'''''[[Caloplaca saxicola]]''''' is a small bright orange crustose [[lichen]] that grows on rock all over the world, including [[Antarctica]]. It is commonly called rock firedot lichen, jewel lichen or rock jewel lichen. It has short, inflated looking elongate 1–2 mm and .3-.1 mm wide lobes that have an abrupt margin at the edge, and no prothallus.  | |||
''C. saxicola'' is one of the few [[lichen]]s found in [[Westarctica]], and is likely the most southerly plant life. The [[Caloplaca Hills]] were named for this lichen, which grows on the rocks there. This lichen occurs over a portion of northern North America as far north as the Canadian Boreal forests, where Black Spruce is a dominant tree. In California, it is one of the most common saxicolous lichens.  | |||
