The vegetative form divides by multiple or binary fission 

 into uninucleate rounded bodies or sporonts, each of which 

 gives rise to a single ovoid or pyriform spore, which is not 

 enclosed in a capsule.

Spores elliptical or oval, with sharp and distinct boundary 

 wall. They stain a rather pale, washed-out blue, with a central 

 dot which may be of a deeper blue or red colour, and both 

 kinds may occur in the same intracellular group. Planonts 

 irregular in shape. Cytoplasm stains a bright shade of slate-
