Desmodesmus
Desmodesmus is a genus of green algae in the family Scenedesmaceae.[1] It is the only chlorophyll-containing organism known to have caused human infections in immunocompetent individuals. All known cases involved open injuries occurring in fresh water.[2]

Description
Desmodesmus consists of colonies of two, four, eight or 16 cells arranged in a row. Cells are ellipsoidal to ovoid, joined to each other by their longer sides. The terminal cells of a colony (and sometimes the medial cells as well) are usually armed with spines. Cell walls may also be covered in ridges, warts, and net-like structures. Cells contain one parietal chloroplast, containing one pyrenoid.[3]
Habitat
Desmodesmus is found in the plankton of habitats such as ponds and lakes, particularly in eutrophic waters.[4] It is one of the most common types of freshwater plankton.[3]
