Punctelia reddenda

This gorgeous foliose lichen grows in rosettes up to 6 cm in diameter. The upper surface is gray-green to yellow-green with white, punctiform (point or dot like) pseudocyphella which turn into soralia which produce granular or nodular soredia. The lower surface is black toward the center and lightens to brown near the rounded margins of the overlapping lobes. P. reddenda grows on mossy tree trunks and rock in Africa, Macaronesia, North and South America, and Europe.
