LYCOPERDACEAE 81 



the peridium is much more rigid and leathery than in most puffballs, but in our No. 

 3171a from Chapel Hill it is more pliable, though still thick and leathery. In this lot 

 too, the outer peridium is more scurfy than warty and has not become at all worn off 

 though the plants are old, and the spores have slightly longer spines. The surface has, 

 however, assumed the pitted appearance in about the same fashion as other lots. All 

 other characters are the same.

We copy the following from Morgan's original description (Journ. Cin. Soc. Nat. 

 Hist. 14: 16. 1891): 



"Peridium turbinate, globose or depressed-globose above, contracted below into a 

 stem-like base, with a filamentous and fibrous mycelium. Cortex a thin white or yel- 

 lowish coat of minute spinules with intermingled granules, which are coarser towards 

 the apex; these wither or shrivel with age and are mostly persistent on the smooth 

 olive-brown, shining surface of the inner peridium. Subgleba occupying little more 

 than the stem-like base; mass of spores and capillitium greenish yellow, then brownish 

 olivaceous; spores minutely warted, 4-4.5^ in diameter. 



"Growing among mosses, especially Polytrichum, in old meadows and pastures. 

 New York, Peck. Peridium one-half to one and one-third inches in diameter and 1-3 

 inches in height. This is L. molle of Peck's U. S. Species of Lycoperdon." 



Peck calls attention to the resemblance of this plant in the immature state to 

 Cahalia data. The mature plant is easily distinguished from the latter by the apicaJ 

 mouth, and the average size is smaller.
