Abstract: The Finnish distribution is mapped for five polypore species. Phaeolus schweinitzii (Fr.) Pat. has rare occurrences almost throughout the country, mainly on Larix sibirica and Pinus sylvestris. Fistulina hepatica Schaeff.: Fr. is strictly Hemiboreal, growing on Quercus robur and (one record) Castanea sativa. Ganoderma lipsiense (Batsch) Atk. (G. applanatum) is a polyphagous saproparasite, common in the Hemiboreal and Southern boreal zones and rarer in the Middle boreal zone. Ganoderma lucidum (Curt.: Fr.) Karst. favours large stumps of Alnus glutinosa and has rare occurrences in the Hemiboreal and Southern boreal zones only. Ischnoderma benzoinum (Wahl.) Karst. is distributed over the whole of Finland, but is common only in the south. It grows mostly on Picea abies, less often on Pinus sylvestris, and exceptionally on a few other hosts. None of these fungi cause notable economic losses as decaying agents.
