“Gold dust” lichen is very distinctive

But you need to rule out Candelaria and Candelariella, which can be very similar color, but should have at least some noticeable in-tact lobes. Chrysothrix is entirely made up of powdery granules. Chemistry, size and texture of granules and substrate are used to distinguish the species, but I don’t think the genus is well-known anywhere in the world. It really needs molecular methods to verify any chemical or morphological patterns you may detect.
