Ceratocystiopsis spp. associated with pine- and spruce-infesting bark beetles in Norway

Abstract The genus Ceratocystiopsis ( Ophiostomatales , Ascomycota ) includes 21 species, which can be found mainly in association with bark beetles the Northern Hemisphere. A survey of species associated infesting Picea abies and Pinus sylvestris Norway yielded 126 isolates, representing neglecta rollhanseniana four described herein as chalcographii debeeria norroenii troendelagii . new taxa were morphologically characterised phylogenetically analysed on basis sequence data multiple loci (ITS, LSU, beta-tubulin TUB2 ), calmodulin CAL translation elongation factor 1-alpha TEF1 genes). C most frequently isolated latter had wider vector range.
