Figures 31–35 in DNA sequencing reveals three new species of Chamberlainium (Corallinales, Rhodophyta) from South Africa, all formerly passing under Spongites yendoi

Figures 31–35: Chamberlainium occidentale habit and vegetative anatomy. (31) Rock fragment with holotype specimen showing the region (white arrow) of the holotype from which all analyses were done (L 3986120, gametangial and tetrasporangial). Scale bar = 10 mm. (32) 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 15/59). Scale bar = 50 μm. (33) Vertical section of the inner thallus showing cell fusions (f) between adjacent medullary filaments (UWC 15/56). Scale bar = 20 μm. (34) Vertical section of the outer thallus showing a single layer of epithallial cells (e) subtended by a layer of subepithallial initials (i). Note the cell fusions (f) between adjacent cortical filaments (UWC 15/59). Scale bar = 20 μm. (35) Vertical section of the outer thallus showing a single layer of epithallial cells (e) subtended by a layer of subepithallial initials (i). Note a cluster of bottle-shaped trichocytes (t) each separated by vegetative filaments (UWC 15/59). Scale bar = 20 μm.
