mushroom corals

Hello. I just got this mushroom in a trade today and they did not have a name for it. The picture they sent me was under white lights so it looked completely different from mine since I run mostly blues. Is it what I think it is or...

Hi guys Mushroom Corals should not care about kh since they are softies....however, everytime I raise my KH slowly to 10 up from 8.5 for SPS growth I will get shrooms that detach and the others don’t expand as much either. Has anyone else experienced this? Thanks for your help.
