Coral ID, Please

I was in my LFS buying some water and saw this little frag in their display. They said they've had it for a while but didn't necessarily know exactly what it was. It isn't the prettiest looking frag but kind of reminded of the Charlie Brown Christmas tree so I bought it because it was cheap. The colors are nice. Can someone help me identify it. Is it some type of Favia? Perhaps a strange chalice?

My brain says "Mycedium" but I don't know why?

Echinophyllia aspera, not Mycedium

Looks like "joker" favia IMO
