The Propeller Mushroom, scientifically known as *Mycena chlorophos*, is a small, bioluminescent fungus found in tropical and subtropical regions. It typically grows on decaying wood and is recognized for its distinctive, propeller-like shape. The mushroom emits a greenish glow in the dark, which is a result of a chemical reaction within its cells. This unique glow attracts insects, which help in the dispersal of its spores. The Propeller Mushroom is part of the larger family of Mycenaceae, which includes various other small mushrooms. While it is not commonly consumed, its bioluminescent properties have intrigued scientists and nature enthusiasts alike.
