Scanning electron microscopic revision of common species of the genus Chloromyxum (Myxozoa: Myxosporea) infecting European freshwater fishes
Seven species of the genus Chloromyxum Mingazzini, 1890 infecting freshwater fishes in the Czech Republic arc redescribed using scanning electron microscopic (SEM) observation of surface structures of their spores, and one is described as a new species. The pattern of ridges on the spore surface is...

Seven species of the genus Chloromyxum Mingazzini, 1890 infecting freshwater fishes in the Czech Republic arc redescribed using scanning electron microscopic (SEM) observation of surface structures of their spores, and one is described as a new species.

However, the features are clearly visible with SEM. In fact, this method becomes a prerequisite for any well based description of Chloromyxum species.
