Any idea?

I just re-arranged my LR a week ago and this one rock has has started to grow a blueish-grey fungus looking film (like what you'd see on a rotting orange skin) and clue what this could be?
Meant to take a picture before lights went out but had to put the kids down.
Will post a picture tommorrow, but thought I'd ask incase someone may know.
I'm thinking it may be the start of some kind of sponge. There are several yellow and purple colored sponges under some rocks.
