1908 Hoferellus cyprini Mercier 1908 : LHI-LIV 



1910 Hoferellus cyprini Plehn 1910 : 20-22 



Habitat: In lumen and epithelial cells of renal tubules of kidney of 

 Cyprinus carpio L.; France and Germany. 



Vegetative form: Young trophozoites live in epithelium. Adults free 

 in the urinary tubules. Form rounded or oval. No clear differentiation of 

 protoplasm. Pseudopodium unobserved. Endoplasm contains numerous 

 granules and many nuclei. Each pansporoblast forms two spores. Smaller 

 individuals 20 to 30/x in diameter. Polysporous. 



Spore: Pyramidal with two short tail-like processes at the posterior 

 end, which are formed from the shell-valves like those of Henneguya. 

 Between these two processes, rarely small protoplasmic pointed processes 

 occur. Each shell-valve has 9 to 10 longitudinal striations on it. Two 

 polar capsules at the anterior part, show clearly the coiled polar filaments. 

 Sporoplasm has two neclei and an iodinophilous vacuole. Dimensions: 

 total length 10 to 12^, breadth 8^, tail-process 2/t long, polar capsule 2>n long.
