Bioluminescent fungi are a fascinating group of fungi that emit light through a chemical reaction. This natural glow is primarily due to a compound called luciferin, which, when oxidized, produces light. These fungi can often be found in damp, decaying wood or forest floors, where they play a role in breaking down organic matter. The light emitted by bioluminescent fungi can vary in color, typically appearing green or blue. Some well-known examples include species from the genus Mycena and Armillaria. This bioluminescence may help attract insects, which can aid in the dispersal of spores, contributing to the fungi's reproductive success.
