Abstract

Asexual ascomycetes were isolated from Polygraphuspolygraphusor Hylurgopspalliatus (Coleoptera: Scolytidae) (NISK-93-208/44 and NISK-94-166/39, respectively) in a Norway spruce (Picea abies) forest. Although the two fungal isolates are distinct in appearance and display specificity to different hosts, the isolates are genetically identical in the nu- clear encoded small subunit, large subunit, and internal transcribed spacer rRNA gene regions that we sequenced. Phylogenetic analyses and observations based on DNA placed the Norwegian isolates in an Ophiostomaclade. Within the clade the isolates occurred in a subclade with 0. ulmi and 0. piliferum and several Ambrosiellaspecies (A. macrocarpa, A. tingens, and A. ips). A second subclade contained additional species of Ophiostomaand Ambrosiella.The beetle vectors of the fungi have different flight times and host tree usage, suggesting that their behavior helps to isolate the fungi in time and space.
