plants, most of us will think of the things that grow from the ground and have leaves, but there are plants that do not look or act like other plants．Some of these belong to a special class of plants called fungi(真菌).Fungi may appear almost everywhere．They commonly grow in damp places where they can get food and water easily．Because fungi do not have green leaves, they can not make food for themselves．Green plants use their leaves to make their own food, but fungi must take their food from animals, other plants or waste matter．Some fungi live on dead or rotting wood, while others grow on living trees or in dirt or moss.
Mushrooms are the best-known fungi．There are many kinds of mushrooms in all shapes and sizes．For example, cauliflower mushrooms are found in forests from July to October．They can grow to be as heavy as fifty pounds! They commonly grow at the foot of trees.
Squirrel’s bread is another kind of wild mushroom．Its appearance and use explain the origin (起源) of its name．These fungi, look like small golden cakes, grow on short, fat stems．Squirrels can easily nibble (啃) them or carry them off to their nests to eat later.
The mushrooms found in food stores are carefully grown by people who know they are safe to eat． Mushroom experts warn people never to touch or taste wild mushrooms because some of them are deadly．Even less dangerous ones still make a person very sick.
