Descriptions

Shell brownish, of small siliceous plates and grains, closely cemented upon a chitinous pellicle. Superior lip with a row of pores. Habitat mosses. (ref. ID; 1923)
The shell is dark brown, oval or circular, and hemispherical or spherical in lateral view. The shell surface is usually rough, except around the aperture where it is smooth. The aperture is an invaginated narrow, elongated slit, whose inner lip is depressed and outer lip incurved with a median extension. Large pores surround the aperture, they are more numerous on the outer lip and extend laterally over the apical margin. Some variation of the aperture and surrounding pores has been observed (Cash et al. 1919). (ref. ID; 3686)
Shell composition is agglutinate; position of aperture is ventral. (ref. ID; 6790)
