Euglypha laevis
Shell 24 and 28 µm

 

 

Euglypha laevis (Ehrenberg, 1845)

 

Diagnosis: shell small, oviform, smooth, compressed, in cross-section broad-elliptical; aperture elliptical to sub-circular; aperture bordered by pointed scales; body-scales oval; nucleus with one central nucleolus.

 

Dimensions: literature 22-60 µm.

 

Ecology: Sphagnum and other mosses, also in sediments.

 

Remarks: This is the smallest Euglypha species. Because of its dimensions, the fine shell structure is very hard to observe. Scales very obscure, imbricated exclusively at the anterior half of the shell. Spines never present.
