mystery coral

I was told that maybe someone could help me identify a coral that I have. I've posted with my local group but nothing has come about yet. Any help would be much appreciated.

What do I have here (big green thing)

About 6 months ago I bought this coral from a local fish store. I was interested in it and asked what it was. The owners didn't know for sure. IIRC it was listed on his inventory sheet as a favites, but just by its appearance it didn't appear to be one. I liked it and I bought it. The overall consensus from people in the store was some kind of sea mat, perhaps.

Spring forward 6 months, the coral is doing well and it looks like the mat is expanding off the rock forming sheets hanging down. So I think, "hey, this is a good time to frag the mat, it will be easy trimming with an exacto knife". Until I start cutting and I realize this mat is not fleshy, it is stony. I few tiny frags broke off, with only one big enough to transplant on a new rock in the frag tank. The entire colony closed up as soon as the small pieces broke off, very rapidly. About 3 minutes later the entire colony opened back up just as quickly. So now I'm left wondering, what is this? Could it be some kind of incrusting monti or in fact a type of favites after all? I've not had much luck locating a match online.

Welcome to the world of montiporas Chad.

Looks like a plating monti. Perhaps a good old green cap.

I am no expert, but that is what I would guess.
 
A monti was my first guess when I saw it was plating. I don't think its a regular green cap. I have a purple rim green cap (can be seen in one of the photos) and the mystery greens polyps are much bigger. But I'm sure different types of monti will have different types of polyps. Anybody know of a site with lots of monti pics?
 
Looks like encrusting Goniopora. I have a red one in my mix reef and the polyps are about 1/8" round. :) Or Turbinaria sp.

Could that be turbinaria? It can take some odd forms, and that whorl characteristic makes me wonder.

Fly this past the sps forum, too.
 
i believe RandyO has something exactly like this, cant remember what he called it tough.. id pm him he'll be able to tell you..
 
Hmm, I know porites, gonis, and montis are in the same family but they have different numbers of tentacles on the polyps or something. Got a magnifiying glass? hehe

I'm still standing by turbinaria reniformis.
and ill second that.
 
I have this question running in a couple of threads, and more pics were asked for in the other one. I'm going to copy that same info here just to see if it will help anyone. They are a little better in quality and in higher rez. Thanks for the help.

Here are some more photos. I left the rez as high as I can so I'll just include the links here. It shows areas of the fully extended polyps, plating areas, and a couple of pics show an area where I got the polyps to retract showing a browish-purplish base.

I cannot really tell from the picture, but it does not look like it has the texture of one of the Astreopora species. Can you get a pic with the polyps withdrawn so that we can see the corallites? I am actually leaning toward some Poritid species just judging from the polyps.
 
If the tissue is thick and fleshy, i believe it is an echinopora. Borneman's book evern says they look superficially like astreapora. He says if the corallites from above look like acros, its astreopora
