Pseudodifflugia fascicularis Penard, 1902

 

Diagnosis: shell chitinoid, pyroid, narrow elliptical, with a faint indication of a neck, not compressed, partly covered with some mineral particles and diatom frustules; Plasmaboy visible through the shell wall. Pseudosome circular, but hard to observe because of a bundle ('fascis') of mineral particles; cytoplasm and nucleus normal; filopodia long and straight, branching but not really anastomosing.

 

Dimensions: literature 17-50 µm, seldom longer. My measurements: 24 µm.

 

Ecology: detritus
