Abstract

OTTE, V. 2011. Usnea flavocardia found in Germany. — Herzogia 24: 151-154.

Usnea flavocardia was found in Lower Lusatia, Brandenburg, far northeast of its known Western and Southern European distribution range. There is no doubt that it is a recent colonisation in this area that was heavily influenced by S0₂ pollution during the 20^th century. The appearance of U. flavocardia could be the result of milder winters of the last few years, but the possibility that the species was previously overlooked in Brandenburg cannot be ruled out.
