Sporangia gregarious, globose, large, stipitate, iridescent-gray; the 

 peridium thin, translucent, and containing but little calcareous de- 

 posits, smooth or slightly rugulose; stipe very short, but generally 

 distinct, black or very dark brown; hypothallus none; capillitium 

 a network of large meshes with expanded nodes, prominent, white, 

 persistent after the spores have been blown away; spore-mass deep 

 brown ; spores adherent as in B. capsulifera, marked in much the 

 same way, and about the same size, 10-12.5 fx. 



Distinguished by its short, dark, stipe and adherent spores. 



Not common. New England, Pennsylvania, Ohio, Maryland,

Sporangia globose, sub-globose, or obconical, sessile, gregarious or 

 more or less clustered, supported by a thin, continuous, transparent 

 hypothallus; the peridium smooth pale, lilac-brown without, white 

 within ; stipe none, although some sporangia have a narrowed base ; 

 columella none, the pseudo-columella formed by a more densely ag- 

 gregated capillitium near the base; capillitium dense, white, strongly
