New records of Parmelia ernstiae and P. serrana (Ascomycota, Parmeliaceae) in Poland

Abstract

The paper reports new localities of lichens <em>Parmelia ernstiae</em> and <em>P. serrana</em> in Poland. Both species are reported for the first time from the Polish part of the Sudety Mountains (southwestern part of the country). The new localities were found in the area of the Sowie Mountains (central part of the Sudety Mts) as well as Śnieżnik Massif and Bialskie Mountains (eastern part of the Sudety Mts). Most of the recorded specimens were associated with the bark of <em>Acer platanoides</em> and <em>A. pseudoplatanus</em>. <em>Parmelia ernstiae</em> and <em>P. serrana</em> are still poorly known species in Poland and often confused with similar taxon <em>P. saxatilis</em>. Therefore the morphological characteristics, chemical properties, ecology and distribution of these species are presented and briefly discussed.

Contribution to the knowledge of the distribution of <i>Parmelia</i> species (Parmeliaceae, Ascomycota) – New records confirmed by molecular data

“…A diagnostic feature that has been suggested by various authors as crucial in the identification of sorediate Parmelia species is the shape of rhizines (Divakar et al, 2005;Molina et al, 2011;Ossowska & Kukwa, 2016), as P. barrenoae has simple to furcate rhizines while P. sulcata, P. asiatica, and P. encryptata simple to squarrose. However, according to Hodkinson et al (2010) and Ossowska (2021), the rhizine shape may be confusing, which agrees with our observations on specimens from Chile. In one specimen (leg.…”

“…Here, we present the first records of P. ernstiae from Madeira (Portugal). 6C), simple to squarrose rhizines (Figure 6D), and the presence of salazinic acid in the medulla (see also Hale, 1987;Ossowska, 2021;ell et al, 2011). Morphologically and chemically similar species are P. barrenoae Divakar, M. C. Molina & A. Crespo, P. encryptata and P. asiatica A.…”

“…Parmelia ernstiae was previously separated from other isidiate species mainly on the basis of the presence of pruina, placement of isidia and the production of fatty acids and lobaric acid Molina et al, 2004;Ossowska, 2021;Ossowska et al, 2018) 2018) described as most common in P. ernstiae -a short, broad lobes with laminal isidia, which are present predominantly in central parts of thalli (Figure 4C). On the other hand, in specimens UGDA L-61382 and 61384 the lobes were longer and broader, and sublinear (Figure 4A, Figure 4B) as in P. saxatilis.…”

“…Parmelia sulcata belongs to the widespread Parmelia species and is common, especially in Europe (see Ossowska, 2021 and literature cited therein), although not all records are molecularly confirmed. In Chile this taxon was reported by Hale (1987) from the Magallanes and Stenroos (1991) from Tierra del Fuego, however, the molecular evidence for the occurrence of this species there was only provided by ell et al (2002) and Feuerer and ell (2002) from the department Magallanes y Antártica Chilena.…”

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

“…The Sudety Mountains are one of regions with the richest and the best-known lichen biota in Poland, with more than 1,000 species recorded to date (Kossowska, unpublished). Nevertheless, detailed studies still provide new data about the occurrence and distribution of lichen species (e.g., [1][2][3]). In addition, there are still some Sudetian mountain ranges where this group of organisms is poorly recognized.…”
