Haplosporidia - Morphology Scanning Electron Microscopy. The phylum Haplosporidia is described as being a group of parasitic protists that form uni-nucleated spores without polar capsules or polar filaments; the sporoplasm is contained by a spore wall that has an orifice at one pole (Perkins, 1990, 1996). There are three genera-
Minchinia Labbй 1896,
Haplosporidium Caullery and Mesnil 1899, and
Urosporidium Caullery and Mesnil 1905. [eng]
HAPLOSPORIDIA definition An order of sporozoans, now placed in the protozoan phylum Ascetospora, class Stellatosporea, that reproduce asexually by schizogony and produce spores but no flagella, though pseudopodia may be present.
