Spumochlamys perforata Kudryavtsev, Pawlowski and Hausmann, 2009

Diagnosis: test with a flexible aperture, which may open as wide as ca 0.3-0.8 times the test diameter (average 0.6) depending on the physiological condition of the cell. The dorsal part of the test wall consists of irregular alveoles;  test surface uneven, with numerous pores; single vesicular nucleus; central nucleolus.

Dimensions: test diameter 36-61 µm (mean 45 µm), diameter of aperture 12-39 µm (average 26 µm) (n=100);  pores in the test wall ca 0.2-0.9 µm in diam. (average 0.4 µm); nucleus 6-12 µm in diam. (average 9 µm); central nucleolus 4-9 µm in diam. (average 6 µm).

Type habitat. Dry epiphytic moss Dicranum scoparium, city of Saint-Petersburg, north-western Russia.
