N2 - This study investigated the wood colonization by rot, blue stain or discoloration causing fungi, focusing on the quality of roundwood assortments of several economically important tree species in Latvia. A total of 105 trees were analysed across Latvia, including Pinus sylvestris (34), Picea abies (22), Betula pendula (10), Alnus glutinosa (29), and Populus tremula (10). Trees were randomly selected during or after felling based on visible signs of fungal infection: wounds, blue stain, wood discolouration, stem rot, cracks, and other symptoms. Wood-inhabiting fungi were isolated from different zones of one disc per tree (340 wood samples in total). Fungi were identified based on their morphological characteristics and molecular analysis (ITS region sequencing with primers ITS4 and ITS1F). A total of 56 fungal taxa were isolated from the wood samples. Among the rot-causing fungi, Heterobasidion spp. was frequently isolated from conifers; Porodaedalea pini and Stereum sanguinolentum were isolated specifically from pine and Amylostereum areolatum-from spruce. Xanthoporia radiata and Eutypella cerviculata were frequently isolated from black alder; while-Phellinus tremulae-from aspen wood. The blue stain causing fungi Ophiostoma spp. were isolated from pine, spruce and birch wood, while Diplodia spp. – only from spruce. This work was funded by JSC Latviaʼs State Forests (project No. 5-5.5.1_0009_200_24_7) and Forest4LV (project No. VPP-ZM-VRIIILA-2024/2-0002).
