i aquired this piece a couple weeks ago from my lfs. i have no clue what it is. it is, without a doubt, the most gorgeous green piece of sps i've ever laid eyes on. any information will be greatly appreciated.

Looks like Hydnophora.

 

[Frankenpora]

Hydno for sure, be sure to keep away from your other corals. It has a potent sting.
