The picture is very fuzzy,

The picture is very fuzzy, but I wonder if this is not a lichen at all, but the alga Trentepohlia (perhaps T. abietina, which often grows on tree bark). Trentepohlia does not have a coherent thallus structure like lichens, but grows in cushions of filaments. With a lens you should be able to see the filaments easily, but you will need a microscope to ascertain the species. Any chance of a sharper picture?
