A new species of mushroom glows green at night
Beijing Science and Technology News, November 1, 2006: a cluster of mushrooms glows green at night or in dark places in Ribeira Canyon State Park, not far from Sao Paulo, Brazil, according to National Geographic.
There are more than 500 species of fungi in the world, of which 33 species will glow. This kind of mushroom is one of the newly discovered species that glow. During the day, this mushroom is inconspicuous, but at night, chemical reactions make it emit a soft and strange green light, sometimes called "fox fire".
Since 2002, Cassius Stevani, a professor of chemistry at the University of Sao Paulo in Brazil, Dennis de Yardan, a professor of mycology at San Francisco State University in the United States, and Marina Capella of the Brazilian Institute of Botany have discovered more than 10 species of luminous fungi one after another, four of which were found in the Brazilian rainforest. Their work has increased the number of luminous fungi by 30% since the 1970s.
These 33 luminous fungi belong to 16 different lines, and one can't help but ask: have fungi evolved 16 times or only a few times in the process of evolution? To find out, de Yardan's team began to extract DNA from luminous mushrooms and sequence DNA.
