Difflugia lucida
Difflugia lucida, 64 and 68 µm

 
Difflugia lucida Penard, 1890

Diagnosis: Shell compressed, covered with flat quartz particles. Living individuals accumulate mainly inorganic material round the elliptic aperture. This aggregation of particles is probably drawn into the shell when the amoebae encysts and is lost when the cell dies. Nucleus with a central nucleolus.

Dimensions: ca. 64-70 µm
