Acan/Enchino hybred?

[MammothReefer]

Looking for some held with an id here. I traded for this back in 2005, (it's long gone) the shop I traded for it was a bit stubborn about letting it go, and I doubt has the piece anymore. I'll have to dig around threw my old photo archives to find a picture of the whole piece, but basically while I know this photo makes it look like a standard enchio.. the colony as a whole looks as if you took a huge piece of acan lord, and filled in the spaces between the polyps.

Any thoughts as to what it might be?

you have a couple of options, acan echinata, rotundaflora, or a chalice (echino) variant Without a better picture it will be hard to distinguish

Ya, I was thinking along those lines, this was a bit odder though it was almost like an encrusting lord. I know the frag of it looks very echinata'ish. I'll see if I can't find another photo.
