Elegant sunburst lichen
The elegant sunburst lichen (Xanthoria elegans) is a lichen recognizable by its bright orange or red pigmentation. This species grows on rocks, often near bird or rodent perches. It has a circumpolar and alpine distribution. It was one of the first lichens to be used for the rock-face dating method known as lichenometry.Photo: Jason Hollinger
