Abstract:Certain related oscillatorialean species, originally attributed to the genusOscillatoria and recently assigned to subg.Geitlerinema of the genusPhormidium (Phormidiaceae-Phormidioideae), are revised and reclassified. Based on a reevaluation of the diacritical features, subg.Geitlerinema is raised to generic rank and assigned to the familyPseudanabaenaceae (tentatively to subfam.Pseudanabaenoideae). The individual species are reviewed and the necessary new combinations are made.Dedicated to Prof. DrLothar Geitler on the occasion of his 90th birthday.
Keywords:Cyanophyta  Oscillatoriales  Phormidiaceae  Pseudanabaenaceae  Geitlerinema stat. nov.  Oscillatoria  Phormidium  Jaaginema  Taxonomy  morphology  ultrastructure
