Mushroom is the fruiting body of Basidiomycetes fungi. It is also known as basidiocarp. The Basidiomycetes contain two orders called Agaricales and Aphyllophorales. In agaricales, the mushroom or fruiting body is fleshy. it contains parts like stipe or stalk, pileus and lamellae. On lamellae, the basidia produce the basidiospores. The order Agaricales contain members like Agaricus sps, Amanita sps, Cortinarius, Laccaria and Suillus sps. These are edible mushrooms. Some mushrooms are highly poisonous. Order Aphyllophorales contain mushrooms having coriaceous, leathery to woody fruiting bodies and some are fleshy also. The members include Ramaria sps, Pycnoporous sps and Ganoderma sps etc. Since, mushroom is fruiting body, fleshy and edible, thus, picking a mushroom can be similar to \"picking an apple off an apple tree.\" Solution Mushroom is the fruiting body of Basidiomycetes fungi.
