Radiofilum is a genus of green algae in the class Chlorophyceae. [1] It is a freshwater genus; they are often found in soft, boggy or acidic waters. [2]
Radiofilum consists of unbranched filaments of cells, surrounded by a very thin mucilage layer. Cells are bead-like, spherical or compressed. The cell wall consists of two halves, and there is a ring around the middle of the cell where the two halves are joined. Cells contain a chloroplast is parietal and contains one or more pyrenoids. [2]
The genus Radiofilum as currently circumscribed appears to be a polyphyletic grouping of species. Some work has been done to transfer species to other genera, [3] including Interfilum [3] and Flintia. [4] The type species, Radiofilum conjunctivum, belongs to the class Trebouxiophyceae and is phylogenetically close to the genus Microthamnion. [3]
