Lichens of larch Larix sp. in places of the Podlasie province (NE Poland)

Abstract

The paper presents the results of the research on the composition of lichen species of larch in the towns of Podlasie. 29 species of lichenicolous fungi have been recorded. A synthesis of epiphytic lichen biota of larch in Poland has been made. Despite the homogeneity of the substrate, the lichen biota of larch in Poland according to our own data and literature amounts to 107 species, some of which are rare. The richest lichen biota of larch in Poland occurs in mountainous areas. Many species that inhabit the bark of that phorophyte belong to the species extinct in Poland.
