MICROSPORIDIA 



G77 



B. eriodrili J. (Fig. 292, g). In the lymphocytes in the posterior 

 portion of the body cavity and nephridia of Criodrilus lacuum; in- 

 fected lymphocytes become hypertrophied from 15/* to 200-400/* in 

 diameter; the infected part of the body appears yellowish; spores 

 20-22/* by 1/* (Janda); 15.5-17/* by 1.2-1.4/* up to 24-25/* by 1.6m 

 (commonly 18-20/* by 1.4-1.5/*) (Jirovec).

Genus Cougourdella Hesse. Spore cylindrical, with an enlarged 

 extremity, resembling the fruit of Lagenaria cougourda. 3 species 

 (Hesse, 1935).
