    Description: 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. karelicum occurs across the geographic range of S. ratzeburgi and its close relatedness to the Dutch elm disease fungi suggests that it could be important if introduced into other parts of the world. Other fungi, only occasionally isolated from S. ratzeburgi, were identified as O. quercus and a novel taxon, described here as O. denticiliatum sp. nov.

    Ophiostoma spp. associated with pine- and spruce-infesting bark beetles in Finland and Russia (2010)
    In:  Persoonia - Molecular Phylogeny and Evolution of Fungi vol. 25 no. 1, pp. 61-71

    Description: Baobabs (Adansonia spp.) are iconic trees, known for their immense size, strange forms, sources of food and as the subjects of myths and mysteries. It is thus surprising that little is known regarding the fungi that infect these trees. During a survey to determine which wound infecting fungi occur on baobabs, synnematous structures were observed and Graphium-like isolates were obtained. Culture characteristics and micro-morphology, together with DNA sequence comparisons for the SSU rRNA, rRNA-ITS and TEF-1\xce\xb1 gene regions were used to characterise these fungi. These data revealed three novel Graphium spp. and these are described as G. adansoniae, G. madagascariense and G. fabiforme.
