The purpose of this study was to assess the contemporary conditions of the lichen biota in the eastern part of the “Paprocie Serpentynitowe w Masywie Ślęży” ecological area in the Sudetes Foothills. The studies were carried out at three localities selected from 10 sites that were designed to protect the Asplenium fern genus. A total of 47 lichen species were found in the three localities. For each of the recorded species, the state of preservation in the Ślęża Massif area was assessed according to three factors: frequency at all three localities, general viability of the thalli, and stability in occurrence on the habitat. Stability was defined based on contemporary and historical data. From the analysis, most of the species (17) were classified as taxa with “moderate preservation status” in the study area. However, the preservation status of the 18 newly recorded taxa was defined as “insufficient data” due to the lack of previous records. Other species received a “very good preservation status” (three taxa) and “good preservation status” (nine taxa). The analyses allowed us to document the current number of taxa, determine their health condition, and indicate trends in the transformation within the lichen biota of the serpentinite rocks in the study area. Moreover, some actions were proposed to actively protect the valuable lichens in the ecological area of “Paprocie Serpentynitowe w Masywie Ślęży.”

The paper reports new localities of lichens Parmelia ernstiae and P. serrana in Poland. Both species are reported for the first time from the Polish part of the Sudety Mountains (southwestern part of the country). The new localities were found in the area of the Sowie Mountains (central part of the Sudety Mts) as well as Śnieżnik Massif and Bialskie Mountains (eastern part of the Sudety Mts). Most of the recorded specimens were associated with the bark of Acer platanoides and A. pseudoplatanus. Parmelia ernstiae and P. serrana are still poorly known species in Poland and often confused with similar taxon P. saxatilis. Therefore the morphological characteristics, chemical properties, ecology and distribution of these species are presented and briefly discussed.

Records of two lichenicolous and nine lichen-forming fungi found in the southwestern part of Poland are presented. All of the reported species are very rare and they have only a few scattered localities in the country. One of them, Lecanora pannonica, is reported for the second time from Poland. Additionally, the new, contemporary records of Cercidospora macrospora, Rhizocarpon disporum, R. viridiatrum and Stereocaulon pileatum in Lower Silesia were noted. These species were known only from historical collections in the study area. Furthermore, Lecidea fuscoatra has been found a new host for Sagediopsis barbara. All of the localities of recorded species were found on natural outcrops of basalt rocks.
