Least Puffball

Bovista pusilla

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

The Least Puffball faces severe decline due to habitat destruction from agricultural intensification and urban development across its limited European range. Grassland conversion and the widespread use of nitrogen fertilizers have dramatically altered the nutrient-poor soils this species requires for fruiting. Climate change compounds these pressures by shifting precipitation patterns that affect the delicate moisture balance needed for spore development and dispersal.

Threat summary

Habitat

The Least Puffball inhabits nutrient-poor, calcareous grasslands and chalk downs across scattered locations in Europe. It requires well-drained, alkaline soils with low nitrogen content, typically found in ancient pastures and unimproved meadows that have remained undisturbed for decades.
