base scanty, compact, of small cells. Gleba olive then umber ; when the 

 plant first deliquesces the gleba is bright yellow. Capiiiitium of deeply 

 colored threads. Spores small, 4 mic. globose, smooth. 



REFERENCES : This is the on.y common form of polymorphum that occurs 

 in the United States. It is included in all the American papers as Lycoperdon 

 coloratum (a synonym for the European plant) and in Morgan's papers also as 

 Lycoperdon cepaeforme.

LYCOPERDOX PUSILLUM* (Plates 53 and 65). Little glo- 

 bose specimens, rarely a cm. in diameter, which have all the characters 

 of the preceding species, excepting they have no sterile bases, we call 

 Lycoperdon pusillum. If we can note a sterile base, however slight, 

 we put the plant with cepaeforme and if we cannot note a sterile base 

 we call it pusillum. The distinction is too much like splitting hairs, 

 and we suspect that different plants of the same collection may be 

 referred to both species. In Europe, Lycoperdon pusillum seems more 

 distinct with a ripe gleba color, clear brown. In American specimens 

 the color is more of an olive tint and we think the typical European 

 plant does not occur with us.

LYCOPERDON PSEUDOPUSILLUM.* Specimens otherwise 

 Lycoperdon pusillum have soores which under a high power and best 

 objectives are slightly rough. These are called. Lycoperdon pseudo- 

 pusillum, but it is another case of cutting the cloth too fine.
