Could someone please ID this coral? EASY

[Joekneebone]

Hey,
I have just purchased a beginner's coral frag pack with 4 corals. I have managed to identify the other corals but there is one I am not 100% sure about.
If someone could tell me what it is that would be great! Thanks!

Looks like closed up Green Star Polyps

hard to tell as i cant really make out the color. if the mat is purple, i would say green star polyps. if its a yellowish color, i would say scroll coral, turbinaria, etc.
