A simple plant with no leaves, flowers, or the green coloring matter chlorophyll. Fungi (the plural of fungus) include all kinds of mushrooms, yeasts, molds, mildews, toadstools, and rusts. Because fungi have no chlorophyll to make their own food, they usually feed upon dead or decaying plants and animals. Some kinds of fungi have only one cell, while others are a mass of threads called hyphae. Fungi usually reproduce by sending out tiny spores that grow into new plants.
