Diagnosis. 
Zoarium of loose, open tufts ; the branches dichotomize repeatedly, 
but the branches are never crowded or biserial. 
Zooecia long and narrow ; sometimes cylindrical, but typically 
they expand gradually to the distal end, so that the shape 
is subpyriform. The wall is smooth and slightly corrugated, 
•or punctulate. 
Peristomes usually low, and somewhat elongate ; but they may 
be a little raised and reflexed.
