Dichanthelium lanuginosum (Panic grass) is a species of grass. It grows in geothermal areas of Yellowstone National Park, USA. It is able to withstand high temperatures and high acidity in its rhizosphere.[1] In 2007 it was found that the heat tolerance is conferred to the grass by a symbiosis between a fungus and a virus. When it is colonised by the fungus Curvularia protuberata and the fungus is in turn colonised by a particular virus, the grass is able to tolerate soil temperatures of up to 65°C that would otherwise be lethal.[2]
