in height, from a ribbon-like encrusting base. Branching angle usually between 70° and 90°. Encrusting part composed of elongate-rectangular zooids arranged in bi- to triserial ribbons that may bifurcate. Broad base around erect part composed of frontally thickened auto- and kenozooids. Autozooids separated by suture between slightly raised thin ridges; frontal shield umbonuloid, convex, imperforate except for single row of small but distinct and widely spaced areolar pores, its surface a meshwork of smoothed shallow ridges or nodules and pits; frontal shield distally rising to form peristome with suborbicular aperture. Narrow distalmost part of peristome formed by vertical extension of distal zooid’s frontal shield.
