Lost glow-in-the-dark 'Ghost Mushrooms' rediscovered

​In the lush forests of Brazil, researchers have found a glow-in-the-dark mushroom not seen since 1840. The long-forgotten fungus has been reclassified, but scientists are still trying to determine just what makes the mysterious mushroom glow — and why.

The mushroom's bioluminescence, or an organism's ability to produce light on their own, was first discovered by English botanist George Gardner, who spotted a group of boys playing with a glowing fungus on the streets of Vila de Natividade in Brazil. The boys led him to where it grew at the base of a decaying dwarf palm, and Gardner named it Agaricus gardneri.
