The paper presents the results of several years of mycological studies carried out in Poland, in the Western Sudety Mountains (the Karkonosze, Kaczawskie, Izera, and Rudawy Janowickie mountains), Western Sudety Foothills (the Izerskie and Kaczawskie Foothills), and adjacent regions, such as the Jelenia Góra Valley, Lubawska Gate, and Sudety Foreland (the Niemczańsko-Strzelińskie Hills). During the study, the presence of 985 fungal taxa (species, varieties, and forms) was recorded; of these, 66 had hitherto not been observed in Poland.
