An information on new localities of several rare or overlooked lichenized fungi in Slovakia is given. Three species (Bacidina chloroticula, Bacidina delicata, Gonohymenia schleicheri) are referred as new records for Slovakia here; Parmelia flaventior, missing since 1933, was found in Pieniny Mts. Some critically endangered lichenized ascomycetes (e.g. Normandina pulchella, Thelotrema lepadinum, Parmelia pastillifera, Arthonia leucopellaea) or overlooked species (e.g. Dirina stenhammari, Biatora vernalis, Caloplaca biatorina, Caloplaca cerinelloides, Verrucaria bryoctona) are mentioned.
