who do not give to spores the same privilege of slight variation as to any 

 other character. We think spore characters are of as much relative 

 value as any other character, arid no more.

LYCOPERDON PUSILLUM* (Plate 53, fig. 9, 10 and 11). 

 The distinction between Lycoperdon cepaeforme with very little 

 development of the sterile base and Lycoperdon pusillum with no sterile 

 base is so slight that specimens of the same collection even, may em- 

 barrass the systematise Still, the little form that occurs typically in 

 Europe of L. pusillum is unique. Rarely over a centimeter in diameter 

 it is perfectly globose, with a strong tap root and a furfuraceous cortex. 

 The gleba does not tend to olive so strongly as in other forms of poly- 

 morphum but is a clear brown. \Ye are unable to distinguish any- 

 marked difference in the spores as recently shown in a picture.

THE "SPADICEUM" SECTION. 



LYCOPERDON SPADICEUM (Plate 54). Plants usually 

 obovate with short stem-like sterile base of large cells. Color when 

 young yellowish, becoming light brown when fully ripe. Cortex of 

 minute nodular, granular or somewhat furfuraceous spines. Fre- 

 quently we note on the peridium little white granules that seem to be of 

 the nature of a lime deposit, (lleba at first olive, finally brown. Capilli- 

 tium colored. Spores small. 4 mic. smooth. 



We accept this name on the interpretation given by Dr. Hollos. 

 Persoon left no specimen, and all that can be said is that the plant 

 does not disagree with his scanty and rather vague description. The 

 plant agrees with Lycoperdon polymorphum in everything excepting 

 that it has large cells in the sterile base. In Australia there are inter- 

 mediate forms connecting, the two species.
