Accepted: March 29, 2016) ABSTRACT. This paper presents new distribution stands for 70 species of lichenized town from Łomża town (Podlasie, NE Poland). The investigations in the area of Łomża were carried out in the years 2014–2015, on 34 research stands. Seven species have been put on the Red list of the lichens in Poland (Cieśliński et al. 2006), including Rhizocarpon lavatum in critically endangered – CR, Ramalina fastigiata, R. fraxinea in the endangered category – EN, in the Ramalina farinacea in the vulnerable category – VU and Evernia prunastri, Hypogymnia tubulosa, Physcia aipolia in the category of near threatened – NT and five have been put under legal protection, two of which are strictly (Ramalina fastigiata, R. fraxinea) and three of which are partial- ly protected (Cladonia arbuscula, Hypogymnia tubulosa, Ramalina farinacea). The lichens occur on following substrate types: soil, decaying wood, bark of all trees and shrubs species, boulders, concrete, foundation, mortar, plaster and bryophytes.

MATERIALS AND METHODS Fieldwork research. The investigations in the area of Łomża were carried out in the years 2014–2015, on 34 research localites (Fig. 1). These stands were established within different places. The habitat was considered a stand within which the census of li- chens was made from all available substrates. The epiphytic lichens were examined for individual trees with a diameter of trunks > 30 cm. At each stand at least five trees were monitored. At each location all species of lichens on the bark of trees from the base up to 2.5 m were recorded. Taxonomic identification. For most taxa, tax- onomic identification was carried out in laboratory conditions. The collected specimens were deter- mined on the basis of morphological and anatomical characters. Lichens were also determined based on the presence of secondary metabolites – test reac- tions. Thin-layer chromatography (TLC) was used to identify the types of secondary metabolites, mainly from the genus Cladonia, Lepraria and Rhizocarpon. This method was conducted in accordance with the guidelines from ORANGE et al. (2001). The species have been named according to DIEDERICH et al. (2014) and species Melanelixia to HAWKSWORTH et al. (2008, 2011), Circinaria calcarea to NORDIN et al. (2010) and Calogaya decipiens, C. pusilla, Flavoplaca citrina, F. oasis, Fig. 1.
