Order Cladophorales

Family Cladophoraceae

Cladophora sp. I indet (see Stegenga et al. 1997: 111, Plate 21:4)

“Plants forming minute dark green cushions 1-5 (-15) mm high and of about the same diameter. Thalli consisting of dense bundles of branched filaments, the basal part more or less endophytic in crustose algae. Organisation of the thallus feebly acropetal, both apical and intercalary cell divisions occurring: thallus apices often strongly curved. Branching virtually subdichotomous, laterals frequently reaching the same length as main axes. Laterals cut off via an almost transverse septum. Remaining appressed against the main axis; usually not more than one branch per cell. . Apical cells 30-45 µm in diameter, cylindrical with rounded apex. Main axes 40-65 µm in diameter, cell length from 1-3 times the diameter in distal portions to 4-6 (-15) times in proximal portions. Fertile cells developing in terminal branch sections, swollen, up to 70 µm in diameter, little longer than broad”. (Description from Stegenga et al. 1997).

Collections ecology and regional distribution

Recorded from False Bay to Goukamma oyster beds (17-29). “Often semi-endophytic on crustose algae, both fleshy (Ralfsia) and calcareous (Corallinaceae), also on the reef worm Gunnarea: in the intertidal almost up to high water mark”: Stegenga et al. (1997).

World distribution: Unknown
