FIGURE 6 in Multilocus phylogeny reveals Gibsmithia hawaiiensis (Dumontiaceae, Rhodophyta) to be a species complex from the Indo-Pacific, with the proposal of G. eilatensis sp. nov.

FIGURE 6. Gibsmithia eilatensis sp. nov. A) Holotype, female gametophyte, DG234, Eilat, Israel. B) Assimilatory filaments comprised of main percurrent filaments (arrow), cortical filaments (arrowhead) and rhizoidal filaments (double arrowhead). Rhizoidal filaments with cells connected to neighboring rhizoidal cells. Slide DG219-2. Scale bar 200 μm. C) Female pre-fertilization stages among elongated, narrow assimilatory filaments. Slide DG234-3. Scale bar 200 μm. D) Hairlike extensions from apical cortical cells. Slide DG210-2. Scale bar 50 μm. E) Branched and unbranched "seirospore" filaments. Slide DG210-5. Scale bar 50 μm. F) Carpogonial branch laterally positioned on assimilatory filaments, with straight and obliquely (arrow) directed trichogynes. Slide DG210-1. Scale bar 50 μm. G) Carpogonial branch with laterally extended hypogynous cell (double arrowhead), small subhypogynous cell (arrowhead) and conical carpogonium (arrow) with straight trichogyne. Slide DG210-4. Scale bar 50 μm.
