Badhamia panicea, Rost. (figs. 74 76). 



Sporangia gregarious on a thin hypothallus, sessile on a 

 broad or narrow base, globose or irregularly angular from mutual 

 pressure, wall thin, often iridescent, studded all over with innate, 

 detached, irregular patches of lime, the whole with a grey tint ; 

 capillitium very dense, snow-white, knots large, branched, con- 

 nected by thick bands, every part densely filled with granules 

 of lime; spores free, or with an indication of being originally

Plasmodium white. Sporangia up to 1 mm. diameter, gener- 

 ally crowded and forming dense pale grey patches. Closely re- 

 sembling superficially Badhamia macrocarpa, but distinguished 

 by the coarser capillitium having every part crowded with lime, 

 the much smaller warts on the epispore, and the absence of 

 rugulose veins on the sporangial wall.
