It's a ball fungus that makes a spectacular puff of "smoke" when you stomp on it. The smoke is spores I guess, but they don't seem super common. I might find less than a handful a year.
Edit:
This is what they look like when they're stompable. This one's a little old, and has already leaked some magic smoke, but it still looks fun :^)

I have a explosion of these weird ass mushroom clusters/pods that grow in a way that they're somewhat buried. Really freaking strange looking, like nothing I've ever seen before.
I got a really long screw driver and poked into one and it was almost like the sound and resistance of a block of styrofoam but organic.
Then came the smell. It smelled like a dead animal with a hint of rotten fish mixed in.
I didn't take any chances and just uprooted them all and strayed the area heavily with a bleach/water mix.
