,6 NATURAL HISTORY BULLETIN. 



lar, with a plicate base and fibrous mycelium; outer peridium 

 white, cinereous or brownish consisting of soft slender spines 

 or hairs, which at length fall away leaving the smooth, shining 

 brownish-purple surface of the the inner peridium; sub-gleba, 

 broad about one-third of the peridium; mass of spores and 

 capillitium olivaceous then purplish-brown; capillitial threads 

 about equal to the spores with long, acuminate branches; 

 spores globose, spinescent, pedicellate, 5-7 /'• 



Rare. Found occasionally in woods or sandy pastures. 



The warts of the outer peridium are something like those of 

 L. gcmmatum, and from their color, immature specimens 

 might possiblv be mistaken for that species. The present 

 species is, however, solitary and sessile and the peridial warts 

 are nearly uniform, all of one size, generally with a reddish 

 tinge when the plant grows in the shade. 



3. Lycoperdon asterospermum Dur. tf- Mont. 



Sporocarp obovoid or short-turbinate, 1-1% inches in diam- 

 eter, short and pointed below with a fibrous rooting mycelium; 

 outer peridium a thin coat of closely set minute spinult^s pre- 

 senting a granular appearance to the naked eye, yellowish or 

 brownish above, paler below, at length deciduous; inner 

 peridium dull yellow, smooth, shining, very thin but papery 

 and persistent; sub-gleba obconic, about one-third the height 

 of the peridium; gleba at maturity, brownish-purple, the capil- 

 litial threads about equalling the spores, the branches, long 

 acuminate, spores globose, warted, 5-6 ». 



Not rare on the ground in open woods and orchards. Dis- 

 tinguished from the preceding by its much more delicate outer 

 peridium, by the thin, shining, persistent inner peridium and the 

 bright brown capillitium, persisting after the spores are blown 

 away. 



4. Lycoperdon elegans Morgan. 



Sporocarp large, 1^-3 inches in diameter, depressed glo- 

 bose, plicate beneath, and sometimes with narrow unboniform 

 base, which is continuous with the thick root; outer peridium 

 at first flocculose, white or yellowish, drying up into a dense
