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. -

MycoKeys 48: 55–65. https://doi.org/10.3897/mycokeys.48.33001 Abstract Biatora alnetorum S. Ekman & Tønsberg, a lichenised ascomycete in the family Ramalinaceae (Lecano- rales, Lecanoromycetes), is described as new to science. It is distinct from other species of Biatora in the combination of mainly three-septate ascospores, a crustose thallus forming distinctly delimited soralia that develop by disintegration of convex pustules and the production of atranorin in the thallus and apothecia. The species is known from the Pacific Northwest of North America, where it inhabits the smooth bark of Alnus alnobetula subsp. sinuata and A. rubra. Biatora alnetorum is also a new host for the lichenicolous ascomycete Sclerococcum toensbergii Diederich. Keywords Biatora flavopunctata, Biatora pallens, Lecania, BAli-Phy Introduction During field work in the Pacific Northwest of the United States and Canada in 1995– 2018, the second author came across a distinct crustose and sorediate lichen on the smooth bark of alders. -

The check-lists include 172 species of lichens and 51 species of vascular plants. Several species rare in Svalbard and in the Arctic were discovered: Candelariella borealis was new to Svalbard. 51 lichen species were newly recorded on Nordaustlandet and 131 lichen species were observed in the Duvefjorden area for the first time. Among lichen species rare in Svalbard and in the Arctic the following can be mentioned: Caloplaca magni-filii, C. nivalis, Lecidea silacea, Phaeophyscia nigricans, Polyblastia gothica, Protothelenella sphinctrinoidella, Rinodina conradii, Stenia geophana, and Tetramelas pulverulentus. Two species of vascular plants, Saxifraga svalbardensis and S. hyperborea, were found new to the Duvefjorden area. The investigated flora is represented mostly by species widespread in Svalbard and in the Arctic. Although Duvefjorden area is situated in the northernmost part of Svalbard, its flora is characterized by relatively high diversity of vascular plants and lichens. -

Czeppe Department of Polar Research and Documentation, Institute of Botany, Jagiellonian University, Kopernika 27, 31-501 Kraków, Poland <[email protected]>, <[email protected]> 2 Centre for Polar Studies, University of Silesia, Będzińska 60, 41-200 Sosnowiec, Poland <[email protected]> * corresponding author Abstract: The rapidly changing Arctic provides excellent opportunities for investigat- ing primary succession on freshly deglaciated areas. Research on the Gåsbreen foreland (S Spitsbergen) traced the succession of particular groups of organisms and species, particularly lichens and bryophytes, and determined the effect of selected abiotic fac- tors on this succession. Fieldwork in 2008, employed a continuous linear transect of phytosociological relevés (1 m2) along the foreland. Data analysis allowed to distinguish five different succession stages and three types of colonisers. Canonical correspondence analysis and a permutation test showed that distance from the front of the glacier and fine grain material in the substrate mostly influenced the distribution and abundance of vegetation, and the steepness of the moraine hills affected the colonisation process, mainly in the older part of the marginal zone. Key words: Arctic, colonisation, glacier, lichens, bryophytes, vascular plants. Introduction Arctic regions offer perfect opportunities for studying primary succession processes on freshly deglaciated areas (Frenot et al. 1998; Jorgenson et al. 2015). Areas which are exposed from retreating glaciers are successively colonised by different groups of organisms such as cyanobacteria, lichens, bryophytes and vascular plants. -

Pino-Bodas1,2, M.P. Zhurbenko3, S. Stenroos1 Key words Abstract Though most of the lichenicolous fungi belong to the Ascomycetes, their phylogenetic placement based on molecular data is lacking for numerous species. In this study the phylogenetic placement of 19 species of cladoniicolous species lichenicolous fungi was determined using four loci (LSU rDNA, SSU rDNA, ITS rDNA and mtSSU). The phylogenetic Pilocarpaceae analyses revealed that the studied lichenicolous fungi are widespread across the phylogeny of Lecanoromycetes. Protothelenellaceae One species is placed in Acarosporales, Sarcogyne sphaerospora; five species in Dactylosporaceae, Dactylo Scutula cladoniicola spora ahtii, D. deminuta, D. glaucoides, D. parasitica and Dactylospora sp.; four species belong to Lecanorales, Stictidaceae Lichenosticta alcicorniaria, Epicladonia simplex, E. stenospora and Scutula epiblastematica. The genus Epicladonia Stictis cladoniae is polyphyletic and the type E. sandstedei belongs to Leotiomycetes. Phaeopyxis punctum and Bachmanniomyces uncialicola form a well supported clade in the Ostropomycetidae. Epigloea soleiformis is related to Arthrorhaphis and Anzina. Four species are placed in Ostropales, Corticifraga peltigerae, Cryptodiscus epicladonia, C. galaninae and C. cladoniicola -
