[2] Members of this genus are found in marine (particularly intertidal) or terrestrial habitats.

Therefore, the genus was renamed to Rosenvingiella by Paul Claude Silva in 1957, honoring its original author.

The filaments are attached to a substrate via a unicellular rhizoid, either found singly or in pairs.

Molecular phylogenetic analyses have shown the two genera to be separate: they can be distinguished by morphological characters of the gametangia and rhizoids.

[6] The genus Rosenvingiellopsis was also separated from Rosenvingiella based on molecular data.
