Far out, man! Scientists figure out why some mushrooms glow


If you think you see a glowing mushroom, you might not be having a psychedelic hallucination. Some mushrooms indeed are bioluminescent, including one that sprouts among decaying leaves at the base of young palm trees in Brazilian coconut forests. Scientists have long wondered what possible reason there could be for a fungus to glow. They now have an answer. Researchers said on Thursday that experiments in Brazil involving the big, yellow mushroom called "flor de coco," meaning coconut flower, showed its nighttime bioluminescence attracted insects and other creatures that could later spread its spores around the forest. "Our research provides an answer to the question, 'Why do fungi make light?' that was first asked, at least first asked in print, by Aristotle more than 2,000 years ago," said biochemist Cassius Stevani of Brazil's Instituto de Química-Universidade de São Paulo. "The answer appears to be that fungi make light so they are noticed by insects who can help the fungus colonize new habitats."
