Common Puffball / Warted Puffball

Lycoperdon perlatum

Group

Puffball

Season

Generally found from summer through autumn, and sometimes into early winter in milder climates.

Habitat

Typically found growing terrestrially on the ground in a variety of habitats, including woods, meadows, roadsides, and lawns. It can be found solitary, scattered, or in groups.

Key characteristics

The fruit body is typically spherical to pear-shaped, 2-7 cm wide and 3-8 cm tall. It is white when young, becoming yellowish to light brown with age. The surface is covered with short, cone-shaped spines mixed with smaller granules, which are easily rubbed off, leaving a reticulated (net-like) pattern on the surface. Internally, the flesh (gleba) is firm and white when young, turning yellowish, then olive-brown and powdery as spores mature. There is a sterile base that is often pitted or chambered.

Look-alikes

Similar species include other puffballs such as Lycoperdon pyriforme (Pear-shaped Puffball), which typically grows on dead wood and lacks the prominent spines. Young Amanita species (especially 'destroying angel' types) can sometimes be mistaken for puffballs before their caps open; however, cutting a puffball in half will reveal a solid white interior (gleba) without any gills or a developing cap.

Ecological role

Lycoperdon perlatum is a saprophytic fungus, meaning it obtains nutrients by decomposing dead organic matter. It plays an important role in nutrient cycling in its habitat, breaking down leaf litter and other organic debris.
