Live rock algae ID please

Not sure if its an algae, but on my kaelini rock i am getting very small, 2-4 mm sized bubble looking things. Black, in groups of 1-3. Just noticed it poppoing up elsewhere as well.

sorry no pic.

Sounds like bubble algae. I think emerald crabs eat it, but I'm not sure, thankfully that's the one algae I haven't had to fight...yet.

It is also pretty solid.

bubble algae. emerald crabs will eat it but you can also take the rock out and pop them off the rock and discard. If you break them, they will spread. It's not the worst thing in the world but worth the effort to get rid of...

Yeah, don't pop them in the tank. It'll spread like wildfire.
