Calvatia sculpta, commonly known as the sculpted puffball, the sculptured puffball, the pyramid puffball, or Sierran puffball, is a species of puffball fungus in the family Agaricaceae. Attaining dimensions of up to 8 to 15 cm (3 to 6 in) tall by 8 to 10 cm (3 to 4 in) wide, the pear- or egg-shaped puffball is readily recognizable because of the large pyramidal or polygonal warts covering its surface. It is edible when young, before the spores inside the fruit body disintegrate into a brownish powder. The spores are roughly spherical, and have wart-like projections on their surfaces.

Originally described from the Sierra Nevada, C. sculpta is found in mountainous areas in western North America, and was found in a Brazilian dune in 2008. It may be easily confused with Calbovista subsculpta, a similar puffball that—in addition to differences observable only with a microscope—is larger, and has slightly raised warts with a felt-like texture. Other similar species include Calvatia arctica and immature specimens of Amanita magniverrucata.
