Colony comprising encrusting uniserial runners, zooids having a cruciform budding pattern, with a lateral daughter zooid produced more or less at right angles (or shallower) from one or both of the distolateral pore-chambers, rarely from proximolateral pore-chambers (evident in some zooids), or budding is suppressed. Autozooids elongate-pyriform–claviform, with a proximally tapered portion of variable length [ZL 631–920 (805); DL 555–787 (653); CL 60–236 (152); DW 381–498 (439)], the gymnocyst proximally and laterally extensive, sloping to the substratum. Opesia and cryptocystal shelf surrounded by a raised elongate-oval cryptocystal rim that has linear granulations on the edge and inner face [CrL 307–504 (391); CrW 207–293 (257)]. Proximal cryptocystal shelf extensive, flat, evenly granular, the granules becoming a little more pustular at the edge of the opesia, the shelf attenuating distad to the opesiular constriction. Opesia about twice as long as wide, weakly dumbbell-shaped, being constricted by rounded projections that have a tubercular surface; distal (lower edge) and proximal opesial rims gently rounded, the proximal rim sometimes obliquely so [OpL 218–227 (223)]. Operculum flap-like, occupying area of opesia distal to constriction. Articulated spines perioral, six in total, more or less erect, not arching; no accessory gymnocystal spines. Ooecium hyperstomial, frontally a little longer than wide, smoothsurfaced with a short longitudinal peak that contains a small foramen [OoL 200–228 (214); OoW 225–252 (239)]; the distalmost pair of oral spines is so closely appressed to the sides of the ooecium as to leave a crease or furrow on each side when the spine is missing. Ooecial kenozooid projecting beyond ooecium, with a frontal cryptocystal area surrounding a foramen. No avicularia. Occasional kenozooids, usually roundly triangular, within the linear chains of zooids, typically (but not always) forming as a consequence of a developing zooid unable to complete its growth owing to collision with another zooid.
