306 United States Species of Lycoperdon. 



attached to each other so that they come off at maturity 

 in flakes or patches. When the denuded surface of the 

 peridium is velvety it is usually of a darker color than 

 when smooth, being subcinnamon, reddish-brown or dark- 

 brown. 



Lycopeedon pedicellatum Pk. 

 Pedicel-sporecl PufF-ball. 



Peridium in diameter, globose or depressed- 



globose, sessile or narrowed below into a stem-like base, 

 whitish or cinereous, becoming dingy or smoky-brown 

 with age, echinate with rather dense spines which are 

 either straight curved or stellately united and which at 

 length fall off and leave impressions or obscure reticula- 

 tions on the surface ; capillitium and spores greenish- 

 3^ellow, then dingy-olive, columella present; spores smooth, 

 pedicellate, 00016^-00018^ in diameter, the pedicel three 

 to five times as long. 



Ground and decaying wood in woods and bushy places. 

 Groghan, Genter, Brewerton and Gatskill Mountains. 

 Oneida, Warne. Autumn. 



The pedicellate spores constitute the peculiar feature of 

 this species. It is one which suggests the name and 

 which enables the species to be easily distinguished from 

 all its allies. The spore is terminally and persistently 

 attached to the pedicel as in some species of Bovista. 

 The plant is sometimes sessile, but usually it is narrowed 

 below into a stem-like base. In the immature state it has 

 a rough, shaggy appearance but the spines shrivel with 

 age so that it appears less . rough when old. The pitted 

 surface of the denuded peridium affords a mark of distinc- 

 tion from the next species. 



L. pulcherrimurn B. & G. is evidently the same species. 

 The name here adopted has priority of publication. 



Lycoperdon echinatum Pers. 



Echinate Puff-ball. 



Peridium IC-IS'' broad, subglobose, generally nar- 

 rowed below into a short stem-like base, whitish brownish
