Mushroom ID?

[Renelope]

Hey folks,

We purchased a new piece of live rock today, and it had a mushroom coral on it, got it into the tank but am not sure on ID... any help? I want to be sure I'm placing it in a good spot so it doesn't die.

Thanks!

Looks like a rhodactis, but it's pretty closed up so it is a guess....does not look like discoma even closed up though.

I know I wish I would have taken a picture while we were in the store, fully open he was pretty big!

He opened up a bit more before dark... I also noticed 3 tiny mushrooms next to it that were closed up when we got home...
still not positive on an ID
