Abstract:  Distribution maps are presented for the following polypore species in Finland: Coltricia cinnamomea (Jacq.: S.F. Gray) Murrill, C. perennis (L.: Fr.) Murrill, Inonotopsis subiculosa (Peck) Parmasto, Inonotus dryophilus (Berk.) Murrill, I. hispidus (Bull.: Fr.) Karst. (new to Finland), I. obliquus (Fr.) Pilát, I. radiatus (Sow.: Fr.) Karst., I. rheades (Pers.) Karst., Onnia leporina (Fr.) Jahn, O. tomentosa (Fr.) Karst. and O. triquetra (Lenz) Imazeki. The host plants are listed for each species, the ecology and pathogenicity of the species are discussed, and an evaluation made of their economic importance as pathogens and wood-rotting fungi on merchantable timber and ornamental trees and shrubs. Of these the most harmful species are Inonotus obliquus (especially on birch) and Onnia leporina (on spruce).
The concepts of the genera are briefly discussed, and some author citations are altered to accord with the Code of Nomenclature enacted in 1981.
