122 ILLINOIS BIOLOGICAL MONOGRAPHS [360 



Spore: Large, elongated fusiform; ends less truncated than those of 

 the spore of Sphaeromyxa balbianii. As the spore becomes mature, the 

 ends assume more pointed shapes. Polar capsules two, one at each end. 

 Sporoplasm with two nuclei, fills the extracapsular cavity. Dimensions: 

 twice or three times larger than those of Sphaeromyxa balbianii Thelohan.

1910 Zschokkella hildae Auerbach 1910a : 240-254 



1912 Zschokkella hildae Auerbach 1912 : 40-41 



Habitat: Urinary bladder of Phycis blennioides Br., Gadus aeglefinis, 

 G. callarias L., G. viretis L.; Norway. 



Vegetative form: Trophozoites float in the bile or attach themselves 

 to the epithelial layer of the bladder. Youngest ameboid form about 

 4.5 to 6/Li. In floating form, pseudopodia more or less long, lobose, are 

 formed; while in the attached form those similar to the pseudopodia of 

 Myxidium bergense Auer. are developed. Plasmogamy occurs. Size 

 varies greatly according to the number of spores which are formed in each 

 individual. Monosporous (with or without the remnant of protoplasm), 

 disporous and polysporous (up to 4 spores). 



Spore: Semicircular in front view, with slightly and equally attenuated 

 ends. At each end, large spherical polar capsule is situated which opens 

 not at the extremity, but on the flat surface. Shell bivalve and thick. 

 Sutural line S-form. Sporoplasm with two nuclei. Dimensions: length 

 16 to 28.8fx, breadth 13 to ISjx, polar capsules 5.6 to 7.2/i in diameter, length 

 of polar filament 72)u (KOH). 



ZSCHOKKELLA NOVA Klokacewa 

 [Figs. 332 and 333] 

 1914 Zschokkella nova Klokacewa 1914 : 184-186 



Habitat: Gall-bladder of Carassius vulgaris; Russia? 

 Vegetative form: Not observed. 



Spore: Outline irregular. Observations on fixed materials alone. Two 

 large round polar capsules open at the side near ends. Sporoplasm with 

 two nuclei. On some spores, striations that run parallel to the sutural line 

 were observed. Dimensions: length 9.5 to 11.5/x, breadth 6.5 to In, 

 diameter of polar capsule 3 to 3.5/i.
