Size (Zooecium): Length 360 µ; breadth 250 µ.

Encrusting, brownish purple in color. The size of the zooecia varies considerably. The front regularly rounded from side to side in young forms. As growth proceeds this feature seems to be lost. Tremocyst smooth with large pores and the ectocyst white in color with numerous pores. Large rounded primary aperture, broadly arcuated posture, which may even be semicircular. Condyles present, operculum, which is not conspicuously pigmented, clearly covers the aperture. The operculum bears small shining tubercle on each side proximal to the condyles. Peristome highly elevated, elevation greater in the case of mature zooecia possessing embryos. Umbo present.
