Id please: Green Bulbs

Could someone ID this for me?

I tried siphoning it out, but it's still growing. Looks like some kind of cocoon with a translucent green coating.

I believe they are some sort of calcerous macroalgae. I wouldn't worry about them too much.

It sure looks like something devastating is about to hatch and destroy everything.

If you don't want it, I take it.. I like macroalgae

There's only a few, but I'll save some for you next time I clean it out.

I had them as well. It was weird because they just started sprouting out of the rock after my tank crashed. There was a small patch of these along with a lot of hair algae. However, now that the hair algae is almost gone, this macroalgae is gone as well.
