Fusarium species from section Discolor are widespread and well-known and play an important role in disease etiology of wheat, barley and maize. F. graminearum and F. culmorum were isolated during a four-year period at several locations in Eastern Croatia and from different hosts. The mycelium development of 236isolates of F. graminearum and 2 isolates of F. culmorum was cultered during an eight day period on water agar, PDA, Bilai, Czapek's and CLA agar at temperatures 5°, 15°, 20°, 25° and 30°C and a 12 hour dark/light regime. The results show that agar medium does not influence colony diameter significantly. The agar medium influences the richness and density of the aerial mycelium significantly, although the shape and compactness of the mycelium is not only the result of the medium on which the fungus is developed, but also of the characteristics of the species itself. The sporulation of F. culmorum was abundant on all investigated medium, whereas the sporulation of F. graminearum was very weak on PDA and Bilai agar and it was medium on CLA.
