What is calvatia booniana?

Calvatia booniana is a species of fungi in the family Agaricaceae. It is commonly known as the giant puffball or the boonian puffball, and it is found in North America. The fruiting bodies of the fungus are large, spherical, and can grow up to 70 cm in diameter. They are covered in a white to yellowish-brown outer skin that cracks open as the puffball matures to release its spores. It is an edible species and is used for culinary purposes in some cultures. However, it is important to harvest it when young and the flesh inside should be pure white, as mature specimens can contain larvae and spores that can cause respiratory irritation. Calvatia booniana plays an essential role in the ecosystem by aiding in the decomposition of organic matter.
