80 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA 



633. On stump of dead beech tree in Battle's Park, October 24, 1912. 



917. Scattered in large numbers over several yards on earth and in and by the brick drain and in grass 

 just east of the Alumni Building, October IS, 1913. This colony of plants was interesting in 

 being apparently unconnected with wood. The mycelium could be traced as white strands for 

 some distance into the rather poor earth and then was dissipated into invisible fibers. All 

 characters exactly as in plants on wood. The plants were fully grown a month before the 

 apical pores appeared. 

 1046. On exposed dead root in Bowlin's Creek swamp, December 6, 1913.

Lycoperdon subincarnatum Peck 



Plates 51, 57 and 113 



Plants small, about 1-2.5 cm. thick, depressed-globose, almost or quite sessile, 

 growing on logs or stumps and attached by byssoid strands; color when young reddish 

 brown, at maturity becoming dark brown or dull leather brown; covered with minute, 

 separate, brown warts or with little pointed spines in groups with united tips, their 

 bases connected by a smooth thin tissue of the same color; after full maturity these 

 warts or spines and tissue slowly wearing away and leaving exposed the paler brown, 

 dull inner peridium, which is very firm and tough and is marked all over with small pits 

 outlined by acute ridges, appearing under a lens exactly like a thimble. This re- 

 ticulated surface is assumed after maturity, in any case, whether the outer peridium 

 falls away or not and is obvious through the outer peridium which accommodates itself 

 to it. Subgleba scanty or practically absent, composed of small pale chambers. 

 Gleba peculiar in the distinctly radiating tramal plates which, before maturity, give 

 a section very much the appearance of a Geaster; color at maturity grayish purple. 

 In some specimens there is a very distinct columella, thus increasing the resemblance 

 to Geaster. 



Spores (of No. 3171a) dull brown, spherical, when dry appearing distinctly 

 warted, when in water appearing spiny under high power, 3.8-5/i thick, counting the 

 spines. Capillitium of long, simple or sparingly branched, very pale threads (much 

 paler than the spores) up to 6.5ju thick, the walls irregularly thickened in places, some- 

 times closing the lumen. 



This species is a strongly marked one and is easily distinguished by the small deep 

 pits, growth on wood, sessile habit and peculiar capillitium. In most of our collections
