New and noteworthy lichens from Lithuania.

Four species of lichens were reported as new to Lithuania: Flavoplaca arcis, Kuettlingeria teicholyta, Ramalina europaea, Xanthoria calcicola. Of these, two calcicolous lichens, Kuettlingeria teicholyta and Flavoplaca arcis, were recorded for the first time in the Baltic States. Two species, namely Cladonia turgida and Peltigera aphthosa, previously considered extinct, were re-found after more than 50 years in Lithuania. The conservation value of some of the listed species was discussed. [ABSTRACT FROM AUTHOR]
