General Biology Additional InformationRhodothamniella floridula is perennial. The hair-like filaments are approximately 20-25µm in diameter. The species has been noted to trap sand and mud in a layer up to 5cm thick (Lobban & Wynne, 1981).

Dixon & Irvine (1977) observed that the growth of Rhodothamniella floridula (as Audouinella floridula) is much faster in winter, whilst in the summer the spongy cushion can become bleached or disrupted.
