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.
