Phylogeny of the Cetrarioid Core (Parmeliaceae) Based on Five
The Lichenologist 41(5): 489–511 (2009) © 2009 British Lichen Society doi:10.1017/S0024282909990090 Printed in the United Kingdom Phylogeny of the cetrarioid core (Parmeliaceae) based on five genetic markers Arne THELL, Filip HÖGNABBA, John A. ELIX, Tassilo FEUERER, Ingvar KÄRNEFELT, Leena MYLLYS, Tiina RANDLANE, Andres SAAG, Soili STENROOS, Teuvo AHTI and Mark R. D. SEAWARD Abstract: Fourteen genera belong to a monophyletic core of cetrarioid lichens, Ahtiana, Allocetraria, Arctocetraria, Cetraria, Cetrariella, Cetreliopsis, Flavocetraria, Kaernefeltia, Masonhalea, Nephromopsis, Tuckermanella, Tuckermannopsis, Usnocetraria and Vulpicida. A total of 71 samples representing 65 species (of 90 worldwide) and all type species of the genera are included in phylogentic analyses based on a complete ITS matrix and incomplete sets of group I intron, -tubulin, GAPDH and mtSSU sequences. Eleven of the species included in the study are analysed phylogenetically for the first time, and of the 178 sequences, 67 are newly constructed. Two phylogenetic trees, one based solely on the complete ITS-matrix and a second based on total information, are similar, but not entirely identical. About half of the species are gathered in a strongly supported clade composed of the genera Allocetraria, Cetraria s. str., Cetrariella and Vulpicida. Arctocetraria, Cetreliopsis, Kaernefeltia and Tuckermanella are monophyletic genera, whereas Cetraria, Flavocetraria and Tuckermannopsis are polyphyletic. The taxonomy in current use is compared with the phylogenetic results, and future, probable or potential adjustments to the phylogeny are discussed. The single non-DNA character with a strong correlation to phylogeny based on DNA-sequences is conidial shape. The secondary chemistry of the poorly known species Cetraria annae is analyzed for the first time; the cortex contains usnic acid and atranorin, whereas isonephrosterinic, nephrosterinic, lichesterinic, protolichesterinic and squamatic acids occur in the medulla. -
Genetic Variation Within and Among Populations of the Threatened Lichen Lobaria Pulmonaria in Switzerland and Implications for I

ZOLLER,* F. LUTZONI† and C. SCHEIDEGGER* *Swiss Federal Institute for Forest, Snow and Landscape Research, CH-8903 Birmensdorf, Switzerland, †Department of Botany, The Field Museum of Natural History, Chicago IL 60605, USA Abstract The foliose epiphytic lichen Lobaria pulmonaria has suffered a significant decline in European lowlands during the last decades and therefore is considered as endangered throughout Europe. An assessment of the genetic variability is necessary to formulate biologically sound conservation recommendations for this species. We investigated the genetic diversity of the fungal symbiont of L. pulmonaria using 143 specimens sampled from six populations (two small, one medium, three large) in the lowland, the Jura Moun- tains, the pre-Alps and the Alps of Switzerland. Among all nuclear and mitochondrial regions sequenced for this study, variability was found only in the internal transcribed spacer (ITS I), with three polymorphic sites, and in the nuclear ribosomal large subunit (nrLSU), with four polymorphic sites. The variable sites in the nrLSU are all located within a putative spliceosomal intron. We sequenced these two regions for 81 specimens and detected six genotypes. Two genotypes were common, two were found only in the more diverse populations and two were found only in one population each. There was no correlation between population size and genetic diversity. The highest genetic diversity was found in populations where the fungal symbiont is reproducing sexually. -

Diversity and Distribution of Lichen-Associated Fungi in the Ny-Ålesund Region (Svalbard, High Arctic) As Revealed by 454 Pyrosequencing
www.nature.com/scientificreports OPEN Diversity and distribution of lichen- associated fungi in the Ny-Ålesund Region (Svalbard, High Arctic) as Received: 31 March 2015 Accepted: 20 August 2015 revealed by 454 pyrosequencing Published: 14 October 2015 Tao Zhang1, Xin-Li Wei2, Yu-Qin Zhang1, Hong-Yu Liu1 & Li-Yan Yu1 This study assessed the diversity and distribution of fungal communities associated with seven lichen species in the Ny-Ålesund Region (Svalbard, High Arctic) using Roche 454 pyrosequencing with fungal-specific primers targeting the internal transcribed spacer (ITS) region of the ribosomal rRNA gene. Lichen-associated fungal communities showed high diversity, with a total of 42,259 reads belonging to 370 operational taxonomic units (OTUs) being found. Of these OTUs, 294 belonged to Ascomycota, 54 to Basidiomycota, 2 to Zygomycota, and 20 to unknown fungi. Leotiomycetes, Dothideomycetes, and Eurotiomycetes were the major classes, whereas the dominant orders were Helotiales, Capnodiales, and Chaetothyriales. Interestingly, most fungal OTUs were closely related to fungi from various habitats (e.g., soil, rock, plant tissues) in the Arctic, Antarctic and alpine regions, which suggests that living in association with lichen thalli may be a transient stage of life cycle for these fungi and that long-distance dispersal may be important to the fungi in the Arctic. In addition, host-related factors shaped the lichen-associated fungal communities in this region. Taken together, these results suggest that lichens thalli act as reservoirs of diverse fungi from various niches, which may improve our understanding of fungal evolution and ecology in the Arctic. The Arctic is one of the most pristine regions of the planet, and its environment exhibits extreme condi- tions (e.g., low temperature, strong winds, permafrost, and long periods of darkness and light) and offers unique opportunities to explore extremophiles. -
The Puzzle of Lichen Symbiosis

The examination will be conducted in English. Faculty examiner: Associate Professor Anne Pringle (University of Wisconsin-Madison, Department of Botany). Abstract Onuț-Brännström, I. 2017. The puzzle of lichen symbiosis. Pieces from Thamnolia. Digital Comprehensive Summaries of Uppsala Dissertations from the Faculty of Science and Technology 1503. 62 pp. Uppsala: Acta Universitatis Upsaliensis. ISBN 978-91-554-9887-0. Symbiosis brought important evolutionary novelties to life on Earth. Lichens, the symbiotic entities formed by fungi, photosynthetic organisms and bacteria, represent an example of a successful adaptation in surviving hostile environments. Yet many aspects of the lichen symbiosis remain unexplored. This thesis aims at bringing insights into lichen biology and the importance of symbiosis in adaptation. I am using as model system a successful colonizer of tundra and alpine environments, the worm lichens Thamnolia, which seem to only reproduce vegetatively through symbiotic propagules. When the genetic architecture of the mating locus of the symbiotic fungal partner was analyzed with genomic and transcriptomic data, a sexual self-incompatible life style was revealed. However, a screen of the mating types ratios across natural populations detected only one of the mating types, suggesting that Thamnolia has no potential for sexual reproduction because of lack of mating partners. -
Lichens of Tuckernuck Island Voucher List
The Nantucket Biodiversity Initiative A Checklist of the Lichens on Nantucket Island. Town of Nantucket, Nantucket County, MA, USA May 2008 Elizabeth Kneiper. 35 Woodchester Dr., Weston, MA 02493 Email: [email protected] Abstract: Collections made at 14 sites on Nantucket Island during the 2006 and 2007 NBI Weeks have added 53 species in 33 genera to the 2004 lichen list of 89 species in 37 genera. In all 21 genera have been added to the historical list for the island, increasing the number of genera to 61 and the species list to 148 species. Five species, Bacidia helicospora, Pyrrhospora quernea, Physcia pumilior, Cladonia abbreviatula and Usnea cornuta appear to be new records for Massachusetts. Ramalina willeyi is well established on the island as are other Ramalinas thought to be uncommon in the region, such as Usnea mutabilis, Ramalina americana and Ramalina farinacea. Skyttea radiatilis and Mycoglaena sp. (saprophytic fungi related to lichens and lichenicolous fungi) and Naetrocymbe punctiforms, a lichenicolous fungus, are reported for the island. This lichen inventory work is a continuation of the work started during the 2004 NBI Week. Different lichen assemblages develop in different plant communities and on different substrates. The aim of this work was to survey habitats not examined in 2004 to document the lichen diversity in diverse sites and to attempt to document lichen species recorded for Nantucket Island in The Vascular and Non-Vascular Flora of Nantucket, Tuckernuck and Muskeget Islands by Sorries and Dunwiddie in 1996. Scope of the Inventory and Methods The localities of the sites surveyed in 2006-2007 are listed below. -
A New Species of Allocetraria (Parmeliaceae, Ascomycota) in China

Monitoring Air Quality in Class I Wilderness Areas of the Northeastern United States Using Lichens and Bryophytes Alison C
United States Department of Agriculture Monitoring Air Quality in Class I Wilderness Areas of the Northeastern United States Using Lichens and Bryophytes Alison C. Dibble, James W. Hinds, Ralph Perron, Natalie Cleavitt, Richard L. Poirot, and Linda H. Pardo Forest Service Northern Research Station General Technical Report NRS-165 December 2016 1 Abstract To address a need for air quality and lichen monitoring information for the Northeast, we compared bulk chemistry data from 2011-2013 to baseline surveys from 1988 and 1993 in three Class I Wilderness areas of New Hampshire and Vermont. Plots were within the White Mountain National Forest (Presidential Range—Dry River Wilderness and Great Gulf Wilderness, New Hampshire) and the Green Mountain National Forest (Lye Brook Wilderness, Vermont). We sampled epiphyte communities and found 58 macrolichen species and 55 bryophyte species. We also analyzed bulk samples for total N, total S, and 27 additional elements. We detected a decrease in Pb at the level of the National Forest and in a subset of plots. Low lichen richness and poor thallus condition at Lye Brook corresponded to higher N and S levels at these sites. Lichen thallus condition was best where lichen species richness was also high. Highest Hg content, from a limited subset, was on the east slope of Mt. Washington near the head of Great Gulf. Most dominant lichens in good condition were associated with conifer boles or acidic substrates. The status regarding N and S tolerance for many lichens in the northeastern United States is not clear, so the influence of N pollution on community data cannot be fully assessed. -

Persoonia 37, 2016: 1–12 www.ingentaconnect.com/content/nhn/pimj RESEARCH ARTICLE http://dx.doi.org/10.3767/003158516X688081 Sharpening the species boundaries in the Cladonia mediterranea complex (Cladoniaceae, Ascomycota) R. Pino-Bodas1, I. Pérez-Vargas2, S. Stenroos1, T. Ahti1, A.R. Burgaz 3 Key words Abstract The complex Cladonia mediterranea belongs to the section Impexae and is formed by C. azorica, C. maca ronesica and C. mediterranea. These species are basically distributed in the Mediterranean and Macaronesian coalescence Regions. In the present work the limits between the species of this complex are re-examined. To this end, the mor- Iberian Peninsula phological characters were studied along with the secondary metabolites and the DNA sequences from three loci integrative taxonomy (ITS rDNA, IGS rDNA and rpb2). The morphological data were studied by principal component analysis (PCA), while lichen forming fungi the DNA sequences were analyzed using several approaches available to delimit species: genealogical concor dance Macaronesia phylogenetic species recognition, species tree (BEAST* and spedeSTEM) and cohesion species recognition. In molecular systematic addition, the genealogical sorting index was used in order to assess the monophyly of the species. The different species delimitation procedures used in our study turned out to be highly congruent with respect to the limits they establish, but these taxonomy limits are not the ones separating the prior species. Either the morphological analysis or the different approaches to species delimitation indicate that C. mediterranea is a different species from C. macaronesica, while C. azorica and C. macaronesica, which are reduced to synonyms of C. portentosa, constitute a separate lineage.
