For the purpose of the present study, algae were investigated in two eutrophic lakes, two peat bogs, three different waterfalls, four different springs, a brackish lake, three types of wastewater, four types of aerial habitat, and the flysch river of Dragonja, all in Slovenia. The study was carried out in the environments in Slovenia that have been only partly or never investigated before. Samples were taken seasonally at 26 sampling sites from 1998 to 2001. There were altogether 537 algal taxa registered, with prevailing occurrences of Bacillariophyceae (295 taxa). Of the identified taxa, 146 were recorded for the first time in Slovenia, 107 of which belong to Bacillariophyceae, 28 to Cyanophyceae, 6 to Chlorophyceae, 4 to Zygnematophyceae and 1 to Xanthophyceae. The occurrence of almost half of all algal taxa was limited to individual sampling sites. Achnanthes minutissima, Cymbella affinis, C. silesiaca, Gomphonema angustum, Navicula veneta, and Trentepohlia aurea were the most widespread species.
