Description: Massive-lobose; substantial growths often with massive tubular processes. The processes are simple or coalescent, often fusing at the bases and so resembling malformed, hand-like structures. Sometimes the thicker branches have a longitudinal groove in one side (? is this a common feature?). Yellow to orange. Are there any other colours? "Firm, compressible." "Oscules are usually small, scattered and numerous".

Distribution: "British Isles; France; Spain." Recent diving records from the Scilly Isles and Galway Bay.
