Abstract:
A new genus of gelidioid red algae, Gelidiophycus, is described. Separated from Gelidium on the basis of a molecular
phylogeny and morphological characters, it contains two species, Gelidiophycus freshwateri sp. nov. and G. divaricatus comb.
nov., distributed in East Asia. Our rbcL and cox1 phylogenies revealed close relationships of Gelidiophycus with the Capreolia
group in Australasia and unidentified taxa in Chile. Gelidiophycus is characterized by repent thalli and lateral branches arising
at almost right angles. The occurrence of tetrasporophytes, male and female gametophytes, and carposporophytes in the field
indicate that both species have the triphasic type life history, different from Capreolia. Gelidiophycus freshwateri occurs in
Korea, China, and Japan, and G. divaricatus is found in Hong Kong. We discuss Gelidiophycus and its two species and provide
keys, descriptions, and illustrations.
