Family Cladophoraceae

Cladophora sericea (Hudson) Kützing 1843: 264

Plants pale to grass-green, erect, up to ca. 10 (-20) cm tall, attached by rhizoids. Growth mainly scattered intercalary; branching of terminal systems acropetal to irregular, apical branch systems often of main axis with long secund series of short branchlets. Main axis pseudodichotomously branched. Laterals cut off via an oblique cross wall that moves into a transverse position in older branches. Branch angle of laterals off main axis 30-45o, up to 3 laterals per cell. Apical cells tapered with blunt tip, 15-70 µm in diameter, cells of main axes up to 50-170 µm in diameter, 2-10 times longer than broad.

 Description from Stegenga et al. (1997) and Leliaert & Coppejans (2003).

Collections ecology and regional distribution

Recorded from Melkbosstrand on the west coast to De Hoop (15-24) (Stegenga et al. 1997). Found in the eulittoral zone and rock pools, also able to grow in low salinity water (Leliaert & Coppejans, 2003).

World distribution: Virtually worldwide in temperate and tropical waters (Guiry & Guiry 2012).

Type locality: Kent, England (Leliaert & Coppejans 2003).
