Oxynema, a new genus separated from the genus Phormidium (Cyanophyta)
Original language description
Taxonomic revision of the traditional polyphyletic cyanobacterial genus Phormidium is based on molecular sequencing combined with the definition of distinct, autapomorphic features. Several genera, clearly separated from each other (with genetic similarity lower than 95%), were already defined and separated from this widely conceived generic unit (Phormidesmis. Wilmottia and others). All of these new generic taxa are characterized by morphological markers also. We have studied another group of species (mainly the strains from salterns in Thailand), which was classified earlier in the genus Phormidium, but it represents an isolated cluster according to 16S rRNA gene sequencing and is characterized by specific uniform and morphological features. Becausethis whole group represents a phylogenetically and morphologically distinctly separated cluster (see Phormidium group I sensu Komarek & Anagnostidis 2005), we describe it as a special taxon Oxynema genus novum, in agreement with the Botan
