Bioluminescent fungi (Mycena chlorophos)

No, you’re not hallucinating; you really are seeing bright green mushrooms, but if you are partial to the odd magic mushie, these images won’t faze you in the slightest. These neon green mushrooms, or Mycena chlorophos, to use the technical term, emerge during the rainy season in Japanese and Brazilian forests, scattering the floor with glowing spores. The bases of tree trunks, fallen branches, leaf litter and moist soil provide perfect breeding grounds for the mushrooms. Found mostly on Mesameyama island in Ugui, Japan and Ribeira Valley Tourist State Park, Brazil, the appearance of these garish looking fungi is due to bioluminescence, one of the weird but wonderful reactions that happen naturally in many plants and animals.
