Order Cladophorales

Family Cladophoraceae

Chaetomorpha antennina (Bory de Saint-Vincent) Kützing 1847: 166

Plants leaf-green to dark green, a few to 8 cm tall, in brush-like tufts, attached by stoloniferous rhizoids. Individual filaments straight, rather rigid, unbranched, septate. Basal cells characteristically elongated, up to 7.5 mm long, thick-walled, with annulations near base. Cells 400-750 µm in diameter, 700-1000 µm long, becoming broader to barrel-shaped distally. Distal cells often losing contents via spore release, becoming transparent.

Recorded from Hluleka to northern Kwazulu-Natal (45-58). Epilithic in the eulittoral and shallow sublittoral zones.

World distribution: widespread in the temperate and tropical Atlantic, Indian and Pacific Oceans (Guiry & Guiry 2012).
