Rhogostoma spec. - Kloosterhaar and R. minus (photomicrograph: Yana Eglit)
Genus Rhogostoma Belar, 1921
Belar (1921) described two Rhogostoma species that differed from freshwater Lecythium in four respects:
- having a narrow crack-like, not a large round, aperture;
- being filose not reticulose;
- being several times smaller (R. minus 10-12 µm, R. schuessleri 15 µm);
- thecae having bilateral not radial symmetry.
