What is mycena chlorophos?

Mycena chlorophos, also known as the "night-light mushroom" or "green-staining fairy helmet," is a bioluminescent fungus that is native to tropical and subtropical regions of Asia, Australia, and the Americas. This mushroom is known for its unique ability to emit a greenish glow in the dark, especially when disturbed or crushed.

Mycena chlorophos typically grows on decaying wood or leaf litter in moist, humid environments. It has a small, bell-shaped cap that is usually less than 3 centimeters in diameter, and a slender, fragile stem that is often less than 5 centimeters tall. The cap of this mushroom is translucent and sticky when wet, and can range in color from white to pale green.

The bioluminescence of Mycena chlorophos is thought to be produced by a chemical reaction involving luciferin and luciferase enzymes, which are commonly found in bioluminescent organisms. The glow is believed to serve as a defense mechanism to deter predators, attract insects for spore dispersal, or communicate with other fungi.

While Mycena chlorophos is not considered toxic to humans, it is not recommended for consumption as it is difficult to positively identify and there is a risk of confusion with toxic lookalike species. Additionally, the bioluminescence of this mushroom is relatively weak and may not be visible in brightly lit areas.
