Macrotaxonomy of the Microsporidia phylum

Different classification of the phylum Microsporidia (Sprague, 1977; Weiser, 1977; Issi, 1986; Sprague, Becnel, Hazard, 1992) are briefly discussed. New taxa (families Glugoididae, Flabelliformidae, Neopereziidae, Rectosporidae and superfamilies Encephalitozoonoidea, Cylindrosporoidea) are proposed in the new classification of Microsoridia.
