CHLOROMYXUM THYMALLI Lebzelter 



1912 Chloromyxum thymalli Lebzelter 1912 : 295-296 

 Habitat: Gall-bladder of Thymallus thymallus L.; Vienna? 

 Vegetative form: Irregular form, 32) to 35)u long in average. Endoplasm 



contains fat globules which stain brown with carmine. Trophozoites 

 attached to the epithelium. In average, 6 spores formed in each individual. 

 Intracellular stage in the epithelial cell is supposed. Polysporous. 



Spore: Spherical. Shell structure similar to C. protei, but ridges are 

 more developed and exhibit somewhat wavy courses. Polar capsules of 

 equal size. Dimensions: 9 to 9.5/1 in diameter, polar capsules 3^. 



CHLOROMYXUM KOI Fujita 

 [Fig 135] 



1913 Chloromyxum koi Fujita 1913 : 257-259 



Habitat: Gall-bladder of Cyprinus carpio L.; Sapporo (Nippon). 



Vegetative form: Spherical, with greatest diameter up to 50m, contain- 

 ing 1 to 3 spores. Each spore is situated in a clear space surrounded by a 

 membranous envelope (sporoblast?), around which there is some finely 

 granular matter (endoplasm?). 



Spore: Spherical, exhibiting a somewhat angular contour at the ante- 

 rior end. Shell thick and has well marked ridges on the surface, i.e., 4 to 5 

 circular ridges and on both sides of these ridges, two more ridges each bent 

 in a loop-like manner, so that the outline of spore in cross section, is very 

 much like of a toothed wheel with nearly equidistant teeth, 16 to 18 in 

 number. Four polar capsules, two slightly larger than the other two. 

 Dimensions: length 16/i, breadth 10/i, length of polar capsule 4/i, length of 

 polar filament 64/i. 



CHLOROMYXUM MAGNUM Awerinzew 



[Figs. 136 to 138] 



1913 Chloromyxum magnum Awerinzew 1913 : 155-156 



Habitat: Gall-bladder of Acanthias blainvillei;* Algoa Bay, East Lon- 

 don, Liideritzbucht (Africa). 



Vegetative form: Ameboid. Body yellowish by the presence of large 

 yellowish granules in endoplasm. Often round or rosary form. Pseudo- 

 podia sometimes absent, so that the trophozoites move like Amoeba Umax 

 with a cluster of small, hairy pseudopodia at the posterior end. In larger 

 form, small round pseudopodia, composed of homogeneous ectoplasm, are 

 formed. Plasmotomy by budding, was often observed. Usually polyspor- 

 ous, rarely monosporous. 



Spore: Elongated spherical form. Four polar capsules at the narrow, 

 anterior end. Sporoplasm with two nuclei. Dimensions: length 40 to 

 A2>n, breadth 30 to 38ju, length of polar capsules 12 to 15/x. 



* Misprinted in Awerinzew's paper as hlainvilei.
