Scanning electron micrographs show a smoothly fibrous structure of the cyst wall of the trematode Posthodiplostomum minimum, whereas the enclosed metacercaria posses a porous and papillate surface with occasional spines. Numerous excretory concretions fill the body of the metacercaria. The concretions appear layered from a central core and show an abundance of calcium, and, in some cases, magnesium. © 1976.
