Cameronia tecta

Cameronia tecta is a species of crustose lichen in the family Cameroniaceae. It forms a thin to moderately thick, pale beige-brown to greyish-brown crust on rock, typically found in sheltered crevices and overhangs. Unlike the related Cameronia pertusarioides, which grows on exposed dolerite, this species occurs on quartzite and other metamorphic rocks. It is known only from alpine sites in southwestern Tasmania.
