Diagnosis. 
Zoarium irregular, lobed or subcircular, often of two flabelliform 
branches. 
Zooecia cylindrical, long. The zooecia are usually visible 
throughout, but are sometimes crowded at the margin. The 
walls of the zooecia are smooth, or minutely granulate or 
faintly wrinkled. 
Peristomes low. The apertures of the zooecia are irregularly 
distributed. 
Gonocysts elliptical ; the transverse width is twice as great as 
the radial width.
