New growths on mushroom rock. ID help please.

[bgsca69]

Hello everyone, I just got my lights running again and noticed a couple of new growths om my mushroom rock. Can anyone help me ID these critters? please...

Here's what happened. I suffered a technology crash and my hydra dropped the firmware and defaulted to 10 % power; I had to run them like that for 3 days. When they came back I had these: the first pic looks like the regular discus mushrooms but the edges have small bubbles. And the second one looks like a white fungus bump.

Looks like a white sponge to me = More than fine in a reef tank

Ya look pretty similar to the white sponges I have throughout my tank. Great little water filters for the tank
