Groups of tubes which may reach well over 1 metre tall.
The tubes are rubbery. This is the typical A. archeri, mauve to purple in colour and with pronounced bumps and ridges over the outer surface. The inner surface is remarkably smooth.
These reach largest size in turbid water, where they may buckle and bend apparently under their own weight.
