Fungi - Factmonster.com
Fungi grow without sunlight and feed on organic matter. A typical fungus is made of many threads growing on or in a food source. Each thread, called a hypha, oozes chemicals that break down the food. This releases nutrients that the hyphae can soak up. Fungi include MOULDS, mushrooms, toadstools, puffballs, and truffles. About one in four fungi lives in partnership with an alga â€“ these partnerships are called LICHENS.
