very delicate above, but persists below as a cup-shaped base 

 after the spore-mass has entirely disappeared. The capillitium 

 is a beautiful yellow, strongly contrasted with the rich black 

 mass of spores. The curiously compressed sporangia are 

 narrowly sessile, but not stipitate; have no hypothallus. July. 

 Decorah. Mr. Hohvay. 



BAD KAMI A, Berkeley. 



Sporangia simple. Peridial wall simple, thin, breaking 

 irregularly. Capillitium formed of abundant, richly anasto- 

 mosing tubules, filled throughout their entire length with cal- 

 careous granules; the nodes feebl}^ represented. 



64. Badhamia papaveracea, Berkeley and Ravenel. Plate 



X, Figs. 6, 6a and 6b. 



Sporangia globose, short stipitate, crowded, white, rugu- 

 lose. Capillitium reticulate, white. Spores black, .010, fre- 

 quently obovate, granulate above, in clusters of about seven. 



This beautiful species is rare. Small plasmodia occur on 

 fallen oak in the deeper woods. The thin blue-white, rugu- 

 lose peridia are exceedingly delicate, and quite characteristic. 

 The spores are delicately warted, and tend to aggregate in 

 small clusters ; occasionally a single one appears, much larger, 

 .012-.014. 



65. Badhamia rubigixosa, ChcvalUer. Plate X, Figs, i, 



la and \b. 



Sporangia globose-turbinate, stipitate. Stipe slender, twice 

 the sporangia, rusty-brown, smooth. Peridium smooth, some- 

 what shining, purplish-brown, opening by a somewhat regular 

 fissure as by a lid. Capillitium well developed, white. Colu- 

 mella more or less distinct, formed of the intruding stipe. 

 Spores delicately warted, violaceous, .012-.015.
