Plate 15. Figure 7. X I 



Peridium globose or subglobose, sessile or nearly so, white, 1-4 

 cm. in diameter; surface densely covered with stellate spines or 

 pyramidal warts that fall away at maturity, exposing the 

 glabrous or minutely velvety, buff-colored inner peridium; capil- 

 litium and spores dingy olivaceous, columella present; spores 

 globose, sessile, finely granular, about 4/x in diameter. 



This species is very common during summer and autumn along 

 paths and in dry pastures, usually occurring in great numbers 

 and reminding one of a collection of white marbles of various 

 sizes scattered upon the ground. Upon closer observation the 

 characteristic coating of spines appears, which breaks into flakes 

 and falls away at maturity, as is well shown in the figure.
