Selected citations: Womersley 1956: 357.
Thallus (Fig. 56D) light to medium green, loose-lying as masses of long strands (to 15 cm long) or entangled with other algae, in the uppermost sublittoral. Filaments unbranched, apparently without attachment cells, of similar diameter throughout (Fig. 57G). Cells (100–) 105–130 (–150) in diameter and L/B (1–) 1.5–2.5, often collapsing on drying; wall 3–7 µm thick; chloroplasts openly to fairly densely reticulate, with numerous pyrenoids; nuclei numerous.
Reproduction: Reproduction unknown.
Type from Tranquebar, India; in L (936, 249...72).
Selected specimens: Coffin Bay, S. Aust., upper sublittoral on flats (Womersley, 10.i.1951; ADU, A13756). Boat Lake, Robe, S. Aust., loose-lying, intertidal (Womersley, 28.ii.1983; ADU, A54005).
Distribution: India. Queensland.
In southern Australia, known from Walpole Inlet, W. Aust., Coffin Bay and Robe, S. Aust., and Swan Bay, Port Phillip, Vic. Also recorded from Port Adelaide, S. Aust. by Tate and Tasmania (?) by Lucas (see Womersley 1956, p. 357). Probably more widely distributed in sheltered waters.
Taxonomic notes: In contrast to Ch. capillaris which occurs in mid to upper eulittoral situations, Ch. indica seems to be a shallow water and floating or loose-lying upper sublittoral species. The size and proportions of the cells seems to separate these two species satisfactorily, but other names may prove to be synonyms of Ch. indica (e.g. Ch. brachygona — see Womersley 1956, p. 357).
