It is very common all over the state. I have seen pastures in Shelby and Defiance counties dotted all over with this species. When the inside is white, they are very good and meaty. No puffball is poisonous, so far as is known, but if the inside has turned yellowish at all it is apt to be quite bitter. It will often be seen in pastures and open woods in the form of a cup, the upper portion having broken away and the wind having scooped out the purple spore-mass, leaving only the cup-shaped base. The specimens in Figure 457 are just beginning to crack open and to show purplish stains. They represent less than one-fourth of the natural size. They look very much like the smaller sized C. gigantea, but the purple spores and the subgleba at once distinguish the species. This species, found from July to October, is sometimes classed as Lycoperdon cyathiforme. The photograph was taken by Prof. Longyear.
