You have a puffball! Is it brown, with a
purplish-grey or purplish-black center?

Very young ones can be white inside, but still often have a tinge of purple near the center. The outside can be bumpy or smooth. These puffballs are in the genus Scleroderma, and are Mutualists with nearby trees.


The insides may be white, brown, or black, often with olive tinges, but not purplish. These puffballs are Saprobes, feeding on dead soil matter.
