Gelidium pulchellum (Turner) J.V. Lamouroux
Description: Cartilaginous, regularly or irregularly bipinnate,
dark red-brown fronds, 50-100 mm high, arising from a creeping base. Main
axes narrow, cylindrical, somewhat flattened above. Ultimate branches short,
pointed at first, later ± spathulate, particularly when reproductive.
Appearance variable with habitat and time of year.
Habitat: Abundant in and around tidal pools in mid- and
lower intertidal in high-light situations. Generally epiphytic on Corallina officinalis and growing on limpets. Widely distributed, common.
Similar species: Gelidium spinosum is more flattened and more regularly pinnately
branched and occurs in lower-shore habitats and in the subtidal. Pterocladiella capillacea is much less common, more regular and pyramidal in outline.
Key characteristics: Pinnate branching, mid- and lower-intertidal
low-light habitats, and slighly flattened main axis.
