Algae ID

In addition to some scattered sections of GHA my year old mixed tank has these weird stalks of algae. Looks like bryopsis but without the feathery bits. Possibly young bryopsis? The hair algae is much more fine than this stuff. Ideas?

I apologize for the image quality. Had to enlarge the image a bit to get at these things.

Looks like a form of Chaetomorpha. An urchin would probably mow it down.
