Do the white spots appear to be moving around like a worm or definitely a part of the mushroom?

When corals are devoid of their symbiotic Zooxanthellae they are transparent or opaque white. With the mushroom being new to the tank it could be adjusting to more intense lighting by ejecting zooxanthallae which is leaving the white spots.
