Abstract

Himelbrant, D., Stepanchikova, I., Korolev, K., Motiejūnaitė, J. & Petrenko, D. 2020. Forty species of lichens, lichenicolous and calicioid fungi new for the Kaliningrad region (former Ostpreusen) with additional noteworthy records. – Herzogia 33: 34–56.The most important results of lichenological fieldwork in the northern part of the Kaliningrad region (former Ostpreusen), conducted in 2019, are reported. Forty species are new to the Kaliningrad region, of which Fuscidea lightfootii and Xanthoparmelia mougeotii are also new to Russia. Jamesiella anastomosans and Reichlingia leopoldii were otherwise known in Russia only from the Caucasus. Also treated are another sixteen species which are rare or protected in the region, or are indicators of biologically valuable forests. The most diverse and valuable fraction of the lichen diversity in the northern part of the Kaliningrad region was observed in the remnants of old-growth Norway spruce-broadleaved, broadleaved, and black alder forests, as well as in old-growth broadleaved alleys and manor parks.
