MITOSPORIDIUM [Microsporidia] described as new genus under zoological code by Haag KL et al. PNAS 111: 15480–15485. 2014
Mitosporidium daphniae species authors not designated. Haag KL et al. PNAS 111: 15480–15485. 2014. Described under zoological code but lacked designation of type; therefore not validly published. Of interest is that Microsporidia are excluded from the “International Code of Nomenclature for algae, fungi, and plants,” yet the Haag et al publication presents additional evidence for the relationship of the Microsporidia with the Chytridiomycota and other fungi.
