The outline is undulated, sometimes lobate, even with pointed prejections. The bottom is rounded, more or less smooth, in some individuals with flat protrusions or depressions. The walls are usually steep, perpenticular or slightly overhanging; borings often occur in large groups. The usual dimension at the surface of sibstrate is c. 50 mm, depth 10-15 mm.
