Aphanochaete is a genus of green algae in the family Aphanochaetaceae. The name Aphanochaete was given by Alexander Braun in 1850. The genus was actually described one year earlier by Carl Nägeli as Herposteiron, but the name Aphanochaete has been conserved against Herposteiron. Aphanochaete is a common epiphyte or aquatic plants or filamentous algae, such as Cladophora and Oedogonium. It is found in freshwater (rarely brackish water), particularly eutrophic and hard water, and has a cosmopolitan distribution.

Dimorphococcus is a genus of fresh water green algae in the family Scenedesmaceae. It is found as a component of the phytoplankton of freshwater ponds, lakes, and peat bogs. It is widespread, but usually not very common. Dimorphococcus is usually found in small colonies of multiples of four cells, surrounded by a gelatinous mass. Groups of four cells are further attached to each other via mucilaginous strands, which are the remnants of the mother cell wall. Cells are kidney-shaped to heart-shaped, 10–25 μm long and 3–8(–15) μm wide. Each cell is uninucleate (containing one nucleus) and has
