Mushrooms

We've had a fair amount of rain recently, and I haven't been able to help but to notice the sheer abundance of fungi in the yard of my house, my rental, and the woods when I've been running.

I assume the rain and the mushrooms are connected, but, since I know bugger all about nature, since I've spent my whole life focused on first culture and now finance, I really can't be certain. One thing I have noticed, is that there are a lot of mushrooms, and it makes me want to sing the Smurf song.
