Cladophora lehmanniana (Lindenberg) Kützing 1843: 268.

Phylum Chlorophyta – Order Cladophorales – Family Cladophoraceae

Selected citations: van den Hoek 1963: 122, figs 392–408.

Thallus (Fig. 64B) light to medium green, single or in clusters, forming pompons when small and fastigiate tufts when large, 2–15 (–30) cm high with the pseudodichotomous axes arising from a base of matted rhizoids from the lowest cells; epilithic or epiphytic; filaments tapering only slightly, much branched from almost every cell above with straight to falcate or refract and often unilaterally arranged branchlets (Fig. 65C). Growth acropetal and mainly apical above, with intercalary divisions in the mid and lower thallus cells thus separating the laterals by 2–8 cells but with few branches arising below intercalary cross walls; each parent cell bearing 1–2 (–3) laterals mostly at an angle of 45° or more, sometimes less; basal cross walls of laterals oblique to parent cell, later often becoming almost horizontal.

Apical cells (80–) 100–120 (–160) pm in diameter, L/B 3–8, cylindrical, sometimes slightly inflated, with rounded apices; ultimate branch cells (85–) 100–120 µm in diameter, L/B 2–6; lower thallus cells (140–) 180–220 (–250) µm in maximum diameter, L/B 2–7; ratio of lower cell to apical cell diameters 1.5–2.5; cell walls thin to moderately thick (10–15 µm) near the base.

Reproduction: Reproduction by somewhat inflated apical or subapical cells forming zooidangia; (Fig. 65D); in Europe by quadriflagellate zoospores (van den Hoek 1963, p. 124).

Type from Helgoland; isotypes in L (937, 281 .. . 47) and LD (9341–9343).

Aust., low eulittoral (Womersley, 8.i.1951; ADU, A13802). Barker Rocks, Yorke Pen., S. Aust., upper sublittoral on Cladostephus (van den Hoek 81/65, 20.ix.1981; ADU, A52670). Pondalowie Bay, Yorke Pen., S. Aust., mid eulittoral on wave-washed ledges (van den Hoek 81/58, 19.ix.1981; ADU, A52616). Pondalowie Bay, Yorke Pen., S. Aust., shallow sublittoral rocks within sheltered inner bay (Lipkin, 19.ix.1981; ADU, A52617). Robe, S. Aust., upper sublittoral pools in bay (Womersley, 11.xii.1969; ADU, A34858-"Marine Algae of southern Australia" No. 222). Apollo Bay, Vic., low eulittoral pools, on Cladostephus (Womersley, 26.i.1964; ADU, A28054). Penguin, Tas., mid eulittoral (Curtis, 20.i.1954; HO, 44870). Orford, Tas., mid eulittoral pools (Kingsbury, 14.ii.1980; HO, 41515).

Distribution: Warm temperate Atlantic and Mediterranean coasts of Europe (van den Hoek 1963, p. 125).

In southern Australia, from Geraldton, W. Aust. to Walkerville, Vic., and around Tasmania, in pools and shallow water under moderate water movement.

Taxonomic notes: Cl. lehmanniana is closely related to the more robust Cl. valonioides (apical cells over 150 µm in diameter) and to the less robust Cl. laetevirens (apical cells mostly less than 80 µm in diameter). These three species have similar thallus organisation and development but are distinct on cell dimensions.
