Description
Size (Zooecium): Length 315-430 µ; breadth 300-320 µ.

Zoarium encrusting, but occasionally may grow into free unilaminar fronds, distinct, whitish in hue. Zooecia arranged in longitudinal lines, separated by thin calcareous lines. Marginal areola conspicuous and large. Zooecia rectangular, but looses the typical shape when superposed. Front convex and in young, zooecia raised. Orifice circular, or slightly triangular proximally. Peristome tubular, moderately developed, smooth. Primary orifice could be seen through the peristome. Lyrules short and truncate, condyles small incurved. Avicularia numerous. Two types of small avicularia, one acute and the other rounded, distributed in almost every zooecium. They may be directing proximally or distally, and in rare cases, transversely. When transverse, usually occupy the lateral side of the peristome. Large spatulate avicularia present, rare, directed proximally or distally, mandible long and with spatulate or rounded tip. Ovicells globose, slightly immersed, ectooecium present at the rim. Peristome may invade the proximal rim. Ovicells porous, pores usually placed on small tubercles.
