The lichen family Parmeliaceae in Poland. I. The genus Parmotrema

Abstract

The paper presents the results of study on four <em>Parmotrema</em> species in Poland, <em>P. arnoldii, P. crinitum, P. perlatum</em> and <em>P. stuppeum</em>. They are mainly known from southern part of the country, mostly in the Carpathians. <em>P. perlatum</em> is reported also from Northern Poland and Central Poland. For <em>P. stuppeum</em>, so far known from single locality only, three new sites are reported. All the species seem to be rare and endangered in Poland. This work is the first part of a larger series which will present data on selected genera of the lichen family <em>Parmeliaceae</em> in Poland.
