Puffball – Wolf Fart

Q: I’m not sure what these white “eggs” are in my yard. They are out in the open, not clutched together. I don’t know if they are an animal egg or some type of fungus. Can you help me identify them?

A: They are puffballs that have a crazy common name:! The scientific name, Lycoperdon pyriforme, means in Greek “wolf fart pear-shaped puffball” (lyco = wolf, perdon = to break wind, pyriforme = pear-shaped).

These fungi, like all mushrooms, are the fruiting part of a fungus that is decomposing organic matter underneath them.

They are not poisonous.

Gently squeeze one and observe the puff of spores propelled out the top.
