Placopsis gelida, a lichen, has a circumpolar arctic and temperate distribution in the Northern and Southern Hemispheres. In North America, it ranges along the coasts from the arctic south to the White Mountains in the east and to California in the west. There is an outlier in the moutains of Idaho. It grows on rocks and sometimes on soil in cool, humid, oceanic environments (Thomson 1997).
