Help with an accurate id?

I am very new to saltwater tanks and very new to this site. we acquired some live rock with mushrooms that are reproducing like crazy. I've been scouring the internet and just can't figure out what these guys could be. I thought maybe a bullseye of some sort due to the center. But I'm not sure. Any help would be appreciated

Discosoma mushrooms. They come in a multitude of colors and patterns, are typically very hardy and spready quickly.

The only thing they really don't like is direct bright light and high flow.
