Here is a pic of mine:
I totally agree, I was thinking it was more like a pagoda coral or something at the store. They have one in their display tank which has been in there awhile and is just starting to encrust. It looks slightly different than mine, almost like the polyps are a bit more widely spaced apart which gives it the appearance of being a "mini pagoda" or turbinaria or something. I haven't mounted mine as it was rather pale looking and I was waiting for it to fully color up under my lighting before I start moving it up the water column
Wow that is a terrible photo, but you get the idea
