What's the Name of this Mushroom?

[Shazreef]

I bought this live rock from someone and after about a month I noticed these mushrooms popping up. What's the ID on this?

Seems to be red with blue dots.

Thats a weed coral. They spread very quickly. Personally I would get that rock out of the tank, I would not want those mushrooms

Try to keep the Discos on their own rock and they will look nice once they have multiplied. When they run out of space (or too much flow) on the rock they will start detaching and spreading, but mostly you can pick them up before they really attach to an area that is not accessible.
