Description
Zoarium ramose. Monticules with ring of larger zooecia, lunaria in part radially arranged. Autozooecia thin-walled in endozone, isolated by vesicular tissue, subcircular in cross section in exozone, narrowly isolated by vesicles, walls laminated, thick laminated lining in exozone, some mural tubuli in lining. Diaphragms closely spaced in outer endozone and exozone, thin, flat to concave. Lunaria in outer endozone and exozone, of light-colored and dense calcite. Vesicular tissue long blisters in endozone, becoming more subquadrate at zooecial-bend region, decreasing in height outward in exozone, walls and roofs laminated, containing small acanthostyles or tubuli.
