Figures 7–11 in DNA sequencing reveals three new species of Chamberlainium (Corallinales, Rhodophyta) from South Africa, all formerly passing under Spongites yendoi

Figures 7–11: Chamberlainium capense habit and vegetative anatomy. (7) Rock fragment showing holotype specimen (white arrow) (L 3986119, tetrasporangial). Scale bar = 20 mm. (8) Encrusting to variably lumpy and slightly protuberant, epilithic thalli showing crusts abutting and easily discernible. Scale bar = 10 mm. (9) Vertical section through the margin (black arrow) showing the monomerous thallus construction with plumose medulla (M) giving rise to cortical filaments (C) that terminate in a single layer of epithallial cells (black arrowhead) (UWC 16/17). Scale bar = 50 μm. (10) Vertical section of the inner thallus showing cell fusions (f) between adjacent medullary filaments (UWC 16/17). Scale bar = 20 μm. (11) Vertical section of the outer thallus showing a single layer of epithallial cells (e) subtended by a layer of subepithallial initials (i). Note the paired, bottle-shaped trichocytes (t) (UWC 16/24). Scale bar = 20 μm.
