1895 Chloromyxum diploxys 



Habitat: Abdominal cavity of Tortrix viridana L. (imago); 



Vegetative form: Trophozoites form spherical cysts, 230 to 400jli 

 in diameter. Cyst membrane rather thick. Protoplasm containing 

 brownish granules, and fat-hke globules (red with iodine). 



Spore: Elliptic or slightly flattened. Sutural line straight, forming a 

 ridge. Two polar capsules at each end. 



CHLOROMYXUM PROTEI Joseph 



1905 Chloromyxmn protei Joseph 1905 : 450-451 

 1907 Chloromyxum protei Joseph 1907 : 398-412 



Habitat: Renal tubules of kidney of Proteus anguineus L.; Vienna. 



Vegetative form: Generally rounded or sausage form. No clear 

 differentiation between ectoplasm and endoplasm. Movements slow. 

 Probable occurrence of plasmotomy by budding and division. Size: 

 40 to 45/1 by 28 to 40/x. 



Spore: Spherical. Shell finely striated parallel to the sutural line. 

 Four polar capsules each with an independent opening. Dimensions: 

 10 to 13/x in diameter, polar capsules 4 to 6/x long. The polar filament 

 appears to be rather short. 



CHLOROMYXUM TRUTTAE Leger 

 [Fig.126] 



1906 Chloromyxum truttae Leger 1906 : 267-270 

 Habitat: Gall-bladder and gall-duct of Trutta fario L.; Dauphine. 

 Vegetative form: Ameboid form. Elongated. Form resembles an 



Amoeba Umax of about AOfx in length. Roundish or irregularly contoured, 

 with small pseudopodia. Ovoidal or spherical, 25 to 40/i in diameter 

 without any visible pseudopodia (resting state). Body colorless, clear and 

 hyaline. Very active movements which last for several hours after the 

 death of the host. Broad and obtuse pseudopodia well developed at the 

 anterior end of the body. Endoplasm alveolar, contains variable numbers 

 of nuclei, which are seen in vivo, refractive bodies and chromatic granules. 

 Monosporous(?) and polysporous. 



Spore: Spherical. Four polar capsules of different size. Shell- valves 

 marked with parallel ridges. Dimensions: 8 to 9ju in diameter.
