During the rainy season in some regions of Japan, are beginning to populated forests of small lights in the trunks of trees and into the moist soil fungi grow hundreds of bioluminescence, which through a chemical reaction produced by an enzyme, emit a light that shines on a greenish ton

The reason for the phenomenon of still bioluminescent fungus has not been explained scientifically, but according to the theory, is believed to be a response to the need for survival: to shine, attract insects that help disperse spores in an environment where the dispersal by wind is very limited.

Luminescent fungi, grow only in native forests with lots of trees, where humans have interfered very little, so its discovery is relatively fairly recent.
