Cyanobacteria are crucial components of biological soil crusts of polar landscapes and carry out many functions in subaerial environments. Simple untapered filamentous cyanobacteria are typically in the terrestrial biotopes. They appear to be a group with an abundance of cryptic taxa. We isolated 23 strains of cyanobacteria from the different habit...
