lichen at last!

Haha, I agree with Tim here, this really does look like a lichen. There are several screwy crustose things that are light-green and composed entirely of granules and/or minute finger-like isidia. Lepraria is the typical genus, but the isidiate one is… Loxosporopsis corallifera? There are others, too. Look for small black disks, as well. There are some Bacidia, Bacidina, Lecidea and Trapelia(?) that do this sort of thing, but they almost always have some apothecia. Probably others, too.
