Noteworthy Lichenized and Lichenicolous Fungi of Open-Canopy Oak Stands in East-Central Europe

Eighteen species of lichenized and two species of lichenicolous fungi from oak stands of east-central Europe's rural landscapes are presented. Rinodina isidioides is new to eastern Europe and the Carpathians, Abrothallus microspermus is new to the Carpathians, Rinodina excrescens is new to the eastern Carpathians, Biatora pontica is new to the Polish Carpathians, Lecanora substerilis, Ramonia chrysophaea and Verrucaria viridigrana are new to the Polish Carpathians and Poland, and others are new to Hungary, Romania or Ukraine. Distinguishing characters are emphasised and notes on ecology as well as global and Carpathian distributions are given. Open-canopy oak stands and solitary oaks in wood-pastures are important for the protection of the lichen diversity of the Carpathians and need the special attention of conservation authorities and local stakeholders.
