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. -

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. 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. -
Molecular Phylogenetic Study at the Generic Boundary Between the Lichen-Forming Fungi Caloplaca and Xanthoria (Ascomycota, Teloschistaceae)

Farimagsgade 2D, DK-1353 Copenhagen K, Denmark. 2 Department of Biology, Duke University, Durham, NC 27708-0338, USA. E-mail : [email protected] Received 5 December 2001; accepted 5 August 2003. A molecular phylogenetic analysis of rDNA was performed for seven Caloplaca, seven Xanthoria, one Fulgensia and five outgroup species. Phylogenetic hypotheses are constructed based on nuclear small and large subunit rDNA, separately and in combination. Three strongly supported major monophyletic groups were revealed within the Teloschistaceae. One group represents the Xanthoria fallax-group. The second group includes three subgroups: (1) X. parietina and X. elegans; (2) basal placodioid Caloplaca species followed by speciations leading to X. polycarpa and X. candelaria; and (3) a mixture of placodioid and endolithic Caloplaca species. The third main monophyletic group represents a heterogeneous assemblage of Caloplaca and Fulgensia species with a drastically different metabolite content. We report here that the two genera Caloplaca and Xanthoria, as well as the subgenus Gasparrinia, are all polyphyletic. The taxonomic significance of thallus morphology in Teloschistaceae and the current delimitation of the genus Xanthoria is discussed in light of these results. INTRODUCTION Taxonomy of Teloschistaceae and its genera The Teloschistaceae is a well-delimited family of Hawksworth & Eriksson (1986) assigned the Teloschis- lichenized fungi. -

Mycosphere 4(5), 926–928, Doi 10.5943/mycosphere/4/5/4 Abstract Pronectria rhizocarpicola, a new species of Bionectriaceae is described and illustrated. It is growing parasitically on Rhizocarpon geographicum in the Swiss Alps. Key words – Ascomycota – bionectriaceae – hypocreales Introduction The genus Pronectria currently comprises 44 species, including 2 algicolous and 42 lichenicolous species. Most of the lichenicolous species are living on foliose and fruticose lichens (32 species), only a few on squamulose and crustose lichens (10 species). No species of the genus was ever reported from the host genus Rhizocarpon. Materials and methods Morphological and anatomical observations were made using standard microscopic techniques. Microscopic measurements were made on hand-cut sections mounted in water with an accuracy up to 0.5 µm. Measurements of ascospores and asci are recorded as (minimum–) X-σ X – X+σ X (–maximum) followed by the number of measurements.

Box 140, FI-00251 Helsinki, Finland. 5Department of Biology, University of Padua, via Ugo Bassi 58/b, 35121, Padova Abstract The freshwater lichens Verrucaria elaeomelaena, V. alpicola, and V. funckii (Verrucariaceae/Ascomycota) have long been confused with V. margacea and V. placida and conclusions on the substratum preference and distribution have been obscured due to misidentifications. Independent phylogenetic analyses of a multigene dataset (RPB1, mtSSU, nuLSU) and an ITS- dataset combined with morphological and ecological characters confirm that the Verrucaria elaeomelaena agg. consists of several cryptic taxa. It includes V. elaeomelaena s.str. with mostly grey to mid-brown thalli and transparent exciple base which cannot be distinguished morphologically from several other unnamed clades from low elevations, the semi-cryptic V. humida spec. nov., which is characterised by smaller perithecia, shorter and more elongated spores compared to other species in this group and V. -

Jørgensen: Dept. of Natural History, University Museum of Bergen, Box 7800, NO –5020 Bergen, Norway. Abstract: We estimated phylogeny in the lichen-forming ascomycete family Pannariaceae. We specifically modelled spatial (across-site) heterogeneity in nucleotide frequencies, as models not incorporating this heterogeneity were found to be inadequate for our data. Model adequacy was measured here as the ability of the model to reconstruct nucleotide diversity per site in the original sequence data. A potential non-orthologue in the internal transcribed spacer region (ITS) of Degelia plumbea was observed. We propose a revised generic classification for the Pannariaceae, accepting 30 genera, based on our phylogeny, previously published phylogenies, as well as morphological and chemical data available. -

Revisions of British and Irish Lichens
Revisions of British and Irish Lichens Volume 9 February 2021 Peltigerales: Pannariaceae Cover image: Pectenia atlantica, on bark of Fraxinus excelsior, Strath Croe, Kintail, Wester Ross. Revisions of British and Irish Lichens is a free-to-access serial publication under the auspices of the British Lichen Society, that charts changes in our understanding of the lichens and lichenicolous fungi of Great Britain and Ireland. Each volume will be devoted to a particular family (or group of families), and will include descriptions, keys, habitat and distribution data for all the species included. The maps are based on information from the BLS Lichen Database, that also includes data from the historical Mapping Scheme and the Lichen Ireland database. The choice of subject for each volume will depend on the extent of changes in classification for the families concerned, and the number of newly recognized species since previous treatments. To date, accounts of lichens from our region have been published in book form. However, the time taken to compile new printed editions of the entire lichen biota of Britain and Ireland is extensive, and many parts are out-of-date even as they are published. Issuing updates as a serial electronic publication means that important changes in understanding of our lichens can be made available with a shorter delay. The accounts may also be compiled at intervals into complete printed accounts, as new editions of the Lichens of Great Britain and Ireland. Editorial Board Dr P.F.

An Evolving Phylogenetically Based Taxonomy of Lichens and Allied Fungi
Opuscula Philolichenum, 11: 4-10. 2012. *pdf available online 3January2012 via (http://sweetgum.nybg.org/philolichenum/) An evolving phylogenetically based taxonomy of lichens and allied fungi 1 BRENDAN P. HODKINSON ABSTRACT. – A taxonomic scheme for lichens and allied fungi that synthesizes scientific knowledge from a variety of sources is presented. The system put forth here is intended both (1) to provide a skeletal outline of the lichens and allied fungi that can be used as a provisional filing and databasing scheme by lichen herbarium/data managers and (2) to announce the online presence of an official taxonomy that will define the scope of the newly formed International Committee for the Nomenclature of Lichens and Allied Fungi (ICNLAF). The online version of the taxonomy presented here will continue to evolve along with our understanding of the organisms. Additionally, the subfamily Fissurinoideae Rivas Plata, Lücking and Lumbsch is elevated to the rank of family as Fissurinaceae. KEYWORDS. – higher-level taxonomy, lichen-forming fungi, lichenized fungi, phylogeny INTRODUCTION Traditionally, lichen herbaria have been arranged alphabetically, a scheme that stands in stark contrast to the phylogenetic scheme used by nearly all vascular plant herbaria. The justification typically given for this practice is that lichen taxonomy is too unstable to establish a reasonable system of classification. However, recent leaps forward in our understanding of the higher-level classification of fungi, driven primarily by the NSF-funded Assembling the Fungal Tree of Life (AFToL) project (Lutzoni et al. 2004), have caused the taxonomy of lichen-forming and allied fungi to increase significantly in stability. This is especially true within the class Lecanoromycetes, the main group of lichen-forming fungi (Miadlikowska et al.
