Abstract:
The first occurrence of Palisada maris-rubri (K.W. Nam
et Saito) K.W. Nam (Ceramiales, Rhodomelaceae) from
the Mediterranean Sea, is reported. To date the species
was known only from tetrasporic specimens from the
type locality (Ras Muhammed, Sinai, Egypt, Red Sea).
Mediterranean thalli share nearly all vegetative and
reproductive features with Red Sea specimens showing
more robust thalli with axes to 3 mm broad and ultimate
branchlets to 1000 mm broad, absence of intercellular
spaces between medullary cells and epidermal
cells in transverse section with a palisade arrangement.
Male and cystocarpic thalli are recorded for the first
time. Moreover, the analysis of characters of three
species of Chondrophycus previously known from the
Mediterranean Sea (C. patentirameus (Montagne) K.W.
Nam, C. tenerrimus (Cremades) G. Furnari et al. and C.
thuyoides (Kützing) G. Furnari) led us to conclude that
they belong to the genus Palisada. The following new
combinations are formally proposed: P. patentiramea
(Montagne) Serio et al., P. thuyoides (Kützing) Serio
et al., P. tenerrima (Cremades) Serio et al.
