The ophiostomatoid fungi associated with cerambycid beetles Tetropium spp. (their symbiotic vectors) colonizing Norway spruce in Poland (six species collected) were isolated. The virulence of representative isolates was evaluated through inoculations using 2-year-old Norway spruce seedlings. A total of 1325 isolates (Ophiostoma piceae, O. tetropii, O. minus, Grosmannia piceiperda, G. cucullata, and five other less frequent taxa) were obtained. Tetropium castaneum and T. fuscum were vectors of similar spectra of ophiostomatoid fungi although some differences in fungal frequency between these Tetropium spp. were found. Among the fungal associates of the Tetropium spp. collected only G. piceiperda was pathogenic, which suggests that it can play a role in the death of spruce trees following attack by Tetropium spp
