Cameronia pertusarioides

Cameronia pertusarioides is a species of crustose lichen in the small family Cameroniaceae. It forms a thick, pale lemon-yellow crust on rock, often spreading into extensive patches tens of centimetres across. The species is the type of its genus, Cameronia, which was established for distinctive alpine lichens that did not fit any existing genus. It is known only from sun-exposed dolerite rock at alpine elevations in Tasmania.
