Not likely good ones. Microsporidia are intracellular parasites without
mitochondria. 18s rDNA put them on a long branch at the base of the
Eukaryotes, and their lack of mitochondria seemed to confirm that. I heard
a talk at IBC, though, that placed them on the basis of other genes firmly
in the Fung... uh, sorry, Eumycota. Thus making an unemended Protista
*poly*phyletic.
