Coral ID help

[NeuroDoc]

I was hoping that you all might help me ID this coral. When I bought it, the whole plate was covered, but then it fell on my hammer coral one night and I'm left with dead patches.

Do the corallites easily crush when you touch it? If so It may be Galaxea astreata. It's very difficult to tell from the picture. The corallites of this coral are very sharp and short breaking easily when handled.

Playing the guessing game, to me it looks like hydnophora

Its a hydnopora

Thanks guys. I certainly looks like the picture of Hydnophora microconos posted here by MojoReef in the library.

What are the chances that it will re-grow over the dead areas?
