Description. Colony erect, branched, internodes comprising 5–12 zooids. Lateral edge of internode almost straight to slightly curved; chitinous joint passing across gymnocyst and below or slightly overlapping opesia in both outer zooids (C and D) of bifurcation, and across proximal gymnocyst of inner zooids (F and G). Autozooid subelongate, slightly narrower proximally, 0.400– 0.615 mm long, 0.190–0.220 mm wide, with smooth proximal gymnocyst. Opesia oval, occupying distal half (approximately) of zooid, cryptocyst very narrow, inconspicuous. Scutum inserted at midline of inner edge of opesia, branched, occupying almost entire opesial area, slender, flattened, branched 2–3 times, with 8–13 stout projections at distal tips; scutum angled at 115–155°, with first branches about 0.045–0.060 mm wide, secondary branches about 0.035–0.045 mm. Zooid spines as follows: 1 long distal spine, 3 outer spines, 1–2 inner spines; most proximal outer and inner spines directed frontally; axial zooid with 5 distal spines. One distolateral avicularium sometimes present on each zooid, distolaterally directed and obscured by outer distal spines; rostrum triangular, with slightly serrated lateral edge, mandible triangular. A large avicularium present on gymnocyst of some zooids, sometimes robust, rostrum serrated laterally, slightly curved and directed forwards; mandible triangular with hooked tip. A basal vibracular chamber often present proximally on basal surface of each zooid, 0.130–0.140 mm long, 0.100– 0.135 mm wide, rarely conspicuous in frontal view; setal groove directed transversely, straight, with smooth seta longer than one zooid length. A single axial vibraculum. A rhizoidal foramen on proximal outer corner of each basal vibracular chamber, absent in axial vibracula. Rhizoids smooth, attachment disc-like, with some projections at distal end. Ovicell hyperstomial, hemispherical, with 12–18 small rounded pores; 2 outer and 2 inner distal spines in ovicelled zooids.
Remarks. This species was previously recorded by numerous authors as S. reptans. Scrupocellaria ellisi n. sp., named after the British naturalist John Ellis (1714–1776), is distinguished by smooth (not hooked) rhizoids, robust more-branched scuta and ovicells with small rounded pores.
Distribution. Widespread in North Sea, British Channel, Irish Sea, Celtic Sea; Adriatic and Tasmania.
