2 Sponges? or Corals? for Id

[stu]

I got these 2 on a few pieces of live rock i recently purchased.....I have no clue at all what they are, i've searched....but it's hard to search for something when you have no clue what it is. The pics aren't the best but i'm pretty sure someone will know what these are. I've seen them before but i can't think of what they are called to search for them.

Thanks for any advice

Both look to be mushroom corals: First pic possibly Rhodactis and second pic of Actinodiscus.

Yup... agree. Mushrooms of some sort.
