Algae ID if possible?

Hey guys, just seeing if any one can put a latin name to this algae.
As far as i know, it is a form of sea lettuce but not totally sure.
I put in the original and this came from it as well as the normal form.
It grows to suit amounts of nutrients and my system is semi eutrophic,so there are always heaps of nutrients for these types to feed on. This ribbon form is only on the floor, as it grows closer to the light it is basically the same as the normal sea lettuce. It has no strength as it comes a part if touched and is not very well attached to the glass floor, I don't use substrates.
It harms nothing and grows over nothing at all,only bare areas.

This is it.

Looks like an Enteromorpha sp.

I'll second that. That was my first impression when I saw it.

Thanks guys, much appreciated. I wasn't sure whether it was a sea lettuce or not. Love the sea lettuce for helping balance my nutrients, but when I found a tiny piece of this shaped one on a collecting trip, I just wasn't sure, though in the aquarium it acted the same. I had it doing so well in both display tanks when we had a cyclone and three days with no power killed many of my algae forms, they are all just starting to come back, Lucky I keep spares of all algae I keep in my tubs to start it again. With out these algae along with all the other algae forms to control my waters nutrients at 100 percent, I would be worrying about my sps.
