 particles and migrating to new site; when transferred to fresh dish of 

 water, "spore-like" bodies are dispersed; fresh water among decaying 

 leaves. Nauss (1949) points out its affinity to Proteomyxa, Myceto-

R. filosa N. (Fig. 178, e). On moist blotting paper the central mass 

 is an elevated body, but in water it spreads into a broad sheet, 4-6 

 mm. in diameter; pseudopodia may be up to 10 times the diameter 

 of the central white mass; encyst ment occurs when subjected to
