New and noteworthy records of lichens in the Czech Republic

A commented overview of selected new and noteworthy lichens collected especially at the territory of the Czech Republic is given. A few remarkable collections from other European countries (Austria, France, Germany, Romania, Russia, Slovakia, Sweden) are also included. Apart from lichens, several lichenicolous and non-lichenized fungi traditionally treated by lichenologists (e. g. some species of the polyphyletic order Caliciales s. l.) are also included in the list. The vast majority of the mentioned species was collected in the Šumava Mts - a highly forested area ranging along the border with Austria and Germany - at present one of the most preserved regions in the Czech Republic. Several findings are interesting from the lichenogeographical point of view (e. g. Agonimia allobata, Anzina carneonivea, Bacidia carneoglauca, B. viridifarinosa, Chaenotheca sphaerocephala, Fellhaneropsis myrtillicola, Japewia subaurifera, Melaspilea granitophila, Micarea anterior, M. contexta, M. deminuta, M. lapillicola, M. marginata, M. vulpinaris, Polyblastia gothica, Porina hibernica, Porpidia ochrolemma, Rinodina interpolata, Scoliciosporum curvatum, S. schadeanum, Trapeliopsis glaucolepidea etc.). Some of the treated lichens are probably undercollected to a great degree (e. g. Anisomeridium nyssaegenum, Arthonia muscigena, Caloplaca obscurella, Micarea botryoides, M. myriocarpa, M. polycarpella, Psilolechia clavulifera and taxa of the genera Absconditella, Macentina, Vezdaea etc.). Altogether 82 taxa are discussed, of which 53 are new for the Czech Republic, of which 10 are new for Central Europe (Absconditella pauxilla, Chaenotheca sphaerocephala, Chaenothecopsis epithallina, C. nigra, Japewia subaurifera, Micarea contexta, M. deminuta, M. lapillicola, M. marginata, M. vulpinaris). Furthermore, some of the collections included represent other new country records. The following species are presumably reported for the first time from the respective countries: Absconditella celata (Slovakia), Agonimia allobata (Slovakia), Catillaria alba (Slovakia), Chaenotheca sphaerocephala (Romania), Fellhaneropsis vezdae (Slovakia), Hypocenomyce leucococca (Romania), Macentina dictyospora (Slovakia), Micarea hedlundii (Slovakia), Micarea lynceola (France), Micarea myriocarpa (Austria), Micarea polycarpella (Sweden), Micarea vulpinaris (Germany), Porina leptalea (Sweden), Scoliciosporum curvatum (Romania, Slovakia), and Trapelia corticola (Romania). The following new combination - Micarea lynceola (Th. Fr.) Palice comb. nov. is proposed. Trapeliopsis percrenata is here considered to be conspecific with T. glaucolepidea.
