Rindifilum Malavasi, Klimešová, Lukešová & Škaloud.

This recently described genus differs from the previously mentioned Dilabifilum -like genera by the formation of ovoid to pyriform cells (the prostrate system), later developing into characteristic “hammer-shaped” cells ( Fig. 27 ). It is only the combination of these features, that makes this ulvophycean genus morphologically distinct. Rindifilum reproduces by the production of two or four autospores (Malavasi et al. 2022). The type species, R. verrucariae ( Malavasi & Škaloud 2022) was isolated from the freshwater lichens Verrucaria scabra and Verrucaria margacea (Malavasi et al. 2022) and to date, has not been observed in free-living state.
