A macroscopic fungus with a fruiting body (also known as a sporocarp). It has been estimated that over 1,500,000 species of fungi exist on the Earth; yet only about 69,000 species have been described to date. Approximately 14% (10,000) described species of fungi are considered mushrooms. Mushrooms grow aboveground or underground. They have a fleshy or nonfleshy texture. Many are edible, and only a small percentage are poisonous.
