We have gathered samples of plants that were showing signs of infection with rust fungi (Pucciniales) in University Botanical Gardens Ljubljana. We have then analyzed these samples with microscope in Slovenian Forestry Institute's laboratory. We have identified 14 species of rust fungi using literature: Coleosporium inulae on host plant Inula magnifica, Cronartium flaccidum on host plant Vincetoxicum medium, Phragmidium potentillae on host plant Potentilla alba, Phragmidium mucronatum on host plant Rosa virginiana, Puccinia crepidis on host plant Crepis foetida, Puccinia urticae-pilose on host plant Carex pilosa, Gymnosporangium sabinae on host plant Pyrus nivalis, Uromyces striatus on host plant Medicago pironae, Puccinia iridis on host plant Iris sibirica, Puccinia lapsanae on host plant Lapsana communis, Puccinia convolvuli on host plant Calystegia sepium, Puccinia behenis on host plant Silene spp., Leucotelium cerasi on host plants Prunus tenella and Eranthis hyemalis and Pucciniastrum agrimonae on host plant Agrimonia procera. We have made a herbarium and imported the data in the fungi database Boletus informaticus. We have compared identified species with the findings of Wilhelm Voss, who wrote the book Mycologia Carniolica, which contains all the fungi he found in the Slovenian territory. The results show that almost half of the fungi we identified were not yet found in Slovenia by W. Voss, likely due to lack of researches. However, all of them were found in Austria and Switzerland.
