This is a mushroom of some kind? Yes, its really too bad its so blurry...can you try to go back and get another photo?and take your tripod? Its an awesome fungus!! would love to know more about it..
At first glance it looks like left over snow, not quiet melted. It is rather strange and I don't think I'd like to find it growing in my yard. Would be great to see a clearer picture if at all possible.
That's a type I've never seen. It does look like old, dirty snow or.......a wet mop head. I would have liked to see the spongey details but you take what you can get. Maybe it will form again sometime.
