Abstract Three species of lichens and four species of lichenicolous fungi were reported as new to Lithuania: Cercidospora macrospora, Didymocyrtis cladoniicola, Miriquidica leucophaea, Montanelia disjuncta, Plectocarpon lichenum, Porpidia nigrocruenta and Telogalla olivieri. Of these, two species, Didymocyrtis cladoniicola and Miriquidica leucophaea, were recorded for the first time in the Baltic States. Three lichens, namely Lecanora sulphurea, Protoparmelia badia and Punctelia subrudecta previously known in Lithuania from literature data were only confirmed with certainty for the first time.
