Glow-in-the-dark mushroom rediscovered after 170 years
Spotted once in 1840 and then never seen again, one of the world's most bioluminescent mushrooms has been rediscovered deep in the Brazilian wilderness.

It's something you would never expect to go missing, but one of the world's brightest glow-in-the-dark mushrooms has been rediscovered after an absence of more than 170 years, according to USA Today.
The bioluminescent shrooms had become a Brazilian legend of sorts. They were first spied in 1840 by an English botanist named George Gardner, who was alarmed after he saw some boys playing with a glowing object in the streets of Vila de Natividad, a village in the Goiás state in central Brazil. After that, no more sightings of the brightly glowing fungus had ever been reported.
The mushroom was nearly forgotten until 2002, when Brazilian chemist Cassius Stevani came across Gardner's early reports. Then, in 2005, a breakthrough occurred. A pair of primatologists, Patricia Izar from São Paulo University in Brazil and Dorothy Fragaszy of the University of Georgia in Athens, were studying a band of monkeys deep in the Brazilian interior when they came across something mysterious glowing at the base of some palm trees.
Izar and Fragaszy scooped up specimens and contacted Stevani, who later confirmed that the mushrooms were indeed Gardner's long lost species. The findings are what led to this month's paper in the journal Mycologia.
Ironically, right after the rediscovery of the mushrooms, scientists came to learn that local people were quite familiar with them. In fact, the mushrooms had a common name, flor-de-coco, or flower of the coconut, since it is commonly found on the rotting fronts of dwarf palm trees. As is often the case, scientists had just never bothered to ask.
Although glowing fungi are nothing new to science — there are 71 identified species — this particular species (named Neonothopanus gardneri, after the initial discoverer) is notable for its size and the extraordinary strength of its light.
"It glows more brightly than almost all other luminescent mushrooms," said Dennis Desjardin, a fungi expert at San Francisco State University. "If you were in a dark room and you put one on a newspaper, you'd be able to read the words."
Desjardin also noted that these mushrooms can grow up to three inches in diameter, which is giant compared to most bioluminescent fungi.
Stevani is currently working to identify the chemical pathways that allow these mushrooms to produce light, a system that remain a mystery to science. As for why they glow, scientists still aren't sure why it happens. One theory suggests that the mushrooms may glow to attract insects that help to spread their spores. Another theory, also involving the attraction of insects, proposes that the light is a beacon to predatory bugs that feed on insects that threaten the fungus.
One thing researchers are certain of, however, is that these mushrooms are poisonous. So while the mushrooms' glow-in-the-dark properties may be interesting to people, researchers strongly advise that they shouldn't be eaten.

Great idea for a post.Thank you!
Racism? in Mushrooms?? What??? He had the balls to claim it and name it... Who named America after a Spanish merchant? The nerve...
"Spotted once in 1840 and then never seen again", then later: "scientists came to learn that local people were quite familiar with them". Which is it?
what is gluten at http://www.aboutgrain.com/
And they didn't think to ask the locals after the written account spoke of him seeing locals play with it? These people MUST be scientists.
its like avatar .0.
I want a whole row of these growing on a path!! Natural lighting at night!!!
Amazing
The glowing attracts attention, but also a warning sign..interesting.
i think i ate those at a greatful dead show.............. not but i bet the trips gotta be awsome
what trip, the trip to the emergency room?
I like how it was named after the first white guy to see it, rather than named after the native people that have known about it for HUNDREDS OF YEARS!!
I love science, but sometimes it is VERY racist!!!
the first scientist, not just the first person to see it
What does a mushroom have to do to get noticed around here? They have only been providing light bright enough to read in the dark in all the 170 years that nobody could find them.
fine
Scatter those on an open field and watch people's reactions when they see it.
ive seen this in skyrim. not impressed
glowing shrunes.
Skyrim!
Yes, US have them too, it's the Jack-o'-lantern, and they are poisonous also.
Who wants to go find these? Bet that'll be a trip like never before
I have found Glow in the dark mushrooms in minnesota similar, maybe the same as these the last two summers. They grew on rotting birch.
Very, very cool :D
Reminds me of the spectacular forests in Avatar.
They are just trying to prevent people from eating it so to keep all of its secrets to themselves. I bet it transports you to other worlds.
