Abstract
Spores characteristic of the tree pathogenic blue-stain fungus, Ophiostoma polonicum Siemasko, and other fungi are visible in scanning electron micrographs of pits on the pronotum and elytra of Ips typographus (L.). Inoculation and reisolation experiments show that O. polonicum was transmitted to logs at generally higher frequencies by live beetles and their excised parts (head, prothorax, or elytra) than by the digestive tract. Other associated fungi isolated at high frequencies from I. typographus were O. bicolor Davidson & Wells, O. penicillatum (Grosmann) Siemasko, Graphium sp., and yeasts.
