What in the world is this?

[TakeitEasy]

I bought this beautiful piece from a local reefer. Does anybody recognize these mushrooms. I know they’re ricordia, but does anybody know their type?
There is also another coral attached to this rock I have no idea what it is and neither did the owner(BottomLeft). Can someone help me out here? I’d like to know how to care for it.

The stony coral attached to the rock is Pavona, possibly P. varians

Purple mushroom is yuma, green is a rhodactis.
