Summary: Two green microalgal strains, CCCryo 469-16 and CCCryo 470-16, were isolated from Antarctic microflora samples. Through morphology and 18S rRNA sequence analysis, they were found to be phylogenetically related to strains of Chlorococcum, Macrochloris, and Pleurastrum genera. The study utilized molecular markers to re-establish the reference strain and define the molecular borders of Pleurastrum and Chlorococcum genera. Based on the findings, several Chlorococcum species were re-attributed to Pleurastrum and a new combination was proposed for Macrochloris rubrioleum. Additionally, a relationship between Pleurastrum lineages and climate zones was established.

Summary: This study assessed different perspectives to establish a stable taxonomic framework for Ulva green seaweed, finding that species delimitation methods using the tufA gene were the most consistent. DNA-based species delimitation often disagreed with traditional morphology-based definitions, and biological species concepts were generally narrower than DNA-based delimitation. Although molecular markers improved our understanding of Ulva diversity, names associated with DNA sequences in public databases are unreliable, highlighting the need for further research in tropical regions.

Summary: This study isolated and identified 15 Dunaliella strains from active and abandoned saltworks in Greece, which were classified into nine species based on morphological features. The phylogenetic analysis revealed distinct clades among different Dunaliella species, indicating that morphological features may not always align with phylogenetic relationships. The strains produced a low amount of beta-carotene under laboratory conditions. This study provides valuable information on the diversity of Dunaliella strains in Greek saltworks and highlights the need for further molecular data on Dunaliella spp.

Summary: This study presents the results of morphological and phylogenetic analysis of Coleochlamys apoda strain ACSSI 377, isolated from a biological soil crust in the North of Russia. The study reports the presence of mature S-shaped cells and the formation of synzoospores for the first time in this species. Molecular genetic analysis confirmed the strain's belonging to the species Coleochlamys apoda. The study also analyzed the ecology and distribution of Coleochlamys and its sister genus Microthamnion.

Summary: The study investigated the taxonomy of Cephaleuros in southern China and identified eight morphospecies. Molecular phylogeny analyses revealed two main lineages within Cephaleuros, with one lineage mostly comprising samples of C. karstenii and C. virescens. The study highlights the importance of using molecular markers in addition to morphological features for accurate identification of Cephaleuros.

Summary: Despite the large number of publications about Chlorella-like algae, their identification remains challenging due to their simplicity and ability to change their appearance. This study uses molecular techniques to understand the diversity of these algae and proposes a new genus, Neochlorella, with IPPAS C-1210 as the type species. Additionally, the study reassigns the strain C. thermophila ITBB HTA 1-65 to this new genus. The study also discusses the unique ultrastructural and physiological traits of the new species.

Summary: This study confirmed that the green algal genus Oncosaccus, endemic to China, actually belongs to the order Chaetopeltidales instead of Chlamydomondales, based on molecular data and ultrastructure analysis. The morphological features of Oncosaccus tetrasporoides were found to be similar to Chaetopeltis and Pseudulvella, supporting its placement within the Chaetopeltidales.

Summary: A new red alga species, Dasya japonovillosa, is introduced from Japan. This species, as well as D. enomotoi, were previously misidentified as D. villosa by researchers in Japan due to their elongated axes densely covered with soft monosiphonous filaments. Dasya villosa can be distinguished from D. japonovillosa and D. enomotoi by the presence of five pericentral cells in transverse sections and palisade-like tetrasporangial cover cells. The unique characteristics of the new species include elongated axis (up to 65 cm), subdichotomously divided axes and polysiphonous branches, indistinct pericentral cells in transverse sections except near the apices, enlarged inner cortical cells, radially arranged numerous soft monosiphonous filaments, three-celled carpogonial branches, four tetrasporangia in each fertile segment of the stichidia, and one (rarely two) tetrasporangial cover cell that is not elongated longitudinally and rarely divided transversely.

Summary: Limited information on parasitic infections of Carangoides fulvoguttatus prompted a study to investigate the gill parasite Heteromicrocotyla polyorchis, providing a full morphological description and clarifying its taxonomic status through phylogenetic analysis. Specimens were collected from the Red Sea in Saudi Arabia, where the unique genetic sequences of the isolated Heteromicrocotyla species were analyzed and deposited for the first time in GenBank. Phylogenetic analyses revealed a well-distinct clade for this monogenean species, supporting its classification within the Heteromicrocotylidae family.

Summary: This study reports a novel hypotrich ciliate, Histriculus tolerans n. sp., isolated from a water sample collected from an industrially contaminated outlet in Onsan, Ulsan, South Korea. The new species is characterized by a small cell size, elongate ellipsoidal macronuclear nodules, and adoral zone with membranelles. Phylogenetic analyses consistently place the new species within the family Oxytrichidae, clustering with H. histrio.

Summary: We present a new method for efficiently sampling Chlamydomonas reinhardtii and closely related species using colony PCR-based screen and novel primer sets designed for specific detection. We collected 130 soil samples from various habitats in Ontario, Canada, and identified 33 candidate algae, which were analyzed using rbcL plastid gene sequencing, 18S rRNA gene sequencing, and YPT4 nuclear marker sequencing. Phylogenetic and haplotype network analyses revealed seven novel isolates of C. reinhardtii and one closely related species. The molecular screen was validated by demonstrating the ability of the seven new C. reinhardtii strains to freely interbreed with previously collected field isolates.

Summary: The study investigated the composition, abundance, and environmental drivers of cyanobacterial biocrust in two important biomes in Brazil, Caatinga and Pampa, revealing distinct taxonomic compositions and assemblages at each biome. Soil temperature and pH were identified as the main factors explaining the differences in biotic structures. The findings are expected to enhance biocrust conservation efforts and promote the use of biocrust cyanobacteria as indicators of global change.
