Coral identification help!

[AxeMedix15]

Hey! Im new to saltwater tanks and a gentleman at a local fish store gave me a couple of corals for free. I have some GSP which is flourishing, and the other type, I cannot for the life of me remember the name he told me! It seems to be doing well also but I just want to make sure im caring for it appropriately! I think its actually a mushroom?? Any help is appreciated!!

Photos are dark, some in white lights would be beneficial but what I can make out from squinting looks like a mushroom.
