Foxfire, also called "fairy fire" is a crazy glow in the dark fungus. The bluish-green glow is attributed to
luciferase, an oxidative
enzyme, which emits light as it reacts with
luciferin. It is widely believed that the light attracts insects to spread spores, or acts as a warning to hungry animals, like the bright colors exhibited by some poisonous or unpalatable animal species. Although generally very dim, in some cases foxfire is bright enough to read by.
