Plate Coral Identification Help

[knappe]

When I bought and moved my tank 1.5 years ago there was a plate coral that took a serious hit. I thought it was dead (the tank was moved in January and the buckets sat in the cold for too long) until I read that they can and do come back over time. So I left the exoskeleton out on a platform of rock and watched as magically new babies showed up and started growing all over the old exoskeleton. Fast forward to today and I just found the first baby to detach from the old exoskeleton and move onto the rock work.

I'm hoping someone can help me identify them as I'm stumped. Based on the pictures I've searched on, it comes up as a "Green Plate Coral" which sounds pretty generic and fairly untrustworthy. They notably don't really look like the adult that was originally moved, but I don't know if that is because they eventually change color as the mature.

Here is what the parent and now exoskeleton looked like before the move in whites:

Here is what the pile of babies looks like today in blues:


And finally, the baby that has detached:


Any help in identifying them would be wonderful. I'm ecstatic that they're finally starting to migrate from the old exoskeleton! Please let me know if y'all need additional pictures or with different lights.

Was the original plate circular or elongated (hard to tell from the first photo)? Do you have any photos of it closed up?

I have seen photos of this morph in greener/siltier environments like Thailand or Singapore; I suspect it is an inflated either Fungia fungites, Lithophyllon (Verillofungia), or Danafungia scruposa.

I'm afraid that is the best picture I have -- that was taken a week before the move. Everything after that shot is really of the exoskeleton. :(

It seems like the exoskeleton was elongated but the actual coral was more circular.

Here is a picture I took afterwards, if that helps

I see, it's hard to tell the shape when the photos are at an angle like that as oppose to head-on.
