Shroom ID

[NewReefer455]

Picked this up at the lfs a few weeks ago. I never buy anything without researching first but, with just being a mushroom, I figured I couldn't go wrong as it was cheap and I liked the look of it. I'm new to the hobby in general, but even more unfamiliar with corals. I would assume just a plain blue rhodactis? How do these tend to propagate? Since I've gotten it, it has starting sprouting a bubble out of the top. Will that eventually migrate off as a new mushroom, or is that just a common growth? Thanks in advance!

Hard to tell with that blue lighting. Looks like it might be some flavor of ricordia
