[Figure 131] 



1875 Euspora fallax Schneider 1875:583 



Euspora: Sporonts biassociativ€|i ellipsoidal. Measurements not 

 given. Ratio length protomerite : total length primite : : 1 : 6 ; width 

 protomerite : width deutomerite : : 1 : 2.5. Protomerite of primite 

 spherical, deep constriction at septum; deutomerite ellipsoidal, widest 

 through middle or just posterior to middle, posterior end flattened. 

 Nucleus spherical with one karyosome. Endocyte dense except in ante- 

 rior third of protomerite, where there is a distinct conoidal area of less 

 dense endocyte. 



Cysts spherical, dehiscing by simple rupture. Spores prismatic, 

 square cornered, pentagonal in optical view. 



Taken at Roscoff, France. Host : A Melolonthid (Rhizotrogus aes- 

 Asida servUlei Soil. Habitat : Intestine.

 drical. Maximum length of association of two, 20/i. "Width not given. 

 Ratio length protomerite : total length primite :: 1 : 10 to 1 : 12; 

 width protomerite : width deutomerite : : 1 : 2. Protomerite sub- 

 globular, depressed. Deutomerite elongate cylindrical. Epimerite a 

 small simple hyaline papilla. Myocyte well developed. Nucleus spheri- 

 cal with one small karyosome.
