Puffball releasing spores

puffball1

During my walk today, I saw a couple of these cute little mushrooms, puffballs, growing out of a cushion of moss at the base of a tree. When I poked them with my finger, a cloud of spores would be released thru the opening at the top. I took about 20 shots, but only one of them captured the spore cloud.

What triggers the release of spores when there are no photographers around? Perhaps, a heavy enough animal stepping on the "ball" of the mushroom? Or, a strong wind?
