Description
Solitary, or in some, with few offsets, corallites calceoloid, calice with subsemicircular operculum of dense sclerenchyme, with tubular holdfasts, septa incomplete, of isolated short, fine, cornlike trabeculae developed in radial rows sporadically on dissepiments and tabellae, in places coalesced radially into short, thin septal segments at or near periphery, or thickened and coalesced radially and laterally to form peripheral stereozone on counter (flattened) side or on both sides of corallum, part of counter septum near periphery may be expanded laterally and anteriorly as calical knob consisting of long slender trabeculae radiating obliquely upward from longitudinal axis, in some, septum in each loculus neighboring counter septum long like major septum, dissepiments and tabellae numerous, seldom thickened, not readily distinguishable in size or inclination
