Prvý záznam o výskyte trúdnika Fomes fomentarius na smreku v Karpatoch s poznámkami o jeho výskyte na ihličnatých drevinách v Európe

Abstract

In Carpathians, the tinder polypore Fomes fomentarius (L.) Fr. is a well-known fungus commonly classified as frequent wood decomposer typical of beech forest stands. It is one of the most common wood-decaying macrofungi influencing structural stability, biomechanical properties and tree vitality of beech (Fagus sylvatica L.). Until 2023, no published records of this polypore on Norway spruce Picea abies (L.) H. Karst. Were known from the Carpathian Mountains. In this paper we present the first occurrence of the F. fomentarius in the Těšín Silesia (Moravian-Silesian region) in the Czech Republic. It is reported from the forest edge of a Norway spruce stand near the village of Horní Lomná in Frýdek-Místek District, which is located in this range (41°35‘ N, 29°07‘ E). Data on occurrence on coniferous hosts throughout Europe including some unpublished data are summarized.
