  • The Lichens' Microbiota, Still a Mystery?
    fmicb-12-623839 March 24, 2021 Time: 15:25 # 1 REVIEW published: 30 March 2021 doi: 10.3389/fmicb.2021.623839 The Lichens’ Microbiota, Still a Mystery? Maria Grimm1*, Martin Grube2, Ulf Schiefelbein3, Daniela Zühlke1, Jörg Bernhardt1 and Katharina Riedel1 1 Institute of Microbiology, University Greifswald, Greifswald, Germany, 2 Institute of Plant Sciences, Karl-Franzens-University Graz, Graz, Austria, 3 Botanical Garden, University of Rostock, Rostock, Germany Lichens represent self-supporting symbioses, which occur in a wide range of terrestrial habitats and which contribute significantly to mineral cycling and energy flow at a global scale. Lichens usually grow much slower than higher plants. Nevertheless, lichens can contribute substantially to biomass production. This review focuses on the lichen symbiosis in general and especially on the model species Lobaria pulmonaria L. Hoffm., which is a large foliose lichen that occurs worldwide on tree trunks in undisturbed forests with long ecological continuity. In comparison to many other lichens, L. pulmonaria is less tolerant to desiccation and highly sensitive to air pollution. The name- giving mycobiont (belonging to the Ascomycota), provides a protective layer covering a layer of the green-algal photobiont (Dictyochloropsis reticulata) and interspersed cyanobacterial cell clusters (Nostoc spec.). Recently performed metaproteome analyses Edited by: confirm the partition of functions in lichen partnerships.

  • 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.

  • Revision of the Lichen Genus Aspicilia in Sweden
    SWEDISH TAXONOMY INITIATIVE RESEARCH REPORT Project period: 2005–2007 Anders Nordin Museum of Evolution, Uppsala University LICHENS: Revision of the lichen genus Aspicilia in Sweden The Swedish representatives of the lichen genus Aspicilia have been revised. The species have been studied in the field in different parts of the country, and material has been collected, altogether c. 500 samples. Herbarium material from Uppsala (UPS) and a number of additional herbaria has also been studied. Total DNA has been extracted from c. 250 collections not older than 10 years. Morphology and chemistry have been studied with traditional methods, including HPLC. Of the 74 species recorded in Sweden only about 45 remain, including a number of undescribed species, two of which have been described (Nordin et al. 2011). The decreased number is a result of synonymizations (Nordin et al. 2007, Nordin 2013, 2015) and disclosure of incorrect determinations, and one species, Aspicilia moenium, is not an Aspicilia but belongs in Acarosporaceae (Nordin et al. 2009). From the extracted DNA, ITS sequences have been produced from all samples, and from a reduced number also nuLSU and mtSSU sequences. The ITS sequences have been used for evaluation of species delimitations. Sequences from specimens resembling the types of the species known from one or a few collections have been of particular importance. ITS sequences have also been used for phylogenetic analyses. The groups resulting from these are robust and are largely supported by analyses of the nuLSU and mtSSU sequences. The latter were used in a study of the phylogeny at family level (Nordin et al.

  • A New Species of Aspicilia (Megasporaceae), with a New Lichenicolous Sagediopsis (Adelococcaceae), from the Falkland Islands
    The Lichenologist (2021), 53, 307–315 doi:10.1017/S0024282921000244 Standard Paper A new species of Aspicilia (Megasporaceae), with a new lichenicolous Sagediopsis (Adelococcaceae), from the Falkland Islands Alan M. Fryday1 , Timothy B. Wheeler2 and Javier Etayo3 1Department of Plant Biology, Michigan State University, East Lansing, Michigan 48824, USA; 2Division of Biological Sciences, University of Montana, Missoula, Montana 59801, USA and 3Navarro Villoslada 16, 3° dcha., 31003 Pamplona, Navarra, Spain Abstract The new species Aspicilia malvinae is described from the Falkland Islands. It is the first species of Megasporaceae to be discovered on the islands and only the seventh to be reported from South America. It is distinguished from other species of Aspicilia by the unusual secondary metabolite chemistry (hypostictic acid) and molecular sequence data. The collections of the new species support two lichenicolous fungi: Endococcus propinquus s. lat., which is new to the Falkland Islands, and a new species of Sagediopsis with small perithecia and 3-septate ascospores c. 18–20 × 4–5 μm, which is described here as S. epimalvinae. A total of 60 new DNA sequences obtained from species of Megasporaceae (mostly Aspicilia) are also introduced. Key words: DNA sequences, Endococcus, Lecanora masafuerensis, lichen, southern South America, southern subpolar region (Accepted 18 March 2021) Introduction Materials and Methods Species of Megasporaceae Lumbsch et al. are surprisingly scarce Morphological methods in the Southern Hemisphere. Whereas 97 species are known Gross morphology was examined under a dissecting microscope from North America (Esslinger 2019), 104 from Russia and apothecial characteristics by light microscopy (compound (Urbanavichus 2010), 40 from Svalbard (Øvstedal et al.

  • Opuscula Philolichenum, 6: 1-XXXX
    Opuscula Philolichenum, 15: 56-81. 2016. *pdf effectively published online 25July2016 via (http://sweetgum.nybg.org/philolichenum/) Lichens, lichenicolous fungi, and allied fungi of Pipestone National Monument, Minnesota, U.S.A., revisited M.K. ADVAITA, CALEB A. MORSE1,2 AND DOUGLAS LADD3 ABSTRACT. – A total of 154 lichens, four lichenicolous fungi, and one allied fungus were collected by the authors from 2004 to 2015 from Pipestone National Monument (PNM), in Pipestone County, on the Prairie Coteau of southwestern Minnesota. Twelve additional species collected by previous researchers, but not found by the authors, bring the total number of taxa known for PNM to 171. This represents a substantial increase over previous reports for PNM, likely due to increased intensity of field work, and also to the marked expansion of corticolous and anthropogenic substrates since the site was first surveyed in 1899. Reexamination of 116 vouchers deposited in MIN and the PNM herbarium led to the exclusion of 48 species previously reported from the site. Crustose lichens are the most common growth form, comprising 65% of the lichen diversity. Sioux Quartzite provided substrate for 43% of the lichen taxa collected. Saxicolous lichen communities were characterized by sampling four transects on cliff faces and low outcrops. An annotated checklist of the lichens of the site is provided, as well as a list of excluded taxa. We report 24 species (including 22 lichens and two lichenicolous fungi) new for Minnesota: Acarospora boulderensis, A. contigua, A. erythrophora, A. strigata, Agonimia opuntiella, Arthonia clemens, A. muscigena, Aspicilia americana, Bacidina delicata, Buellia tyrolensis, Caloplaca flavocitrina, C. lobulata, C.

Teuvoa saxicola differs from other Teuvoa species by its saxicolous habitat, and its yellow brown, thick thallus. Teuvoa alpina resembles T. junipericola from western USA, but differs by its smaller ascospores and its higher altitude habitat. The morphological characters of the new species are illustrated. New material is described of T. tibetica, the only species previously recorded from China. The morphological and phylogenetic characteristics of the three species are discussed and compared with similar taxa. Key words—Megasporaceae, Pertusariales, Lobothallia, lichens, taxonomy Introduction The lichen genus Teuvoa Sohrabi & S.D. Leav. (Pertusariales, Megasporaceae) was established based on the analysis of molecular sequence data and morphological characters (Sohrabi & al. 2013). The lichen family Megasporaceae has six genera: Aspicilia, Circinaria, Lobothallia, Megaspora, Sagedia, and Teuvoa (Schmitt & al. 2006, Lumbsch & al. 2007, Nordin & al. 2010, Sohrabi & al. 2013). Phylogenetic analysis by Sohrabi & al. (2013) supports Teuvoa as the sister group to Lobothallia. Teuvoa is characterized by its 8-spored asci, absence of extrolites, rather short conidia and ascospores, lack of a subhypothecial algal layer, and different substratum preferences (Sohrabi & al. 2013). Worldwide, there are three described Teuvoa species: the terricolous T.

Acarospora superfusa is confirmed as occurring in North America. Biatorella rappii is placed in synonymy with Ramonia microspora. Key words— Appalachian Mountains, Magnusson, Sonoran Desert, SE coastal plain. 1. Acarospora complanata H. Magn., Svensk. Bot. Tidskr. 18: 332. 1924. Type: France. Provence-Alpes-Côte D’azur: Var Dist., Massif volcanique de la Courtine, pres Ollisules, 1923, de Crozals (hb. B. de Lesd.[n.v.-presumed destroyed], holotype; UPS! isotype). Acarospora complanata was described from France (Magnusson 1924) and Magnusson recognized it as occurring in Africa and Mexico (Magnusson 1929, 1956). The species forms a brown areolate orbicular thallus with inconspicuous immersed apothecia and an effigurate margin with narrow lobes, a hymenium 80–90 μm high, paraphyses at mid-height mostly 2–2.5 μm in diameter, and a cortex that contains gyrophoric and lecanoric acids (KC+ pink). For a fuller description see Magnusson (1929). Morphologically, the species does not appear related to A. molybdina (Wahlenb.) Trevis, A. macrocyclos Vain., or A.
