Haag et al., 2015

Mitosporidium is a genus of microsporidian parasites. The genus was erected in 2014 but, for nomenclatural reasons, the taxon was valid only in 2015.

In contrast to most members of the Microsporidia, species in Mitosporidium have retained ancestral features such as mitochondrial respiration. However, they have a spore stage with a polar tube which is a unique characteristic of the Microsporidia, and they are intracellular parasites.
