FIGURE 6. Scrupocellaria frondis Kirkpatrick, 1890. A, B, D, specimens found on algae from Alagoas, NE Brazil. C, E, F, MTQ G25165. A, frontal surface of bifurcating branch, note the ovicelled zooid to the right of the bifurcation. B, basal surface of branch bifurcation. C, frontal surface of branch bifurcation; note the frontal avicularium on the axial autozooid. D, basal surface of branch bifurcation with a single axial vibraculum. E, frontal surface of branch bifurcation; note the frontal avicularium on the axial autozooid. F, several autozooids, one ovicellate and the others with developing ovicells; note the most proximal outer spines on the two autozooids to the left with the characteristic three or four frontal tines. Scale bars: 100 µm (A–F).
