BADHAMIA 39 



B. foliicola as recognized here is hardly more than a smaller, short- 

 stemmed form of this ; see species next following. 



Not rare in the eastern United States and Canada; Iowa. Seems 

 to take the place of B. capsulifera of Europe.

"Plasmodium orange." Sporangia smaller, about .5-6 mm., 

 globose or ellipsoidal, iridescent-gray, stipitate or sessile, the perid- 

 ium thin, rugulose, sparingly calcareous, when empty white; the 

 stipe when present short but yellowish, of the flaccid sort ; capillitium 

 badhamioid ; spores free, delicately spinulescent, dusky-violaceous, 

 about 12-13 IX. 



This has been so far collected but once, on the shores of Lake 

 Okoboji. It was developed, no doubt, on the natural debris of a 

 bur-oak prairie border, and went to fruit on the leaves, stems, and 

 fruiting spikes of a species of Setaria. It may prove to be different 

 from the B. foliicola of Europe; future collections and study must 

 reveal that. Meantime it seems wise to refer it here. 



The color of the Plasmodium is quoted from Miss Lister; a fact 

 of some importance only when constant and confirmed by other 

 criteria.

Sporangia clustered, spherical or ovoid, large, sessile or mounted on 

 long, thin, strand-like stalks, blue-gray, violet-iridescent or cinereous, 

 smooth or more often rugulose; the stipes when present poorly differ- 

 entiated, as if thread-like filaments and strips of the Plasmodium, often 

 branched and always reclining or even prostrate; hypothallus none;
