Pseudulvella
Pseudulvella is a genus of green algae, in the family Chaetopeltidaceae. It is an epiphyte, found in freshwater or marine habitats.
Pseudulvella consists of filaments of cells that radiate outwards to form a disk. Cells are uninucleate, with a chloroplast containing a pyrenoid. Asexual reproduction is by quadriflagellate zoospores.
The species Pseudulvella americana is closely related to Chaetopeltis and morphologically similar, but lacks pseudocilia.
