The giant puffball is a large fungus, often around the size of a football. It grows on grass verges, field and woodland edges, and amongst rank vegetation. Giant puffballs are saprotrophic, which means they feed on dead organic matter - an important recycling service for decaying plants and other detritus. They usually grow in small clusters, but sometimes form 'fairy rings'. A single giant puffball can produce trillions of spores. They escape through tears in the leathery skin, dispersing on the wind.
What to look for
A very large, often roughly spherical white fungus, with thick leathery skin. The skin becomes browner as it ages. It tends to be around the size of a football, but can grow much larger.
Where to find
Widespread but localised.
