Synonym(s)

General environment
This is a Marine species.

Description
Plants complanate, subdichotomous or irregularly-alternately branched, delicate and diaphanous in texture, medium-brown in colour, lighter brown in young specimens. Fronds with very prominent midribs but without lateral veins. Blades monostromatic peripherally, bilayered adjacent to midribs; cells square, 3244 µm thick. Margins usually dentate. Hair tufts forming lines parallel to the midribs. Multicellular branched rhizoids in the frond margins, more abundant in the young parts of the fronds. Gametophytes unknown. Sporangia forming two broad continuous lines immediately adjacent to the midribs on both faces of the fronds.

Habitat
In the Mediterranean this species grows mainly in Posidonia oceanica beds and on maërl-strewn bottoms at up to 40 m depth, although also occasionally in eulittoral pools. On Atlantic coasts it occurs between 3 and 20 m depth on rocky bottoms.

Key characteristics
In regard to the substantial monostromatic portions of the blades in D. lucida only D. australis Sonder, D. gracilis Womersley and D. plagiogramma (Montagne) Vickers display this feature. However, as illustrated by Allender & Kraft (1983), both D. australis and D. plagiogramma have much narrower monostromatic zones than does D. lucida. These claims, based on Australian populations, conflict with statements by Taylor (1972) and D.S. Littler & M.M. Littler (2000) to the effect that blades of D. plagiogramma in the Caribbean are monostromatic throughout, which is an issue that needs to be reexamined and clarified. Nevertheless, D. lucida lacks the lateral veins of D. plagiogramma, lacks the reflexed lines of sporangial sori of D. australis, and has marginal teeth and lateral rhizoids that all three other species lack.
