Species

Chaetomnion is a genus of green algae in the family Chaetophoraceae. It has mainly been reported from Asia, and is epiphytic on the leaves of Potamogeton, an aquatic plant.[2]

Chaetomnion consists of thalli forming tufts of branched filaments growing in a radial pattern, growing up to 1 mm wide. The primary filaments are prostrate, while secondary filaments are erect and branching; filaments terminate in a long, hyaline unicellular hair. Cells are short and barrel-shaped, 8–17 μm in diameter, and contain a parietal chloroplast with one or two pyrenoids.[2] Chaetomnion reproduces asexually. It reproduces via large aplanospores, which are 35–48 μm long, borne on the ends of the secondary branches.[2] The two species, C. nakaoi and C. pyriferum, are distinguished by the placement of their terminal hairs.[3]
