Euglypha laevis
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 and probably part of a species complex. 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.
