The Schizo-saccharomycetes, again, form a group which 
suggest obvious relationships to the yeasts, while Thaxter’s 
Myxobacteriaceae point to alliances with the Myxomycetes. 
All things considered, therefore, I think we should be 
prepared to accept that the morphological relationships of 
the minute organisms grouped together as Schizomycetes are 
neither few nor simple, and that their phylogeny is probably 
not even comparable with a complex tree-form, but is multiple 
in origin.
