Checklist of the cyanophytes/cyanobacteria and algae of the Slovak stretchof the Danube river (1926-1999)

The checklist contains all records of cyanophytes/cyanobacteria and algae f rom the Slovak stretch of the Danube river validly published during the yea rs of 1926-1999. 85 scientific contributions are compiled with nearly 4,000 records. Alltogether 282 genera with 1,050 species and infraspecific taxa have been found in the Slovak part of the Danube. This enumeration proceeds the first checklist of the Slovak Danube cyanophytes and algae (HINDAK & Z AHUMENSKY, 1983) in which 590 infrageneric taxa belonging to 191 genera wer e registered. During the period of 1981-1994 most taxa were confirmed again (123 genera with 273 infraspecific taxa), but 27 genera with 145 species, 17 varieties and 2 formas were recorded for the first time from this part o f the Danube (HINDAK, 1995).
