Contribution to the knowledge of some poorly known lichens in Poland. III. Trapelia corticola and the genus Vezdaea
New data on four Vezdaea species and Trapelia corticola (lichenized Ascomycota, Lecanoromycetes) are presented for Poland. V. acicularis is reported as new to the country and records of V. retigera are newly published. Further collections of the rare V. stipitata and relatively common V. aestivalis are presented. New localities of Trapelia corticola suggest that the species is locally common in the mountains. Notes on the taxonomy, world distribution and habitat preferences for all species are included. Additionally, Vezdaea aestivalis is reported for the first time for Romania.
