Mycena chlorophos (seen in daylight, top, and in the dark) is the oldest known glowing fungi, identified in the 1800s in Japan's Bonin Islands.
Found just once in southern Brazil, the glowing Mycena abieticola mushroom (seen above in daylight, top, and at night) had previously been identified in Mexico where it grows on fir trees.
The mushroom Mycena silvaelucens, whose Latin name means "forest light," (pictured, in daylight, top, and at night) was discovered on the grounds of an orangutan rehabilitation center in the Malaysian section of the South Pacific island of Borneo.
Glowing nonstop in the Brazillian rain forest, the newfound mushroom Mycena luxaeterna (pictured both in daylight, top, and in the dark) is indeed a source of eternal light, as its Latin name--inspired by verses from Mozart's "Requiem"--implies.
