Description
Zoarium ramose, monticules flush, center of stereom, peristomes elevated. Autozooecia in endozone contiguous, walls thin, granular, diaphragms few. Autozooecia in exozone isolated by vesicles, oval in cross section, diaphragms closely spaced. Wall with dark, granular, boundary zone and thick, gran-ular-prismatic cortex.
