Oak decline presenting symptoms of tracheomycosis have been observed globally over long periods time. Since the 1990s, oak has considered to be a multifactorial process where abiotic predisposing factors play significant role. Nevertheless, biotic factors, such as subcortical insects and fungal pathogens, may influence process, some insect species transmit spores tracheomycotic pathogens. We in...

Ophiostomatoid fungi were isolated from Scolytus ratzeburgi infesting Betula pendula and B. pubescens in Norway. Fungi were identified based on morphology, DNA sequence comparison for two gene regions and phylogenetic analyses. The most abundant fungus was Ophiostoma karelicum, suggesting a specific relationship between the fungus, the vector insect and the host tree. Our results suggest that O...

Entomochoric spore dispersal is well-documented for most ophiostomatoid fungal genera, most of which are associated with bark or ambrosia beetles. Gondwanamyces spp. are unusual members of this group that were first discovered in the flower heads of the primitive angiosperm genus Protea, that is mostly restricted to the Cape Floristic region of Africa. In this study, we present the discovery of...
