44 THE NORTH AMERICAN SLIME-MOULDS 



to be mistaken for those of any other species; the stipes constitute a 

 very prominent feature in every gathering I have seen. Sometimes 

 these are more or less coalescent, especially toward the base, where 

 they are apt to be also wrinkled or longitudinally striate; in other 

 specimens the stipes are well differentiated, long, terete, with little or 

 no hypothallus. 



Badhamia curtisii (Berk.) Rost. is according to Lister (Mon., 

 p. 35) a sessile phase of this species. The only specimens known are 

 in the herbarium of Berkeley, now at Kew. The species is based upon 

 a gathering from S. Carolina. Berkeley thought it a didymium, called 

 it D. curtisii. 



Reported from western Europe; the typical form abundant in 

 the forested regions of eastern N. America, especially in the Missis- 

 sippi valley.

 1899. Badhamia suhaquila Macbr., N. A. S., p. 64. 



Sporangia closely gregarious or crowded, globose or subglobose, 

 sessile, brown, the peridium a thin but persistent brown membrane, 

 rupturing above irregularly and remaining as a cup after spore 

 dispersal ; hypothallus none ; capillitium strongly developed, thorough- 

 ly calcareous, the meshes large, the nodular thickenings broad, white ; 

 spores globose, in mass black, by transmitted light brown, very rough- 

 warted, large, 15-18 fi. 



The variety is founded on material sent from Maine by the late 

 Mr. F. L. Harvey. Professor Harvey, upon the authority of Mr. 

 Morgan of Ohio, quotes the species. Bull. Tor. Bot. Club, 24, 67, as 

 B. verna (Somm.) Rost. But the specimens certainly do not conform 

 to description of B. verna. Here the wall corresponds with what 

 is seen in B. rubiginosa; but the spores are much larger, and the 

 capillitial structure very different. 



Miss Lister regards this a form of No. 16. So far, the original 

 gathering represents the species; but the woods of Maine are certain 

 one day to send added information. 



Rare. On mossy logs, Maine.
