Abstract: The lichens Acarospora peliscypha, Caloplaca limonia, Candelaria pacifica, Cresporhaphis macrospora, Dimerella lutea, Lecanora barkmaniana, Ochrolechia arborea, Opegrapha gyrocarpa, Oxneria huculica, Physcia tribacioides, Punctelia borreri, Reichlingia leopoldii, Thelocarpon pallidum and the gyrophoric acid chemotype of Bryoria implexa as well as the lichenicolous fungi Cercidospora macrospora, Didymosphaeria futilis and Intralichen christiansenii are recorded for the region of Brandenburg and Berlin (Germany) for the first time. First records to Berlin are, moreover, the lichens and lichen-similar fungi Cyrtidula quercus, Leptorhaphis atomaria, Thelocarpon magnussonii, Vezdaea leprosa as well as the lichenicolous fungi Capronia peltigerae, Cladoniicola staurospora, Graphium aphthosae, Hawksworthiana peltigericola, Libertiella malmedyensis, Lichenodiplis lecanorae, Marchandiobasidium aurantiacum, Microcalicium disseminatum, Paranectria oropensis, Pezizella epithallina. Steinia geophana is first recorded with certainty from Berlin. Cliostomum corrugatum, Collema fuscovirens, Stereocaulon paschale were rediscovered to the Brandenburg-Berlin region. Two further observations of Nephromopsis laureri, a species recorded for the northern German lowlands only recently, were done; one of them in the Polish part of the region of Lower Lusatia. Occurrences of Hyperphyscia adglutinata, a species rediscovered recently in the Berlin-Brandenburg region after 200 years of absence, are rapidly increasing in number. Collema fuscovirens was repeatedly found on roofing tiles of concrete of a type previously widely used. Some further observations of rare or rarely recorded species are communicated. Cheiromycina globosa was found far from the northern Brandenburg/western Pomerania region for the first time. Just as most previous collections of this species, this material is associated with apothecia, whose anatomy and spores refer to Lecania koerberiana, which is otherwise not currently reported from Brandenburg. Two previously reported occurrences of Anaptychia ciliaris, a species under legal protection in Germany and critically endangered in Brandenburg, have been annihilated by demolition of their habitats.
