18 Mycetozoa of North America 



2. Badhamia papaveracea Berk. & Rav. ; Berk. Grevillea 2: 66. 



1873. (N. Y. B. G. no. 6685, type material.) 



Plasmodium? Sporangia gregarious, subglobose or obovoid, 

 stalked, smooth or rugose, grayish or bluish, 0.5 to 1 mm. diam.; 

 sporangial wall usually with scanty deposits of lime. Stalk firm, 

 dark, nearly black. Capillitium of slender strands as in B. cap- 

 sulifera. Spores purplish brown, in firm clusters of 6 to 10, more 

 strongly warted on the outer third, 10-13 m diam. 



Type locality: South Carolina. 



Habitat: On dead bark; not common. 



Distribution: *Alabama, *California, Connecticut, *Iowa, 

 *Maine, New Jersey, New York, *Ohio, Pennsylvania, South 

 Carolina, *Wisconsin. 



Illustration: Lister, Mycetozoa ed. 3. pi. 3, figs, d, e. 



This species is close to B. capsulifera, but distinguished by the 

 firm stalks, which are darker, longer, and thinner. The spores are 

 usually paler, and the clusters smaller than those of B. capsulifera. 

 Sessile and intermediate forms mentioned by Lister, should be 

 placed with B. capsulifera, as there is no way of separating them 

 satisfactorily. 



3. Badhamia populina A. & G. Lister, Jour. Bot. 42: 129. 1904. 



(N. Y. B. G. no. 10730, authentic material.) 



Plasmodium white or cream-white (Lister). Sporangia sessile 

 and heaped, or solitary on short, yellowish, membranous stalks, 

 subglobose or obovoid, 1.5 mm. diam., smooth, white, rarely 

 pinkish; sporangial wall with dense deposits of lime-granules, 

 sometimes partly veined or ribbed. Capillitium a coarse network 

 of broad strands charged with white lime-granules. Spores 10- 

 12 ix diam., in clusters of 16 to 20 or more, purplish brown, min- 

 utely warted, somewhat stronger on one side, and usually showing 

 narrow lines or ridges on many of the spores. 



Type locality: England. 



Habitat: On dead wood, usually poplar. 



Distribution: Colorado, ^Montana, Oregon, *Washington. 



Illustration: Lister, Mycetozoa ed. 3. pi. 2. 



This species, so far, has been found only in the western moun- 

 tains. It is readily distinguished from B. capsulifera by the 

 larger, more robust sporangia, superimposed in clusters, and the 

 dense deposits of lime in the sporangial walls. The capillitium is 

 coarser, and the spores often show lines and ridges.
