Thalli erect, red to deep purple in colour, attached by a small discoid holdfast. Stipe short and hard texture giving off branches which are deeply constricted at regular intervals giving rise to vesicular, globose segments (moniliform), 5 mm broad and 7 mm long. Cross-section of a segment shows a medulla of loose strands of slender non-pigmented medullary filaments and a cortex of 2 layers of cells, the outer epidermal layer made up of firmly coherent non-pigmented cells, the inner layer consisting of ovoid to elongate pigmented cells. Thalli up to 7 cm in height (Ref. 80758).
Obtained from natural stocks; a good source of agar; used for human consumption (Ref. 80758).
