Codium tenue (Kützing) Kützing 1856: 33-34

Thallus light green, bushy, erect, flaccid, to 45 cm tall, closely divaricately dichotomously branched, dichotomies flattened and widened (to 2.2 cm in lower thallus), interdichotomies terete, 4-5 mm wide in lower thallus, narrowing to 1-2 mm near branch tips. Utricles from mid-thallus turbinate, quadrate (rectangular), obovate or pyriform, 330-450 µm long, and pyriform or club-shaped, 480-760 µm long, apices broadly rounded or slightly flattened. Hairs or hair-scars frequent, 1-3 per utricle, just below apex. Gametangia ovoid or sometimes spindle-shaped, 122-238 µm long, on pedicels, usually below middle of utricles.

World distribution: Also recorded from Mauritius, Senegal, Sudan and various localities in the Indian and Pacific Oceans (M.D. Guiry in Guiry & Guiry 2014).
