FIGURE 5. A–G: Sertularella mixta sp. nov.—basal part of a stem above origin from stolon (A); stem internodes (B); normal (C) and aberrant (D) ramifications; hydrothecae (E); detail of a gonotheca (F); various shapes of the gonotheca (G). H–J: Sertularella tenella (Alder, 1857)—stem internodes (H); hydrothecae (I, J). K–P: Sertularella sp.—basal part of a stem just above origin from stolon (K); fragment of a stem (L); normal (M) and aberrant (N) ramifications; internodes and hydrothecae (O); hydrothecal apertures (P), normal (below) and hypertrophied (above); specimens from Stn. RHO, DS264 (L, O, P below), Stn. TIB, DS166 (K, M, N), and Stn. GNZ, S08 (P above). Q, R: Symplectoscyphus filiformis (Allman, 1888)—female (Q) and male (R) gonothecae.
