Geitleribactron—a newChamaesiphon-like blue-green alga


In the littoral of the lakes Titisee (FRG) and Neusiedler See (Austria) and in a backwater near Stockerau (Austria) two periphytic unicellular blue-green algae with rod-like cells have been found. They were formerly thought to be members of the exosporine generaChamaesiphon orCyanophanon. Now the alga from Titisee was studied in culture, particularly with reference to cell division, reproduction and ultrastructural cytology. Similarities with the genusSynechococcus are evident, but there is a small mucilaginous disc at the basis of the cells. Because of differences between this and all other known genera of unicellular blue-green algae, a new genus,Geitleribactron, with two species,G. periphyticum (= type species) andG. subaequale, is described.
