Fronds are cylindrical to slightly flattened. Branching is on one plane (distichous). Branchlets appear clustered, with a globular (botryoidal) form. Holdfast similar to creeping stem (stoloniferous). Dark red to red-brown. Up to 17 cm long (thallus).
This robust alga is usually conspicuous, often growing on rock platform edges below the low tide level. Algal derived toxins from Laurencia species have been identified in skin and ink of sea hares (opisthobranch molluscs), and are thought to play a part in predator defence.
