Summary: This study conducted molecular, genetic, and morphological analyses of Lomentariaceae, resulting in the discovery of a new species, Ceratodictyon sanctae-crucis sp. nov., and the proposal of a new genus, Yendoa gen. nov., within Lomentariaceae. The study also revealed that Lomentariaceae now consists only of monophyletic genera, providing a more coherent taxonomic framework for the family.

Summary: We analyzed sequence data of rbcL and COI in Schizymenia specimens from the Sea of Okhotsk and Sea of Japan. A new species, S. tamarae sp. nov., was discovered in the northwestern Sea of Japan. Morphological and genetic analyses confirmed that the previously described S. jonssonii is a synonym of S. dubyi var. palmata, which was originally described from the Kuril Islands. The taxon was synonymized with Neoabbottiella valentinae. We propose renaming it as Schizymenia valentinae comb. nov. The known Schizymenia species along the Russian coast are S. valentinae and S. tamarae.

Summary: DNA sequence analysis reveals that the current classification of Gelidium is not monophyletic, with three distinctive lineages. A new genus, Gelidiorariphycus, is described to accommodate one of these lineages. The species in this genus have similar morphologies and primarily grow on shallow subtidal rocky shores.

Summary: This study describes two new species, Endoplura jejuensis and E. koreana, from Korea based on molecular and morphological analyses. Phylogenetic analysis shows that they are closely related to E. aurea from Japan. E. jejuensis is characterized by small light to dark brown thalli, while E. koreana has larger olive or yellowish-brown thalli.

Summary: The study evaluated the efficiency of four genetic markers in barcoding diatoms isolated from China, showing that multiple genetic markers can clearly differentiate most species and reveal potential cryptic species. COI, rbcL, and LSU sequences demonstrated high taxonomic resolution at the species level, while potential identification errors were found in public diatom sequences. Phylogenetic and character-based analysis provided consistent species identification and clearer species discrimination compared to the distance-based method.

Summary: This study used DNA sequences and morphological observations to confirm that Cystoclonium obtusangulum actually consists of two distinct species, leading to the proposal of a new genus name Meridionella. These two species are morphologically similar but have different distributions, one found in South America and the Falkland Islands, and the other occurring in Antarctic waters.

Summary: This case report describes a gastrointestinal basidiobolomycosis (GIB) caused by a novel Basidiobolus omanensis species in a 20-year-old male patient. The isolate showed high minimum inhibitory concentrations (MICs) to multiple antifungal drugs but low sensitivity to amphotericin B. Molecular identification is crucial for rare opportunistic fungi.

Summary: The taxonomy of the genus Gonyaulax is challenging due to the conservative morphology of its thecate structure. However, cysts of Gonyaulax show variations in morphology and are related to fossil-based genera Spiniferites and Impagidinium. Through germination experiments, new species of Gonyaulax were identified and a well-resolved clade based on molecular phylogeny was formed. Additionally, low concentrations of yessotoxin were detected in one G. bohaiensis strain.

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: The study revealed that the red algal genus Devaleraea, specifically the species D. stenogona, displays complex morphological differences over its geographic range, splitting into two congeneric species. The newly proposed species D. titlyanova sp. nov. is characterized by abundant proliferations larger than the main blade, with distinct morphological differences compared to D. stenogona. Additionally, the two species have different geographical distributions, with D. stenogona occurring further south than D. titlyanova.

Summary: Partial rbcL sequences were analyzed from type specimens of three early-described Corallina species. The results revealed that C. arbuscula and C. pilulifera are synonymous, with C. pilulifera being the accepted name, and that C. vancouveriensis is a distinct species. Additional species, C. hakodatensis sp. nov. and C. parva sp. nov., were also identified. These findings have important implications for the biogeography, evolution, and speciation patterns of coralline algae.

Summary: This study used morphological and molecular phylogenetics methods to study turf-forming species of the genus Pterocladiella in southern China. A new species and a previously unrecorded species were identified, and additional descriptions of reproductive structures were provided for two other species. This study enhances our understanding of the biodiversity of Pterocladiella in China and reveals the potential diversity of small turf-forming species in tropical coral reefs.

Summary: This study identified 11 independent genetic lineages of Ralfsia-like taxa, leading to the proposal of a new classification unit, Pseudoralfsiaceae, and two new genera, Pseudoralfsia and Nuchella. Additionally, species of Pseudoralfsiaceae can be distinguished from Ralfsia sensu stricto (Ralfsiaceae) mainly by DNA sequences and by consistently having frequent hair pits, and typically unsymmetrical thalli.

Summary: Specimens of Spyridia 'filamentosa' from Southern New England and New York were sequenced for mitochondrial COI-5P and chloroplastic rbcL genes, showing distinct differences from Mediterranean specimens. As a result, a little-known species name, Spyridia americana Durant, was assigned to specimens collected from the northeastern coast of the United States.

Summary: Partial rbcL sequences were obtained from type specimens of Lithophyllum coarctatum and L. gardineri. Despite morpho-anatomical similarities, phylogenetic analyses confirmed that both species belong in Porolithon. A novel epiphytic species, P. epiphyticum sp. nov., from Cocos-Keeling Islands was also identified.

Summary: Molecular analyses have revealed discrepancies in Australian taxa previously classified as Plocamium cartilagineum with the species from its northern hemisphere type locality. After examining and designating a lectotype for Plocamium pusillum, it has been resurrected as a distinct species genetically and morphologically, differing from authentic P. cartilagineum.

Summary: In the last decade, molecular tools have revealed previously unrecognized taxa in Bermuda's marine flora, especially among the Rhodophyta. Misidentified species have been reclassified and many novel species have been discovered. The `Laurencia complex' has also been modified globally, with five of the eight recognized genera found in Bermuda. The study presents new species and revises the classification of existing ones using genetic sequencing.

Summary: By screening DNA from 285 coralline crusts in Canada and adjacent waters, the distribution range of Porphyra corallicola was found to be far beyond previous knowledge. In addition, it was found that other species also exist only in the Conchocelis stage. The further development of this method will facilitate the study of Conchocelis stages in nature, greatly enhancing ecological knowledge of bangialean species.

Summary: The Acrotylaceae, a red-algal family composed of six genera, lacks common habits and vegetative features among them, with cystocarps being the most unifying characteristic. Molecular studies reveal that the family consists of two subfamilies, Acrotylaceae and the newly proposed Clavicloniaceae. The South African genus Reinboldia, previously included in Acrotylaceae, is now considered questionable for inclusion in the family.
