    Based on collections of P. Czarnota deposited in the GPN herbarium, 8 species of Rhizocarpon are reported from the Gorce Mountains. Two of them, R. lavatum and R. reductum are reported from the Gorce Mts for the first time, instead of erroneously determined R. obscuratum. This species was previously misinterpreted due to taxonomic and nomenclatoric uncertainties.W zbiorach zielnikowych GPN z Gorców stwierdzono 8 gatunków Rhizocarpon (R. distinctum, R. geminatum, R. geographicum, R. lavatum, R. lecanorinum, R. petraeum, R. polycarpum, R. reductum). Po raz pierwszy dla tego terenu podano dwa gatunki Rhizocarpon lavatum i R. reductum. Wyróżnienie nowych gatunków związane jest ze zmianą ujęcia taksonomicznego i nomenklatorycznego reprezentantów grupy Rhizocarpon obscuratum auct., charakteryzujących się bezbarwnymi i murkowatymi zarodnikami (Fryday 2000; Ihlen 2004). W oznaczeniu tych gatunków wykorzystano chromatografię cienkowarstwową (TLC), która pozwoliła określić ich cechy chemiczne: obecność kwasu stiktowego u R. reductum i brak wtórnych metabolitów u R. lavatum. Pierwszy z tych gatunków charakteryzuje się ponadto mniejszymi i mniej podzielonymi zarodnikami [24.0-26.0×8.0-10.0 μm, (6-)8-10(-12) komórek], podczas gdy zarodniki R. lavatum osiągają rozmiary 30.0-42.0×14.0-18.0 μm i są podzielone na (8-)10-14(-18) komórek

    A paper presents a list of 89 species found in Supraśl town (Podlasie, NE Poland). The investigations in the area of Supraśl were carried out in 2013–2014, on 41 research stands. Eighteen species are considered to be threatened in Poland. The lichens occur on all substrate types: soil, decaying wood, bark of all trees and shrubs species, boulders, concrete, foundation, mortar, plaster and bryophytes. Valuable components of the lichen biota belong mostly to the group of threatened species not only on the regional, but also on the national scale. There are: Anaptychia ciliaris, Pleurosticta acetabulum, Ramalina fastigiata and others
