New and interesting lichen records from northeastern Poland

Abstract

Details are given of the occurrence of three rarely reported and poorly known lichen species from Poland area. Brief taxonomic, distributional, and ecological notes of <em>Agonimia flabelliformis</em>, <em>Bacidia pycnidiata</em>, and <em>Vezdaea aestivalis</em> have been provided. <em>Agonimia flabelliformis</em> have been reported for the first time from the northeastern part of Poland and <em>B. pycnidiata</em> from the northern part of the country. <em>Vezdaea aestivalis</em> has been rediscovered in northeastern Poland, nearly 150 years after its first and only recording in the region.
