What is it?

not sure of the exact place this belongs. But this coral was given to me a few years ago. I have no clue as to what it is. Not the prettiest coral. As far as I remember, i dont think ive ever seen polyps either. I think i remember hearing it a “cup” coral. But after googling it im not quite sure. It can hold water in it like a regular household cup though! Lol ive always kept it in the back of my tank and it doesnt really go with the rest of my tank.

Not 100% but I think that's a Turbinaria, if thats spelled right
