White Mold?

[cam78]

It appears there are small spots of what looks like white mold growing on my LR. There is not a lot of it just small 1/2 inch pieces here and there. The tank has been up and running since January so I don't think its die off. Any ideas? Looks like white little sponges. Proboly can't get any good pics of it though.
