Summary: This study reveals a new species, G. khanjanapajiae, in Thailand through morphological and genetic analyses. The species can be distinguished by its dentate blade margin, deep spermatangial conceptacles, and abundant nutritive filaments. Phylogenetically, it is closely related to G. spinulosa from Taiwan. The research highlights the ongoing discovery of Gracilaria diversity and distribution in the tropical Indo-Pacific.

Summary: Molecular sequence analyses revealed that specimens previously identified as Cirrulicarpus sp. in southeastern Brazil are actually more closely related to the genus Meredithia. A new species, Meredithia dichotoma, is proposed to accommodate this rare and endemic taxon. It is characterized by its unique morphology and sequence divergence from its congeners. This finding represents the first record of a Meredithia species in Brazil and in the western South Atlantic, contributing to the diversity of the red algal family Kallymeniaceae.

Summary: In this study, the taxonomic identities of Meristotheca specimens from Korea and Japan were clarified using morphological and molecular data. A new species, Meristotheca pilulaora sp. nov., was identified in Korea, and Meristotheca japonica was rediscovered in Japan. These findings contribute to our understanding of species diversity in the genus Meristotheca and have implications for conservation, management, and selection of haplotypes for future cultivation of these economically important species.

Summary: A new seaweed, Pseudobangia corderoi, previously misidentified as Bangia fuscopurpurea, was described from the Philippines. Molecular analysis showed that P. corderoi is closely related to an unidentified Pseudobangia species from Taiwan, and they are the closest relatives to Pseudobangia kaycoleae. Phylogenetic studies also confirmed the monophyly of Pseudobangia and its sister relationship with the 'Bangia 2' lineage. Morpho-anatomical analysis only found one distinguishing character, larger thallus dimensions, for P. corderoi compared to other filamentous Bangiales.

Summary: Recent segregation of 12 genera in the tribe Streblocladieae has updated the taxonomy of certain species belonging to Polysiphonia sensu lato, with new combinations being proposed. Six new additions to the tribe have been made based on morphological and molecular analyses, including the description of a new species and proposal of new combinations. The study also identified additional diagnostic features for two genera within the tribe, providing insights into distribution, diagnostic features for delimiting genera morphologically, and molecular evolutionary relationships.

Summary: A multigene molecular phylogeny was conducted to study the genus Phymatolithon. The study revealed the polyphyletic grouping of two monophyletic clades within the Hapalidiales. As a result, a new genus, Phymatolithopsis, was established, consisting of three species. Phymatolithopsis is closely related to Mesophyllum and is distinct from Phymatolithon and boreal species assigned to Lithothamnion. Morpho-anatomical characteristics were used to differentiate Phymatolithopsis from Phymatolithon, including the origin of conceptacle primordia and the distribution of gonimoblast filaments in carposporangial conceptacles.

Summary: The coralline algal genus Corallinapetra is monospecific and distinct from other families and orders within the Corallinophycidae. DNA analysis supports the establishment of a new family and order for Corallinapetra, and the reassignment of L. gabrielii to Corallinapetra. Additionally, comparison of molecular data confirms the placement of L. muelleri within the Hapalidiales.

Summary: Molecular techniques have revealed two cryptic clades within the temperate red alga Asparagopsis armata, originating from Australia and New Zealand. Haplotype variation has been identified within each clade, with different distributions in Australia, Europe, South Africa, and New Zealand. Further research is needed to explore the differences in morphology, physiology, and biochemistry of genetically distinct mitochondrial lineages within each clade.

Summary: This study used DNA-based species identifications to explore the composition of coralline algal communities and examined the environmental variables that drive community structure along the New Zealand coastline. The research found that sea surface temperature and light were significant factors affecting the composition of coralline algal communities, while wave exposure and turbidity had less influence.

Summary: Phylogenetic analyses revealed that the specimens previously identified as Sonderophycus coriaceus from Manawatawhi/Three Kings Islands actually belong to the genus Agissea, and were named as Agissea teruruhau. A new red algal epiphyte species, Piriora waewaiti, was discovered on Agissea teruruhau. These findings have increased the reported endemic algal flora of the Manawatawhi/Three Kings Islands and confirmed the presence of Olokunia boudouresquei and three other species of Peyssonneliales in the New Zealand flora.

Summary: DNA sequencing was used to study the taxonomy of two Australian red algal species, one of which was found to be identical to the European Aphanocladia stichidiosa. However, it was unexpectedly classified in the Lophurella genus rather than Aphanocladia. Another Australian species was described as L. pseudocorticata sp. nov. The study highlights the importance of using phylogenetic approaches to identify and determine the native ranges of introduced species.

Summary: This study assesses the calcification physiology of five cool temperate coralline algae in response to different irradiance levels and finds that the enhancement of calcification rates is limited to lower irradiances. The study also suggests the existence of two calcification strategies and indicates that magnesium incorporation is determined by the magnesium to calcium ratio in the calcifying fluid.

Summary: The carrageenophyte red alga Sarcothalia radula (previously known as Gigartina radula) is a safe source of carrageenan hydrocolloid and a food additive, as well as a potential source of compounds for various commercial applications. However, the type material and type locality of the species has been unclear. This study discusses the possible collection location and argues that it was collected during Captain Cook's second voyage to southern New Zealand. The study also designates a lectotype and an epitype.

Summary: Accurate species identification is crucial for biological studies. This study investigated the species identification and distribution of G. filicina-like species in the Northwest Pacific using rbcL sequences. The results revealed the most common species in the region is G. asiatica, and highlighted the need for reevaluating the identification of G. dalianensis, G. serra, and G. variata.

Summary: This study explores the diversity and identification of crustose coralline algae (CCA) using different preservation methods and molecular biology techniques. The results show that CCA has immense diversity, with higher diversity in the inner layers compared to the outer layers. Among the molecular markers tested, the 23S rRNA and rbcL genes are more suitable for identifying algae, while the cox1 gene captures a broader range of diversity, including algae.

Summary: The impacts of global climate change on New Zealand's seaweed ecosystems, including increasing marine heatwaves, coastal darkening, and ocean acidification, have been observed. These impacts have already led to negative effects on canopy forming brown algae and are predicted to cause poleward range shifts and reduced growth rates of seaweed species. The interaction between global climate change and local stressors, such as overfishing, will determine the future of New Zealand's seaweed ecosystems.

Summary: To resolve the uncertainty around taxonomic classification of Sporolithon species, targeted PCR sequencing was conducted on historical and recently collected specimens. The results confirmed the existence of distinct species and identified previously misclassified specimens. DNA sequencing of type specimens of coralline species was shown to be the most reliable method for accurate naming.
