Giant Puffball Fruiting Bodies Appearing

10-14-13 giant puffball 051 The fruiting bodies of Giant Puffballs (Calvatia gigantea) are quite distinctive looking — typically they grow to the size of a soccer ball, but the record specimen measured eight feet, eight inches in diameter and weighed 50 pounds. According to Cornell, it’s been calculated that a single ten-inch Giant Puffball has as many as 7 trillion spores. If each of those spores grew and yielded a ten-inch puffball, the combined puffball mass would be 800 times that of the earth. Look for Giant Puffballs in the fall, growing on lawns, grassy meadows and open woods, sometimes in clusters, sometimes singly. If you find one and it is still white and relatively young, foraging is an option. Dissecting it to be sure it doesn’t have any gills is essential (there are gilled poisonous mushrooms that start out looking somewhat like puffballs); as with all fungi that you’re thinking of ingesting, it’s best to have an expert along to identify it.

    do puffballs start underground? I have found small, more oval white fungi as I dig on the surface.
