Euglypha umbilicata  Bonnet, 1959

Diagnosis: Shell robust, elongated oval, fundus semicircular in lateral view. Elliptical in cross-section, without keel. Elliptical pseudostome bordered by 10 scales with a long median denticle flanked by two small equal denticles on each side. Covering formed by small oval scales of 6 x 2 um overlapping very little, but assembled by an extremely abundant cement, which exudes so as to leave only the center of the scale free. This particularity gives the scales a characteristic umbilicate appearance. The scales on the base of the test are arranged without order

Dimensions: Length 44-46 µm, width 25-27 µm, thickness 18-22 µm.

Ecology: Soil mosses, Eastern Pyrenees, France.

Remarks: Bonnet, 1959: “Wailes (1915) reports, regarding Euglypha compressa Carter fa glabra Wailes, a great abundance of cement. This arrangement is exaggerated in Euglypha umbilicata, but the following characters, concerning Euglypha compressa: “… considerably compressed; transverse section lenticular with acute margins (…) bluntly denticulated or lobed scales” allow the two species to be easily separated.”
