An extinct order of bryozoans in the class Stenolaemata. Cystoporates tend to have robust colonies composed of relatively simple, long, slender, and tubular zooecia (with thin, somewhat porous calcareous walls), separated by blisterlike vesicles (cystopores) stacked upon one another. Their colonies display a very gradual transition between comparatively indistinct endozone and exozone regions.
