Gregarious or cespitose; peridium 6-12 lines broad, glolbose or subglobose, sessile, the surface covered with small close subpyramidal granular or spiny warts which in the mature plant fall, leaving minute pits in the surface of the inner peridium, pinkish brown; capillitium and spores olivaceous; spores globose, .00016-.0002 of an inch broad.

The pinkish puffball is found in woods, growing on decaying wood, stumps, and prostrate trunks of trees and may be found from July to September. It is peculiar to this country. It rarely exceeds one inch in diameter and except when growing in dense clusters it is quite regularly globose and either sessile or with a very short sterile base. It is easily distinguished by its dull pinkish brown color and sessile peridium while immature, and by the grayish minutely pitted inner peridium of the mature or old plants. It is well to remove the exterior peridium before cooking. The texture is a little tough and the flesh is not highly flavored, but when fried in butter it is agreeable to the taste, digestible and harmless. No puffball should be eaten after its flesh has lost its white color.
