This substrate is connected with the igneous intrusion into the country rocks and is characterized by a richer chemical and mineral composition than the surrounding rock bodies. In the six analyzed sites, a total of 48 saxicolous lichen species were found. Hornfels as a substrate for lichen vegetation is distinguished by the presence of lichens typical for rocks rich in metal compounds, in the study area represented by </span><em><span style="font-weight: 400;">Rhizocarpon oederi</span></em><span style="font-weight: 400;">, </span><em><span style="font-weight: 400;">Lecidea silacea</span></em><span style="font-weight: 400;"> and </span><em><span style="font-weight: 400;">Porpidia melinodes</span></em><span style="font-weight: 400;">, and lichens that prefer mineral-enriched rocks, like </span><em><span style="font-weight: 400;">Lecanora campestris</span></em><span style="font-weight: 400;">, </span><em><span style="font-weight: 400;">L. rupicola</span></em><span style="font-weight: 400;">, </span><em><span style="font-weight: 400;">Lecidea fuscoatra</span></em><span style="font-weight: 400;">, </span><em><span style="font-weight: 400;">Porpidia cinereoatra</span></em><span style="font-weight: 400;"> and </span><em><span style="font-weight: 400;">Rimularia gibbosa</span></em><span style="font-weight: 400;">. The three mentioned metallophilous species are </span><span style="font-weight: 400;">some of the rarest components of the lichen biota in Poland, known from single localities. Other rare and locally endangered lichens recorded on hornfels include </span><em><span style="font-weight: 400;">Lambiella furvella</span></em><span style="font-weight: 400;">, </span><em><span style="font-weight: 400;">Stereocaulon dactylophyllum</span></em><span style="font-weight: 400;"> and </span><em><span style="font-weight: 400;">Umbilicaria pustulata</span></em><span style="font-weight: 400;">.</span></p> ER -
