(seen in daylight, top, and in the dark) is the oldest known glowing fungi, identified in the 1800s in Japan
's Bonin Islands.
Ever since, scientists have named any gray fungus that glowed M. chlorophos
--even in the New World, where the species does not grow.

is found only in Southeast Asia. In the process, they introduced seven new species of glowing mushrooms to the world.
