Graphis glaucescens
This script lichen looks less like script and more like the tunnels left by burrowing worms, but that’s ok, they are still beautiful. Those long, distinctive apothecia that give script lichens their distinctive pattern are known as lirellae. The lirellae in G. glaucescens are white or pale gray, oblong, occasionally branched, and particularly curvy. They are scattered across a pale, powdery thallus surface. G. glaucescens grows on deciduous tree bark in tropical regions on either side of the equator. Graphis happens to be the genus with the largest number of known lichen species within it. Go out side, find a smooth-barked tree, and chances are you will find a Graphis lichen growing on it somewhere. And if you are in a tropical area, who knows? It might be this one. (the answer is me. I would know.)
