Occurrence
The yellow tooth rust occurs in Europe and North Africa (subsp. Reboudii ). It grows on patchy xerothermal lawns , in the edges of dry forests and bushes. It prefers moderately dry, mostly chalky, nutrient-poor clay, loess or gypsum soil in warm locations. In Central Europe it is a species of the Festuco-Brometea class, but also occurs in societies of the Sedo-Scleranthetea class.
In Austria, the yellow tooth rust occurs scattered in the Pannonian area and rarely on dry grass in the rest of the area. The occurrences extend to the federal states of Vienna , Lower Austria , Burgenland , Styria , Carinthia and North Tyrol .
