Dichanthelium lanuginosum is a species of rosette grass native to North America. It is most common in the central and eastern United States. It is found in a variety of habitats, mostly in open, dry areas.[1]
A variety, D. lanuginosum var. thermale, grows in geothermal areas of Yellowstone National Park, United States. It is able to withstand high temperatures and high acidity in its rhizosphere.[2] 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.[3] Due to the distinctiveness and isolation of this taxon, it is sometimes considered to be a separate species: Dichanthelium thermale.[1]
