What are these? (pics)

[Molino]

Ok, thought I'd finally get around to trying to ID some of the stuff in my tank. I have some other things as well that I'm not sure about, but I'll get some pictures of them later.

I like the look of this. Some kind of green algea maybe... almost seems to have tiny leaves.


This thing looks cool, but I have a feeling it may not be desirable... Over the last several months it has grown in size. On a side note what is the small whitish thing directly to the left of it?
