36 THE NORTH AMERICAN SLIME-MOULDS 



rugulose, and more or less calcareous-scaly ; the stipe when present 

 erect or sometimes nodding, black or brownish black; hypothallus 

 scanty; columella none; capillitium not abundant, white, the nodes 

 somewhat expanded ; spores globose, minutely roughened, violet- 

 brown, large, 16-17 yu. 



Chiefly on moss, the pale ashen sporangia generally very small, 

 mounted on the tips of the leaves, sometimes sessile, sometimes with a 

 distinct black stipe in which case the peridium is distinctly umbilicate. 

 Specimens from Kansas referred here have the stipe pale, rugose, 

 long, about twice the sporangium; habitat bark. 



Rare. New York, Ohio, Kansas; more recently reported from 

 Scotland and Japan. 



There is nothing new to be added here ; nor appears any other 

 place to which such material as we have may be referred. New 

 collections no doubt will one day appear, when the identity may, let 

 us hope, be made secure. 



Meantime we have a form closely related which may be entered as 



Badhamia iowensis Macbr. n. s. 



Sporangia gregarious or loosely scattered, depressed globose, .4-.6 

 mm. in diameter, stipitate, grey, flecked by rather prominent but 

 small rounded calcareous scales: the stipe short, half the diameter of 

 the sporangium, black or very dark brown, without hypothallus but 

 widening above into a shallow expanded base for the sporangia; 

 columella none: capillitium dull yellow, sometimes white, strongly 

 calcareous, physaroid, heavy; spores free, dark brown in mass, pale 

 violet by transmitted light, minutely verruculose, the tiny warts in 

 some areas more densely placed, producing evident shadowy spots, 

 10-11 /x. 



This interesting little species occurs on the lower surface of fallen 

 logs, blocks, etc., in colonies of considerable extent, hundreds of 

 sporangia in a place. The capillitium is comparable to that of B. 

 decipiens or B. panicea; it is physaroid to the extent that an occasional 

 filament may be found non-calcic, and not typically badhamioid as in 

 B. papaveracea, B. macrocarpa. The sporangial base persists, dark 

 brown, bearing traces of the clumsy capillitium, but no columella
