A GLOBOSE FORM OF LYCOPERDON 

 GEMMATUM. 



Mr. E. B. Sterling, Trenton, N. J., has at various times sent us 

 some very interesting plants. He has a son at Dawson, Yukon, who 

 has collected a number of "puff balls" for his father. 

 Among these we find a globose form of Lycoperdon 

 gemmatum, Fig. 150, and a number of the usual shape. 

 Lycoperdon gemmatum is the most common species 

 both in Europe and America, and it generally has a 

 sterile base, well developed. That this species, which 

 Fig. 150. - n ^g United States and Europe always has a stem- 



like base, should in the extreme north become globose with a very 

 slight development of the sterile portion, is of interest as showing the 

 influence that climate and conditions have on plants. This form has 

 the same relation to the normal form of Lycoperdon gemmatum as the 

 United States form Lycoperdon cepasforme has to the type form, 

 Lycoperdon polymorphum of Europe.
