There is at least one, Ill look for more for you... The Southern Oregon University environmental studies and biology faculty will share their discovery of a new species of mushroom that grows underwater - the first of its kind - in a presentation tomorrow in Ashland, Oregon. The new species is called Psathyrella aquatica http://www.cryptomundo.com/cryptozoo-news/uw-mushrm/

1) "Scientists say they've discovered a new species of mushroom living right here in Southern Oregon. "Unheard of," is what scientists from Southern Oregon University are saying about a new species of mushroom they've discovered living underwater in the Rogue River. If you look north of Prospect, about a foot and half deep in the cold, flowing waters of the Rogue River, you might see a mushroom that scientists say you won't find anywhere else. "Psathyrella Aquatica: the first known gilled underwater mushrooms in the world," said Scientist Robert Coffan. Scientists have identified about 600 similar species of gilled mushroom, but none that live underwater. Coffan says he didn't set out to find a new species, in fact, he says he was just playing in the water on a family outing. "I was up in the middle of July, 90 degrees outside, wading around in the water, enjoying myself, and I saw mushrooms growing underwater," he said. After making the discovery, Coffan and a team of biologists from SOU spent nearly three months observing the mushrooms. He says they develop and mature near other aquatic vegetation and remain constantly underwater. He says he's seen the mushrooms spread over about a quarter-mile stretch, growing on wood, gravel and the silty riverbed. Coffan says this is the type of discovery he'd expect to find in the Amazon, or the bottom of the ocean. "We've identified a brand new species and a brand new habitat right here in our own backyard,” he added. Coffan and his team say they're unsure how significant the discovery is. They say finding a new species in a relatively well-explored area underscores the importance of preserving our natural resources."

He brought the fruiting bodies to Jonathan Frank and Darlene Southworth, Department of Biology, Southern Oregon University. They went with him in 2007 and observed fruiting bodies in the main channel, constantly submerged, near aquatic vegetation. We observed them fruiting over 11 weeks. These appear to be truly underwater mushrooms and not mushrooms fruiting on wood recently washed into the river. Substrates include water-logged wood, gravel, and the silty river bed. DNA sequence data of the ITS region and a portion of the 28S ribosomal DNA gene place this fungus in Psathyrella sensu stricto near P. brooksii and P. gracilis. Based on molecular and morphological evidence, we conclude that the underwater mushrooms are a new species and have a manuscript under revision with Mycologia to describe it. Submersion under water constrains spore dispersal. Spores were observed as wedge-shaped rafts released into a gas pocket under the cap. Underwater formation of normal gills and ballistospores indicate a recent adaptation to the stream environment. This particular river habitat combines the characteristics of spring-fed flows, clear, cold, aerated water with woody debris in shallow depths on a fine volcanic substrate. The presence of nitrogen-fixing cyanobacteria near fruiting body attachment sites suggests a source of nitrogen in an otherwise clear stream. This observation adds to the biodiversity of stream fungi that degrade woody substrates."

You might even know about Oyster mushrooms. These do not grow underwater. Instead, these mushrooms, which are also carnivorous, grow on the sides of stumps and tree trunks and eat tiny insects on the tree. Click here to see a picture of oyster mushrooms. Please remember that the answers to all of these questions refer to the underwater carnivorous mushroom. " Source and further information: http://library.thinkquest.org/CR0210262/mushroom.htm#oyster
