 Plasmodium chrome-yellow. Sporangia globose or pyriform, sessile 

 or stipitate, 0*7 to 1"5 mm. diam., greyish-white, pure white after 

 dispersion of the spores; sporangium-wall hyaline, with lime- 

 granules sparsely distributed. Stalk usually short or wanting,

 lime-granules evenly but not densely distributed throughout. 

 Spores dark purple-brown, adhering in clusters of 8 to 20, coarsely 

 warted on the outer third, minutely spinulose on the rest of the
