Worm?

[Snookster]

A new creature has shown up. I'm guessing some sort of worm. I've checked several id sites, but came up empty. I've never noticed any "appendages" coming out, day or night. They seem to mature at a little over an inch tall and 3/8" diameter. They They don't seem to calcify either.

Any ideas?

Green algae, genus Neomeris.
