BADHAMIA 39 



the stipes constitute a very prominent feature in every gathering in 

 our collection. Sometimes these are more or less coalescent, especially 

 toward the base, where they are apt to be also wrinkled or longitudi- 

 nally striate; in other specimens the stipes are well differentiated, long, 

 terete, with little or no hypothallus. 



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

 South Carolina. Berkeley thought it a didymium and called it 

 D. curtisii, Massee regarded it as a craterium. 



Badhamia dictyospora Rost., Mon. App. 4, 1876 {Craterium dictyosper- 

 mum Massee, Mon. 270, 1892), with obovoid sporangia, and spores 

 coarsely warted or subreticulate, is reduced to varietal rank by Lister. 



Var. globosa Lister, Jour. Bot. 42 : 130, 1904, is described as having 

 subglobose, stipitate sporangia, dark columella and strongly reticulate 

 spores. A collection from North Wales, so determined by Dr. Elliott, 

 has as many obovate as globose sporangia, but the large, dark spores 

 are beautifully reticulate. 



Abundant in the forested regions of North America, especially in 

 the Mississippi valley. Also western Europe, Poland and Rumania. 

 The varieties not reported from North America, but recorded from 

 Europe, Japan, South Africa, Hawaii. 



21. Badhamia subaquila Macbr. 



N. A. Slime-Moulds 64. 1899. 



Sporangia closely gregarious or crowded, globose or subglobose, 

 sessile, brown; peridium a thin but persistent brown membrane, rup- 

 turing above irregularly and remaining as a cup after spore dispersal; 

 hypothallus none; capillitium strongly developed, thoroughly cal- 

 careous, the meshes large, the nodular thickenings broad, white; 

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

 warted, large, 15-18 fx. 



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

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

 cites the species (Bull. Tor. Bot. Club, 24 : 67) as B. verna (Somm.) 

 Rost. But the specimens certainly do not conform to the description 

 of B. verna. The wall corresponds with that of B. rubiginosa; but the 

 spores are much larger, and the capillitial structure very different. 



Miss Lister regards this as a form of B. rubiginosa. So far, the 

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

 certain one day to send added information. 



Maine. Rare.
