Abstract

New distributional data are given on 52 lichen species from Norway. Anisomeridium nyssaegenum, Lecideasphaerella, Sarcosagium campestre, Scoliciosporum perpusillum and Strangospora pinicola are new to Norway. 30 species are new to central Norway. A chemotype of Lecanora cadubriae with virensic acid is reported for the first time and a PD-negative chemotype of Lobaria scrobiculata is new to Europe. Maps on the distribution in Norway are provided for Bacidia subincompta, Cliostomum griffithii, Lecanora cadubriae, Micarea cinerea and Opegrapha rufescens. A map is provided concerning the European distribution of Cladonia metacorallifera var. reagens.
