Composition of the polypore communities of four forest areas in southern Central Finland

Abstract

The total polypore flora was studied in four nearby forest areas in southern Central Finland (pro ince Etela-Hame), 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 (B res.) Niemelii, Onnia triquetra (Lenz) Imaz., Rigidoporus vitreus (Fr.) Donk, Strangulidium rennyi (Berk. & Br.) Pouz., Tyromyces lowei (Pi!.) 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 /apponica (Rom.) Sing., Fomitopsis rosea (Fr.) Karst. , Phellinus ferrugineofuscus (Karst.) Bourd. and Phlebia centrifuga Karst. on fallen trunks of Picea abtes (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.

Polypore survey of Finland 4. Phaeolus, Fistulina, Ganoderma and Ischnoderma

“…Along the southern coast (A-U), the galls are found in 1.9 % of all fruit bodies; in the Lake District (EK-PK) they occupy 11.8% of the fruit bodies, but they were not found in the marginal northern area (KP-PP). Adult A. wankowiczi has not been reported from Finland (Kotiranta & Niemela 1981), but the larvae in the galls closely resemble those illustrated by Eisfelder and Herschel (1966).…”

Notes on some rare polypores, found in Russia 2. Junghuhnia vitellina sp. nova, plus genera Cinereomyces and Skeletocutis

“…(Spirin & Shirokov 2002). Similar preferences were noted by Finnish authors (Kotiranta & Niemelä 1981, Renvall et al 1991. One collection is from dead basidiocarp of Phlebia centrifuga (LE 211400).…”

Polypores in the parks and forests of the City of Helsinki

“…A very rare species, found in the forests of eastern Helsinki. Earlier Finnish finds of this species (as A. plicata) were published by Niemela (1978a) and Kotiranta and Niemela (1981). The Fennoscandian distribution was mapped and the name change discussed by Niemela (1985a) .…”

“…In this connection we would like to mention the study of Kotiranta and Niemela ( 1981 ), which was also based on a Cand.Phil. thesis (Kotiranta 1980).…”
