Round organisms, 1.0 to 1.5 microns in diameter, generally grouped in aggregates of ir-

 Myxococcus pelomyxae; M.L. adj. parapelomyxae (Myxococcus) pelomyxae-Vike. 



Morphologically almost indistinguishable from Myxococcus pelomyxae. On agar enriched 

 with an infusion of a ground suspension of Pelomyxa, there are some growth differences 

 between the two species.
