Fig. 12. Brefeldia maxima. Nuclei with nucleoli of plasmodium stained with 
magenta, x 1200. 
Fig. 13. Badhamia utricularis. Young spores showing amoeboid movement, 
the spore a changing its form to a"' in the course of a few minutes, x 565. 
Figs. 14 and 15. Starch grains swollen in warm water, drawn from the side of 
glass box in which Badhamia utricularis was spreading. The grains in Fig. 15

in size as by letters, taken at intervals of about a quarter of an hour, x 250. 
Fig. 17. Mycelium growing on side of glass box. a edge of advancing 
plasmodium of Badhamia utricularis when it first reached the mycelium, b line 
reached by plasmodium before it retreated, c, d threads of mycelium, which were 
dissolved by plasmodium between the lines a and b. x 66. 
Fig. 18. c' the thread c drawn half an hour after the plasmodium had retreated, 
showing the extremity breaking into bead-like fragments from action of plasmodium. 
c" the same some hours after, showing extent of injury beyond the point reached 
by plasmodium. e fragments of mycelium, showing all that remained of the threads 
c and d between the lines a and b. x 250.
