Order Ectocarpales

Family Acinetosporaceae

Feldmannia globifera (Kützing) G.Hamel 1939: 67

Plants brown, 0.5 – 2 cm long, usually epiphytic, filamentous, uniseriate, irregularly branched close to the base; attached by entangled rhizoids. Filaments 25-50 (60) µm in diameter, cells 1-3 (-4) times as long as broad; filaments mainly of uniform diameter but gradually tapering distally. Meristematic zone of short cells at the base of each filament. Cells with numerous discoid plastids each with one pyrenoid. Plurilocular sporangia borne on 1-3 celled pedicels, rarely sessile; globular to ovoid with rounded apex, 60-100 µm long x 50-80 µm in diameter. Unilocular sporangia rarely seen; in same position as plurilocular sporangia, ovoid, sessile (35-60 µm diameter).

Collections, ecology and regional distribution

Recorded from Tsitsikamma to Kenton-on –Sea (31-39). Epiphytic on larger algae such as Codium spp.

World distribution: Widespread in temperate regions (Guiry & Guiry 2011).

Type locality: Yugoslavia (Womersley 1987).
