Fungi are associated with the European cranberry (Vaccinium oxycoccos L.) and play important roles in plant growth and disease control, especially in cranberry yields. This article presents the results of a study which was aimed to investigate the diversity of fungi found on different clones and cultivars of the European cranberry grown in Lithuania, causing twigs, leaf diseases and fruit rots. In this study seventeen clones and five cultivars of V. oxycoccos were selected for investigation. Fungi were isolated via the incubation of twigs, leaves and fruit on a PDA medium and identified according to their cultural and morphological characteristics. Microscopic fungi belonging to 14 genera were isolated from cranberry leaves and twigs, with Physalospora vaccinii, Fusarium spp., Mycosphaerella nigromaculans and Monilinia oxycocci being the most frequently isolated fungi. &lsquo:Vaiva&rsquo: and &lsquo:Ž:uvinta&rsquo: cultivars were the most susceptible to pathogenic fungi during the growing season. Among the clones, 95&ndash:A&ndash:07 was the most susceptible to Phys. vaccinii, 95&ndash:A&ndash:08 to M. nigromaculans, 99&ndash:Ž:&ndash:05 to Fusarium spp. and 95&ndash:A&ndash:03 to M. oxycocci. Microscopic fungi belonging to 12 genera were isolated from cranberry berries. The most prevalent pathogenic fungi M. oxycocci were isolated from the berries of the cultivars &lsquo:Vaiva&rsquo: and &lsquo:Ž:uvinta&rsquo: and clones 95&ndash:A&ndash:03 and 96&ndash:K&ndash:05.
