Nomenclatural changes in cyanoprokaryotic order Oscillatoriales

The taxonomic criteria in Cyanoprokaryotes (cyanophytes = cyanobacteria)were changed considerably in last decades, respecting numerous new dataderived mainly from modern electron-microscopic, ecological and molecularstudies. The substantial revision of the cyanobacterial system was thereforenecessary, and all names of revised taxa should be corrected in agreementwith nomenclatural rules before the edition of all new monographs and manualsconcerning this important group. The content of the present article isthe correct and valid publication of nomenclatural transfers of specificand generic names for the second volume of Cyanoprokaryotes in the frameof the Süsswasserflora von Mitteleuropa (19/2, order Oscillatoriales),which is now prepared for press. The paper (including Appendix 1 by J.Komárek) contains 208 nomenclatural combinations, 17 new species, and descriptionof 2 new genera of oscillatorialean cyanobacteria, as a result of a modernrevision of the whole order. The species are arranged according to therecent phenotype system of cyanoprokaryotes (Cyanobacteria).
