Calvatia craniiformis, commonly known as the brain puffball or the skull-shaped puffball, is a species of puffball fungus in the family Agaricaceae. It is found in Asia, Australia, and North America, where it grows on the ground in open woods. Its name, derived from the same Latin root as cranium, alludes to its resemblance to an animal's brain. The skull-shaped fruit body is 8–20 cm (3–8 in) broad by 6–20 cm (2–8 in) tall and white to tan. Initially smooth, the skin (peridium) develops wrinkles and folds as it matures, cracking and flaking with age. The peridium eventually sloughs away, exposing a powdery yellow-brown to greenish-yellow spore mass (the gleba).
