Diagnosis. 
Zoarium with a narrow stem, widening into a thick horizontal 
expansion, from which rise numerous short, blunt fasciculi. 
The zoarium seen from above is roughly triangular. 
The head includes about ten bundles of zooecia, which rise upward 
in sharp spikes. The bundles are grooved longitudinally and 
branch dichotomously ; the sides when worn appear punctate, 
but in well-preserved specimens are marked with longitudinal 
ridges, decorated by small tubercles.
