THE MOST IMPORTANT FUNGI ON WYCH ELM (ULMUS GLABRA) TREES IN MONTENEGRO

In summary, early researches about fungal diversity on wych elm (Ulmus glabra) were rare, and besides Saccardo (1898) none of above literature sources precisely described the diversity of fungi on specific tree species from genus Ulmus. Practical application of these results on global scale is to avoid production of plant material tolerant to Dutch elm disease but susceptible to other fungal pathogens. On wych elm (Ulmus glabra) trees, 21 fungal species was found, where by 1 fungal species was found on rot, 2 fungal species were found on leaves, 18 species were found on trunk and 3 species were found simultaneously on trunk and fallen branches (Table 1). The most important species are Ophiostoma novo-ulmi and heart rot fungi. Besides Ophiostoma novo-ulmi sa the most important pathogen, heart rot fungi were major pathogens on older trees that avoided Dutch elm disease (Table 1).
