Take a midnight stroll through the golden foliage-filled woods this fall and you might discover foxfire, a type of fungus that primarily grows in decaying wood. Also called fairy fire, the fungi creates light during a chemical reaction that occurs when the quick-growing, healthy fungal cells consume wood and the oxidative enzyme luciferase reacts with luciferin. Though air pollution and other factors can affect the foxfire’s brightness, some say the fungus’ bioluminescence is so bright that one could read a book with only the fungus’ light. Foxfire is the informal term for many different bioluminescent fungi including Panellus stipticus, which grows as small clusters of glowing mushrooms.
Now, realize that you are an infinitesimal fraction of half a speck within this image and quit worrying.
