Neodesmus

Neodesmus is a genus of green algae in the family Scenedesmaceae.
Neodesmus consists of colonies of two cells, termed coenobia ; these coenobia may be further arranged in a structured called a syncoenobium surrounded by a mucilage envelope. The cells are fusiform to cylindrical, 5 to 9 μm long and arranged obliquely next to each other. Syncoenobia may be up to 65 μm long. Each cell is uninucleate and contains one parietal chloroplast, each with a pyrenoid.
Neodesmus reproduces asexually by forming autospores; two spores are produced per cell. Sexual reproduction or flagellated life stages have not been observed in Neodesmus.
