Agonimia species and other rare lichens in Central Poland

Abstract

Eight lichen species are presented. Four of them: <em>Agonimia flabelliformis, A. opuntiella, A. tristicula</em> and <em>Micarea adnata</em> are new to Central Poland. <em>Caloplaca cerina</em> var. <em>chloroleuca, Micarea hedlundii</em> and <em>Porina leptalea</em> are very rare in the Świętokrzyskie Mts and in Central Poland.

Additions to the lichen biota of the Sudety Mountains. I. Records from the Karkonosze Mountains

“…Porina leptalea is considered rare and endangered in Poland (category EN on the Polish red list of lichens [11]). All the known localities of this species are concentrated in mountainous parts of the country [38][39][40][41][42]. In the Sudety Mountains, it is known from several contemporary localities in Masyw Śnieżnika [43], Pogórze Kaczawskie [16], and Karkonosze Mountains [44].…”

New and interesting lichen records from northeastern Poland

“…Agonimia flabelliformis prefers humid, shaded, mossy places within deciduous forest ecosystems, where it usually grows epibryophytically over bark (at the base of trees and their roots) or occasionally on soil, rocks, wood, or plant debris [13][14][15][16][17]. At the new collection sites, the species was growing on corticolous bryophytes (Hypnum cupressiforme) and directly on bark at the base of mature oak trees.…”

“…In Poland, it has been noted in only three localities ( Fig. 1), in southern [14], central [15], and northwestern parts of the country [20].…”
