これは「生物発光」と呼ばれます。深い森の中で、特定のキノコは不気味な緑色の光を放って虫を引き寄せます。虫がキノコに触れることで、胞子が遠くまで運ばれる仕組みなのです。

If you walk through a tropical forest at night, you might spot a soft, ghostly green glow coming from the ground or rotting logs. This isn't magic; it's bioluminescence, a chemical reaction that allows certain mushrooms to produce their own light.
Unlike plants that use seeds, mushrooms use spores to reproduce. Most mushrooms rely on the wind to carry their spores away, but those living in the still, windless air of deep forests need a plan B.
This glow is caused by a molecule called luciferin reacting with oxygen and an enzyme. It's the same basic process that fireflies use to light up their butts!
Glowing mushrooms use light as a clever marketing tool. By turning themselves into tiny neon signs, they ensure their offspring can travel far and wide, even in the darkest, most stagnant parts of the jungle.
