BADHAMIA 69 



B. ntricularis ; and the sporangia sessile, or with strand-like 

 stipes, distinguish it from B. papaveracea. 



Not uncommon from New England west to Iowa ; rare west 

 of the Mississippi River.

1873. Badhamia papaveracea Berk, and Rav., Grev., II., p. 66. 

 1894. Badhamia hyalina var. papaveracea Lister, Mycetozoa, p. 30. 



Sporangia closely gregarious, globose, large stipitate, irides- 

 cent gray; the peridium thin, translucent, and containing but 

 little calcareous deposits, 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 ad- 

 herent as in B. capsnlifcra, marked in much the same way, and 

 about the same size, 10-12.5 ^. 



Distinguished by its short dark stipe and adherent spores. 



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

 South Carolina, Wisconsin, Iowa.

1855. Physarum macrocarp'on Cesati, Flora, p. 271. 

 1875. Badhamia macrocarpa (Ces.) Rost., Mon., p. 143. 



Sporangia scattered or closely aggregate, crowded globose 

 or sub-globose, generally sessile, rugulose, white ; the peridium 

 membranous, white above, below yellowish or brown ; capillitium 

 not abundant, thoroughly calcareous, the nodes broad, conspicu- 

 ous, the connecting tubules rigid ; columella none ; hypothallus 

 scant or none ; spore-mass black, spores non-adherent, by trans- 

 mitted light bright clear brown, thickly spinulose all over, large, 

 spherical, 12-15 /^. 



Closely resembles externally B. fanicea, but is easily distin- 

 guished by larger and remarkably spinulose spores, in this 

 particular unrivalled in the entire genus. European authors
