Hello everyone. I put some live rock in my 30 Gallon and this was attached to the rock. I have this on 2 pieces of rock. What is it? I thought it might be bubble algae but cant match it with pictures online

Need a much better pic, I can't even tell the color of it for sure, or the texture or shape.
