Abstract: The total polypore flora was studied in four nearby forest areas in southern Central Finland (province Etelä-Häme), including the Edessalo nature reserve, and the Vesijako National Park, which is one of the oldest and densest virgin spruce forests in Finland. The field work was done in the years 1978-1980, when 855 specimens were collected and about 720 sight records were made. In all, 97 species were found.
The ecology of most of the species is discussed, and their abundance and the host tree species are presented. Species reported as new to Finland are Antrodia salicina (Bres.) Niemelä, Onnia triquetra (Lenz) Imaz., Rigidoporus vitreus (Fr.) Donk, Strangulidium rennyi (Berk. & Br.) Pouz., Tyromyces lowei (Pil.) Dom. and T. undosus (Peck) Murr. The total distribution of some rare species in Finland is given, and the concept of the so-called ‘taiga element’ is discussed. Preliminary observations are presented on the existence of some fungal communities e.g., the co-occurrence of Amylocystis lapponica (Rom.) Sing., Fomitopsis rosea (Fr.) Karst., Phellinus ferrugineofuscus (Karst.) Bourd. and Phlebia centrifuga Karst. on fallen trunks of Picea abies (L.) Karsten. The susceptibility of different tree species to wood-rotting polypores is discussed, and problems in the taxonomy of some rare species are briefly reviewed.
