Stumped by a puffball.

Puffballs are fungi that spread their spores by puffing them into the air.  When something touches the outer casing a cloud of minute spores squirts out like a puff of smoke.  This happened when we just gently touched these Stump Puffballs (Lycoperdon pyriforme).  They grow on rotten stumps and logs.
 
 
 They are club-shaped with a little hole on the top for the puff of spores to come out.  Simon found them near post 17.
