Lycoperdon perlatum, the common puffball, is a widespread species of
fungus in the family Agaricaceae. It forms an off-white medium-sized
puffball tapering to a wide stalk, 1.5 to 6 cm (0.6 to 2.4 in) wide by
3 to 10 cm (1.2 to 3.9 in) tall. Its top is covered in short spiny
bumps that are easily rubbed off to leave a net-like pattern on the
surface. When mature it becomes brown, and a hole in the top opens to
release spores in a burst when the body is compressed by touch or
falling raindrops. It is edible when the young internal flesh is
completely white, but can be mistaken for an immature fruit body of
several poisonous Amanita species. L. perlatum can usually be
distinguished from similar puffballs by differences in surface texture.
Its chemical compounds include the unusual amino acid lycoperdic acid
and volatile sterol derivatives that give the puffball its flavor and
odor. Laboratory tests indicate that extracts of the puffball have
antimicrobial and antifungal activities.
