Two varieties of algae growing on my LR - Bryopsis?

[navigator]

This LR has been in the tank for a couple of months now, but these two varieties of algae are new (or were sufficiently hidden in the green-hair that's since been removed). I'm still calling them hitchhikers. Any thoughts? (see green branching variety in the lower left of the first pic, and those odd leafy ones near the hermit in the both pics). Keep in mind that this is zoomed way in - these are tiny.
Bryopsis? It hasn't changed size after a week or two. Other ideas? The second might be Caulerpa - can anyone verify that?
