“…How often branched Cladophora ‐like body plans and unbranched morphologies evolved independently in this order remains poorly understood and therefore several genera remain polyphyletic despite recent efforts to make progress in understanding their evolutionary history and adapting the taxonomy (Leliaert et al. ,b,c, , Boedeker et al. , Ichihara et al.…”

The taxonomy of the Cladophoraceae, a large family of filamentous green algae, has been problematic for a long time due to morphological simplicity, parallel evolution, phenotypic plasticity, and unknown distribution ranges. Partial large subunit (LSU) rDNA sequences were generated for 362 isolates, and the analyses of a concatenated dataset consisting of unique LSU and small subunit (SSU) rDNA sequences of 95 specimens greatly clarified the phylogeny of the Cladophoraceae. The phylogenetic reconstructions showed that the three currently accepted genera Chaetomorpha, Cladophora, and Rhizoclonium are polyphyletic. The backbone of the phylogeny is robust and the relationships of the main lineages were inferred with high support, only the phylogenetic position of both Chaetomorpha melagonium and Cladophora rupestris could not be inferred unambiguously. There have been at least three independent switches between branched and unbranched morphologies within the Cladophoraceae. Freshwater environments have been colonized twice independently, namely by the freshwater Cladophora species as well as by several lineages of the Rhizoclonium riparium clade. In an effort to establish monophyletic genera, the genera Acrocladus and Willeella are resurrected and two new genera are described: Pseudorhizoclonium and Lurbica.

“…Even more remarkably, the same is true for different phenotypes within a single species, as illustrated in Figure 4g–j. Cryptic diversity, parallel evolution, and intraspecific morphological variation have been well documented in the Cladophorales (e.g., Boedeker et al, 2018; Leliaert, Payo, et al, 2011; Leliaert, Verbruggen, et al, 2009). Unbranched filaments have evolved independently at least seven times in the Cladophorales, and Rhizoclonium ‐like morphologies at least five times (see Boedeker et al, 2012, 2016, 2018; Hanyuda et al, 2002; this study).…”

The continental coasts and remote islands in the high‐latitude Southern Hemisphere, including the subantarctic region, are characterized by many endemic species, high abundance of taxa, and intermediate levels of biodiversity. The macroalgal flora of these locations has received relatively little attention. Filamentous green algae are prolific in the intertidal of southern islands, but the taxonomy, distribution, and evolutionary history of these taxa are yet to be fully explored, mostly due to the difficulty of access to some of these locations. In this study, we examined specimens of the order Cladophorales from various locations in the high‐latitude Southern Hemisphere including the subantarctic (the Auckland Islands, Bounty Islands, Campbell Island, Macquarie Island, and Kerguelen Islands), as well as mainland New Zealand, the Chatham Islands, Chile, and Tasmania. The analyses of the rDNA sequences of the samples revealed the existence of two new clades in a phylogeny of the Cladophoraceae. One of these clades is described as the novel genus Vandenhoekia gen. nov., which contains three species that are branched or unbranched. The amended genus Rama is reinstated to accommodate the other clade, and contains four species, including the Northern Hemisphere “Cladophora rupestris.” In Rama both branched and unbranched morphologies are found. It is remarkable that gross morphology is not a predictor for generic affiliations in these algae. This study illustrates that much can still be learned about diversity in the Cladophorales and highlights the importance of new collections, especially in novel locations.

“…In the single specimen we found, it was not possible to observe the basal portion of the plant, which is an important character to distinguish among the Ulothrix species present in the Caribbean flora. However, we consider this alga to be a member of the genus Ulothrix because of its diminutive habit, and the presence of just one chloroplast per cell (the genus Chaetomorpha has several, with the exception of C. philippinensis, Leliaert et al, 2011) (Figure 4b). The genus Uronema is composed of diminutive species, mostly restricted to freshwater habitat.…”

Nine species of macroalgae are newly reported for the Caribbean International Biosphere Reserve Seaflwer. Of these taxa, Neosiphonia sphaerocarpa, Polysiphonia schneideri, Polysiphonia sertularioides, Cladosiphon occidentalis, and Phaeophila dendroides, have been previously reported from Colombian waters, whereas Ulothrix sp., Ulva flxuosa subsp. paradoxa, Chaetomorpha minima, and Cladophora liniformis represent new records for the country. All the algae were found growing epiphytically on Thalassia testudinum in shallow (<1 m) seagrass meadows around San Andrés Island. Their morphological features are discussed.
