Hydrurus foetidus (Vill.) Trev. is one of the few macroscopic freshwater golden algae (Class Chrysophyceae) - and, contrary to most other sessile freshwater algae, it prefers winter conditions in rivers and brooks where temperature is near to 0° C. During the first months of spring, it may bloom and cover the bottom where turbulence is high and light conditions are best. At Finse, the Garpefoss out of lake Finsevatn is a locus classicus - studied by Strøm for his doctoral dissertation (see Strøm 1926), and where Hydrurus still occurs regularly from end of February through the spring months.
