Mushroom ID

[InvaderJim]

Picked up some corals today from a friend breaking down his tank and he gave me this rock with what looks to be three mushrooms that are bright white like they are bleached. The tentacles (for lack of a better word) are nothing like I’ve ever seen before on a mushroom. They actually resemble a rock flower anemone to me.

The green ones appear to be Ricordea yuma, and the pink one is the same species. I'm not sure about the whites though, but if I had to guess they are probably also Yumas but just bleached.

You talking about the ricordea yuma?

Sorry should have been more specific. The white ones closest to the front of the picture

They looked like bleached something, I almost thought they were sponges but the left one clearly is not a sponge.
The left certainly looks like a bleached mushroom of some sort.
