Pyxine copelandii

Pyxine copelandii is a species of lichen in the family Caliciaceae. It was first discovered on the island of Panay in the Philippines, growing on the bark of broad-leaved trees, and is named in honour of American botanist Edwin Copeland. The lichen forms a thin, leaf-like body with a pale bluish-grey upper surface that is usually shiny and bears scattered, powdery reproductive structures called soredia. Since its original description, it has been documented across a wide geographic range, including Australia, Madagascar, Thailand, Fiji, the Seychelles, and several Pacific island groups....read more on Wikipedia.
