<i>Barranca variabilis</i> sp. nov.—A New Terrestrial Alga of the Genus <i>Barranca</i> (Chaetophorales, Chlorophyta) from the Baikal Region (Russia)
Filamentous green chaetophoralean algae are distributed mainly in aquatic ecosystems, less known from terrestrial habitats. Many of them have a complicated thalli and complex life cycles that make it difficult to determine these organisms by morphology. Description of new representatives of the Chae...

| description | Filamentous green chaetophoralean algae are distributed mainly in aquatic ecosystems, less known from terrestrial habitats. Many of them have a complicated thalli and complex life cycles that make it difficult to determine these organisms by morphology. Description of new representatives of the Chaetophorales continues. In this study, we have explored the filamentous green alga IRK–A 341 from soil of the Baikal Region by light and electron microscopy along with molecular phylogeny. Based on the results of morphological, ecological, and molecular phylogenetic analyses (18S–28S rDNA, <i>tufA</i>), we described the studied alga as the new species, <i>Barranca variabilis</i> sp. nov. The study complements the data on the diversity of soils green filamentous algae, and their biogeography. For the first time, the data on the structure of the cell walls and the cell ultrastructure of <i>Barranca</i> were established. The information on the morphology of the reproductive and resting cells is updated. |
