Polyangium (= Myxobadcr, Cystobacler). — The rods form large 

 rounded cysts one or more of which are free inside a gelatinous stalked 

 matrix. 



Myxococcus. — Slender rods which swarm together, after a vegetative 

 phase, to form well-defined, more or less sessile or stalked encysted 

 masses of coccus-like spores.
