ID on disk shape algae

[jonny1972]

I've looked on RC for this and on the net...no luck. Maybe one of you can help me. I've notice a small, about an 1/8'' disk shaped algae growing in my tank. It's very simular to a zo with a green outer rim and a white spot in the center with a green stalk. It does not form a matt each one grows as a single plant and has spred on the LR. I wish I could take a pic to help out with the ID but a have no way of doing this.
Any help would be great thanks.

Hi jonny1972,

Try looking up acetabularia.
