Wildlife Spotting

I haven't a clue what this may be. I found it on the side of a an old tree stump. Could be some egg pack of something, could be a fungus. It's yellow, really bumpy, and a little larger across than a quarter. It's also in my yard near where the kids play.

Ok, I'm fairly certain it's a slime mold of some sort. Day 1 it was the bumpy yellow patch. Day 2 it looks like dark brown piece of branch, only really soft and there's what looks like snail slime around the base. There's also a second patch that is the same brown, but grew out that looks like hair.
