Is there a way for you to get a better picture? Kinda hard to tell from these. Are only the blades showing, or do you see "roots" at the base of them?

Hard to tell from the pics, daylight pics would help too. Google Dictyota and compare, might be that.

Definitely going to need clearer photo to be able to ID this one..
