Gold dust lichen

Chrysothrix sp

Description:

Chrysothrix is a lichenized genus of fungi in the family Chrysothricaceae.[1] They are commonly called gold dust lichens or sulfur dust lichens,[2]:253 because they are bright yellow to greenish-yellow, sometimes flecked with orange, and composed entirely of powdery soredia.[3] Apothecia are never present in North American specimens.[3] They grow on bark or rocks, generally in shaded habitats.[3] They can sometimes be mistaken for sterile specimens of Chaenotheca, which usually has pinhead apothecia on tiny stalks, or Psilolechia, which usually has small, bright yellow apothecia.

Habitat:

Growing on the North side a of a 12 inch dia. deciduous tree.

Doesn't look like any Xanthoria parietina I have ever seen. I don't see any large apothecia present and there are usually many for a lichen this large. Take a look at Chrysothrix maybe
