The genera Hypnea and Calliblepharis of the family Cystocloniaceae are discriminated by their female reproductive structure, especially in the formation of carposporangia and gonimoblasts. Hypnea saidana, once classified based on obsolete evidence, has not been studied phylogenetically using molecular analysis and detailed reproductive structure though it shares many morphologic features with the genus Calliblepharis. To provide better understanding of generic relationship of H. saidana with Hypnea and Calliblepharis, we carried out molecular analyses using the nuclear-encoded small subunit ribosomal DNA (SSU) and chloroplast-encoded large subunit of the RuBisCO (rbcL), and exact morphological observations focusing on the reproductive structures of wild specimens. Our molecular phylogeny showed that H. saidana is closely related to Calliblepharis, but distinct from the clade of Hypnea. Female reproductive structure of H. saidana characterized by upwardly developing chains of carposporangia, central reticulum of cell, and gonimoblast filaments not connected to the pericarp provides definite evidence to assign the taxonomic position of this species to Calliblepharis. Based on our combined molecular and morphological analyses, we have proposed Calliblepharis saidana comb. nov., expanding the distribution of Calliblepharis habitat from the eastern Atlantic South Africa, the northern Indian Ocean, Australasia, and Brazil to the western Pacific Ocean.

한국의 자생해조 발굴연구의 과정에서 털가시우무(Hypnea flagelliformis Greville ex J. Agardh)가 동해 연안에서 채집되었다. 본 종은 뚜렷한 주축, 잘록한 기부의 가지, 주축 및 가지에 밀생하는 다수의 짧은 소지가 있으며, 수세포 벽에 원형질 비후가 없다는 점이 특징적이다. 털가시우무는 한국산 미기록종으로 본 연구에서 처음으로 보고된다.

In the course of survey of marine algal flora in Korea, a red algal species was collected from Pohang located in the eastern coast of Korea. This shares features of Hypnea, and is characterized by more or less percurrent axis and numerous and short branchlets densely covering axis and branches with basal constrictions, and absence of lenticular thickenings in medullary cell walls. In a phylogenetic tree based on rbcL sequences, this species nests in the same clade as Hypnea esperi. Genetic distance between this Korean entity and H. esperi was in intraspecific range as 0.6%. This alga is identified as Hypnea esperi based on the morphological and molecular data. This is the first record of H. esperi in Korea.
