Scutiglypha acanthophora
Euglypha (Scutiglypha) acanthophora, 75 µm – stacked image

Euglypha acanthophora (Ehrenberg, 1841)

Diagnosis: shell ovoid or slightly elongated towards the aperture, not compressed; fundus with 1-9 long, usually a little bended spines, which are in fact elongated scales; aperture circular, bordered by up to three rows of serrated scales; body scales elliptical or nearly circular with a tooth-like projection on the posterior edge; plasma and pseudopodia normal.

Dimensions: literature 55-84 µm; my measurements 66-97 µm

Ecology: Sphagnum and other mosses, also in sediments and between waterplants.

Remarks: The scales are scutiform, with a small tooth-like projection on the posterior part. The spines are elongated shell scales, tapering towards a sharp point.

It’s probably not a separate species, but E. acanthophora without spines.
