Definition
Noun: A large, dense cloud of debris, smoke, and vapor that rises into the atmosphere following a very large explosion, most characteristically a nuclear detonation. Its name derives from its distinctive shape, which features a vertical column (the stem) and a wide, spreading, rounded top (the cap), resembling a mushroom.
Usage

It is most strongly associated with nuclear explosions but can also, though less commonly, describe the cloud from very large conventional explosions (e.g., volcanic eruptions, massive industrial accidents).
