Ceramium pallidum is a small marine alga. It occurs in waters off of Europe and Africa (Morocco).[1]

Description

Ceramium pallidum is a small filamentous, regularly branched delicate alga.[2] The axes can reach 12 cm long and are attached by multicellular rhizoids. The structure is basically of a monosiphonous axis and erect branches with strongly inrolled apices. The segments are either fully corticate or ecorticate at the internodes which gives a banded appearance.[3]

Reproduction

The gametophytes are dioecious or monoecious. Spermatangial sori occur on young axes and cystocarps contain numerous carposporangia. The tetrasporangia occur in whorls on the younger branches.[3]

Habitat

Epiphytic on other algae in the littoral zone as well as the sublittoral.[3]

Distribution

Recorded from the coasts of Great Britain, Ireland, France, the Netherlands, Norway, Portogal, Spain (including the Canary Islands), and Morocco.[1][3]
