Algae looks like mold???

My tank has been going since Saturday. It was seeded with LS from my LFS, and I put in some large dry rocks, which had some very cool coloring. They said they were dug up and simply dried and that I needed to rinse them first. I rinsed them very well before putting them in the tank. Today I notice this stuff that looks like mold on the rocks. Am I to assume that it is the start of algae growing?

Here is a close up, what you do think?



If you cannot tell where I am talking about, go to my Flickr page. I have boxes around the area where it is at. You can also see a larger image there.
