The revision of specimens of the Cladonia pyxidata-chlorophaea group (lichenized Ascomycota) from northeastern Poland deposited in the herbarium collections of University in Bialystok

Abstract

In northeastern Poland, the chemical variation of the Cladonia chlorophaea-pyxidata group was much neglected, as TLC has not been used in delimitation of species differing in the chemistry. As a great part of herbal material of University in Bialystok from NE Poland was misidentified, I found my studies to be necessary. Based on the collection of 123 specimens deposited in Herbarium of University in Bialystok, nine species of the C. pyxidata-chlorophaea group are reported from NE Poland. The morphology, secondary chemistry, and ecology of examined lichens are presented and the list of localities is provided. The results revealed that C. fimbriata is the most common species in the northeastern Poland, comprising around 33% of the studied specimens. Cladonia conista, C. cryptochlorophaea, and C. merochlorophaea are known only from very few locations. This study shed light on the role of the lichens substances to diagnosis of the species of C. pyxidatachlorophaea group.

Analysis of Lichen Secondary Metabolites and Morphometrics in the Cladonia chlorophaea Species Group (Cladoniaceae, Lichenized Ascomycota) in Hungary

“…in the Vendvidék, W-Hungary only. Matwiejuk (2017) reported its frequency from pine forests. The localities in W-Hungary are also rich in pine forests.…”

“…Holien & Tønsberg (1985), Kowalewska et al . (2008) and Matwiejuk (2017) reported its frequency from pine forests. Localities of C. merochlorophaea in Hungary are more rich in pine forests than other regions within the country.…”

“…in the Bakony Mts, the Balaton Uplands and the Visegrádi Mts, lignicolous, while in NE Poland it was found on soil, wood and bark of Picea abies (L.) H.Karst. in open habitats and forests (Matwiejuk 2017).…”

“…Holien & Tønsberg 1985; Kowalewska et al . 2008; Tsurykau & Golubkov 2015; Matwiejuk 2017). Furthermore, Osyczka (2013) has performed a morphometric study – including quantitative and qualitative parameters – comparing six species ( C. asahinae J.W.Thomson, C. chlorophaea s.str.…”

New and noteworthy species of lichens from the Augustów Forest (northeastern Poland)

“…In the last decade, intensity of research on the distribution of lichens in Poland increased noticeably, using new methods and technologies. As a result, many new stands of different lichen species have been described [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20], including new stands from Augustów Forest.…”
