Synonymizations and lectotypifications of some lecideoid lichens (Ascomycota, Lecanoromycetes) described from Finland or Sweden

Between 1850 and 1950, hundreds of lecideoid lichen-forming fungi were described from Fennoscandia, mainly in the genus Lecidea. The status many these species is still uncertain some have not been revised since their description. We examined types nomenclature nine such taxa, found that they represent synonyms earlier species: Bacidia dolera (= Lecidea albofuscescens), aviaria Rhizocarpon richardii), L. cavernarum Porpidia soredizodes), cuculi Schaereria fuscocinerea), frustulenta Micarea subnigrata), ivalensis Carbonea vorticosa), melaphanoides Scoliciosporum intrusum), mustialensis albofuscescens) submilvina Miriquidica leucophaea). In addition, we three Lecanora cadubriae: Biatora admixta, B. pinicola subinsequens. Lectotypes are designated for basionyms admixta Th.Fr., Th.Fr. ex Hellb., Vain., fuscocinerea Nyl., Nyl. subinsequens
