Culture studies on Pterocladia melanoidea (Schousboe ex Bornet) comb. nov. (Gelidiales, Rhodophyta)

Gelidiella minimasp. nov. (Rhodophyta) from Victoria, Australia: Implications for the generic classification of the Gelidiaceae

“…The cystocarp development of Pterocladia melanoidea (Schousboe ex Bornet) Fredriksen et Rueness as described by Fredriksen & Rueness (1990) is very similar to that of G. minima and P. capillacea. P. melanoidea had, for many years, been referred to the genus Gelidium, but cystocarps were unknown.…”

“…However, in a manner similar to P. capillacea and G. minima, the carposporangia arise in chains in the vicinity of the axial cell on the floor of the cystocarp. P. melanoidea is of further interest in that rhizines are very scarce in the medulla, and entirely absent in the younger parts of the fronds (Fredriksen & Rueness, 1990).…”

A New Species from the Canary Islands Increases the Diversity of the Red Algal Genus Pterocladiella in the Northeastern Atlantic

“…However, P. melanoidea (type locality: Tangier, Morocco, and also reported in the Mediterranean Sea and Northeast Atlantic) is distinguished by larger plants (up to 40 mm in height) with thin erect axes subcylindrical to flattened, irregularly branched including opposite at right angles or pinnate branches up to two orders, larger ovoid cortical cells (6–12 µm long), and cystocarp of triangular outline seen in transverse section [ 45 , 46 , 47 , 49 ]. Pterocladiella canariensis is also distinct from ‘ Gelidiella calcicola’ Maggs and Guiry [ 21 ] (type locality: Carraroe, County Galway, Ireland), a morphologically similar taxon that has been erroneously identified as P. melanoidea in different localities of the NE Atlantic between Brittany and Portugal [ 22 , 50 ]. According to Boo et al [ 19 ], this taxon belongs to Pterocladiella but it is phylogenetically distantly related to specimens identified as P. melanoidea in the Mediterranean Sea.…”

“…According to Boo et al [ 19 ], this taxon belongs to Pterocladiella but it is phylogenetically distantly related to specimens identified as P. melanoidea in the Mediterranean Sea. ‘ Gelidiella calcicola ’ is characterized by plants up to 30 mm in height with terete to flattened erect axes, larger polygonal cortical cells (5–18 µm wide), triangular cystocarp in transverse section, and lacks sterile margin in tetrasporangial sori [ 21 , 22 , 50 , 51 ].…”

“…Οι σημαντικότερες αλλαγές της ονοματολογίας περιλαμβάνουν τα παρακάτω είδη: Το είδος Galaxaura oblongata (Ellis & Solander) Lamouroux μεταφέρθηκε στο γένος Tricleocarpa Huisman et Borowitzka (Huisman & Borowitzka, 1990). To είδος Gelidium melanoideum Schousboe ex Bornet μεταφέρθηκε στο γένος Pterocladia J. Agardh (Fredriksen & Rueness, 1990). Ορισμένα είδη από το γένος Callithamnion Lyngbye επαναμεταφέρθηκαν στο γένος Aglaothamnion Feldmann-Mazoyer (αναλυτικά δίνονται οι αλλαγές στις περιγραφές των αντίστοιχων ειδών).…”
