Records are presented for 99 lichens, 15 lichenicolous fungi, and a parasitic and a saprophytic fungus.

New to Lower Saxony are Bacidia subincompta, Epigloea urosperma and Pertusaria pupillaris. 23 species were rediscovered in Saxony-Anhalt mostly after a very long time, including the following which were considered extinct in the Red List: Anaptychia ciliaris, Arthonia vinosa, Bacidina egenula, Biatora efflorescens, Icmadophila ericetorum, Lecanactis abietina, Lecanora subcarnea and Lecidea tesselata var. tesselata. Bacidia beckhausii and Frutidella pullata have been rediscovered in Lower Saxony. Remarkable second records for Saxony-Anhalt are Gregorella humida, Polyblastia philaea and Synalissa ramulosa. Lichenomphalia umbellifera is recorded for the first time from the lowlands of Saxony-Anhalt.
