in diameter, frequently enveloping the substrate. Ancestrula subcircular to elliptical, smaller and with a narrower cryptocyst than budded autozooids, the periancestrular vibracula and daughter zooids arranged in a clockwise spiral pattern. Pore-chamber windows absent. Autozooids distinct, bordered by grooves, oval, elongate (mean L/W = 1.46). Gymnocyst minimal, smooth, convex. Cryptocyst very thin proximally and laterally, disappearing distally, sloping steeply inwards, markedly transversely crenulate. Opesia occupying almost the entire frontal surface, oval, pear-shaped or irregular, narrower distally. Vibracula globular to oval, present distally of each autozooid; opesia occupying almost the entire frontal surface, figure of 8-shaped, constricted in the middle by two small rounded teeth. Ooecia presumed absent. Kenozooids marginal, terminal, budded on the underside of the substrate, irregularly shaped; gymnocyst variably developed, cryptocyst crenulate, forming a depressed shelf with a small, circular or slit-like, central opening. Intramural buds common in both autozooids and vibracula.
