Calvatia gigantea - Giant puffball




  Calvatia gigantea development occurs around the fall months of the year. Puffballs occur in areas of sparse vegetation, such as fields, pastures, and wooded areas. Calvatia gigantea is widespread and locally common in areas of the north due to the favorable temperature zones. Calvatia gigantea is mycorrhizal. The fungus has a mutualistic association with the roots of the plant that it is using as a host.
