Gloeocapsopsis aurea, a new subaerophytic cyanobacterium from maritime Antarctica

The cyanobacterial flora of maritime Antarctica appears to contain many endemic species and only few cosmopolitan or wider-distributed taxa. Several morphospecies that have been erroneously identified in the past following available keys from temperate or tropical zones belong in fact to little-know...
