peiidium thin, 'becoming smooth, usually plicate below, stem 

 2-4 in. high, 1 in. thick, sometimes the whole fungus is much 

 larger than the above measurements. The stem is often 

 irregularly lacunose. 



Lyooperdon gemmatum. Bafsch. 



Subglobose, depressed, obtuse, with large, brown pointed 

 warts which fall away, leaving the surface smooth and 

 shining, dehiscing by a small apical opening ; sterile cellular 

 base prominent, passing downwards into a long, thick stem 

 tapering downwards ; mass of spores olivaceous-umber ; 

 capillitium dense, threads branched ; spores globose, minutely 

 warted, 4 /x. 



Lycoperdon gemmatum, Mass., Men. Gast., p. 70, f. 30. 



Among grass, ferns, &c., in woods. The present species 

 has been almost invariably confused with L. perlatum, from 

 which it is distinguished by the warted spores; 3-4 in. high, 

 1-2 in. across. Distinguished from L. saccatum by the 

 peridium not being plicate below and the smaller spores. 



* * Spores smooth. 



Lycoperdon pyriforme. Schoeff. (fig. 1, p. 28.) 



Pyriform or subglobose, rather umbonate ; peridium thin 

 and flaccid, covered with minute pointed warts, becoming 

 smooth, dehiscing by a small torn opening ; furnished with 

 numerous rooting white strands of mycelium at the base ; 

 threads of capillitium branched, springing from the cellular 

 base and persisting as a columella-like central mass ; mass 

 of spores olive, globose, smooth, about 4 p.. 



Lycoperdon pyriforme, Cke., Hdbk., n. 1089; Mass., Mou. 

 Gast., p. 71, f. 61. 



On rotten wood ; and on the ground attached to branches, 

 &c. Generally densely tufted and connected by numeroiis 

 white, branching roots ; from 1-3 in. high, typically pyriform 

 with a distinct umbo, sometimes subglobose. 



Var. excipuliforme, Desm. 



Peridium contracted abruptly into a slender, equal stem. 



Lyooperdon perlatmn. Pers. 



Subglobose with an elongated stem-like base or spherico- 

 depressed and nearly sessile, often plicate or lacunose below, 

 always umbonate, covered with stout, short spines, each
