Puffball mushrooms are some of the funniest-looking mushrooms in nature because they are perfectly round and do not have a cap or a stem like other mushrooms. They look like smooth, white balls just sitting on the ground! Puffballs can be as tiny as a marble or as enormous as a beach ball.

Puffball mushrooms grow in fields, forests, and meadows all around the world. The biggest puffball ever found was over four feet wide, which is bigger than most kids! Giant puffballs can weigh as much as 44 pounds, which is about as heavy as a big dog.
