Tuhinga 16: 59–91 Copyright © Te Papa Museum of New Zealand (2005) The lichen genus Physcia (Schreb.) Michx (Physciaceae: Ascomycota) in New Zealand D. J. Galloway1 and R. Moberg 2 1 Landcare Research, New Zealand Ltd, Private Bag 1930, Dunedin, New Zealand ([email protected]) 2 Botany Section (Fytoteket), Museum of Evolution, Evolutionary Biology Centre, Uppsala University, Norbyvägen 16, SE-752 36 Uppsala, Sweden ABSTRACT: Fourteen species of the lichen genus Physcia (Schreb.) Michx are recognised in the New Zealand mycobiota, viz: P. adscendens, P. albata, P. atrostriata, P. caesia, P. crispa, P. dubia, P. erumpens, P. integrata, P. jackii, P. nubila, P. poncinsii, P. tribacia, P. trib- acoides, and P. undulata. Descriptions of each taxon are given, together with a key and details of biogeography, chemistry, distribution, and ecology. Physcia tenuisecta Zahlbr., is synonymised with Hyperphyscia adglutinata, and Physcia stellaris auct. is deleted from the New Zealand mycobiota. Physcia atrostriata, P. dubia, P. integrata, and P. nubila are recorded from New Zealand for the first time. A list of excluded taxa is appended. KEYWORDS: lichens, New Zealand lichens, Physcia, atmospheric pollution, biogeography. Introduction genera with c. 860 species presently known (Kirk et al. 2001), and was recently emended to include taxa having: Species of Physcia (Schreb.) Michx, are foliose, lobate, Lecanora-type asci; a hyaline hypothecium; and ascospores loosely to closely appressed lichens, with a whitish, pale with distinct wall thickenings or of Rinodella-type (Helms greenish, green-grey to dark-grey upper surface (not dark- et al. 2003). Physcia is a widespread, cosmopolitan genus ening, or colour only little changed, when moistened). -

Their continued management level support has been essential to the development of this monitoring program. Lichen collections and field work: Field work was largely completed by the authors. Mary Muller contributed many lichens to the inventory collected in her capacity as Regional Botanist during the past 10 years. Field work was aided by Sarah Ryll of the Stikine Area, Elizabeth Wilder and Walt Tulecke of Antioch College, and Bill Pawuk, Stikine Area ecologist. Lichen identifications: Help with the lichen identifications was given by Irwin Brodo of the Canadian National Museum, John Thomson of the University of Wisconsin at Madison, Pak Yau Wong of the Canadian National Museum, and Bruce McCune at Oregon State University. -

Endolichenic fungi (ELF) are one of the inhabitants living in lichen thalli, and have potential ecological and industrial applications due to their various secondary metabolites. As the function of endophytic fungi on the plant ecology and ecosystem sustainability, ELF may have an influence on the lichen diversity and the ecosystem, functioning similarly to the influence of endophytic fungi on plant ecology and ecosystem sustainability, which suggests the importance of understanding the diversity and community pattern of ELF. In this study, we investigated the diversity and the factors influencing the community structure of ELF in Jeju Island, South Korea by analyzing 619 fungal isolates from 79 lichen samples in Jeju Island. A total of 112 ELF species was identified and the most common species belonged to Xylariales in Sordariomycetes. -

Comparison of Invertebrates and Lichens Between Young and Ancient
Comparison of invertebrates and lichens between young and ancient yew trees Bachelor agro & biotechnology Specialization Green management 3th Internship report / bachelor dissertation Student: Clerckx Jonathan Academic year: 2014-2015 Tutor: Ms. Joos Isabelle Mentor: Ms. Birch Katherine Natural England: Kingley Vale NNR Downs Road PO18 9BN Chichester www.naturalengland.org.uk Comparison of invertebrates and lichens between young and ancient yew trees. Natural England: Kingley Vale NNR Foreword My dissertation project and internship took place in an ancient yew woodland reserve called Kingley Vale National Nature Reserve. Kingley Vale NNR is managed by Natural England. My dissertation deals with the biodiversity in these woodlands. During my stay in England I learned many things about the different aspects of nature conservation in England. First of all I want to thank Katherine Birch (manager of Kingley Vale NNR) for giving guidance through my dissertation project and for creating lots of interesting days during my internship. I want to thank my tutor Isabelle Joos for suggesting Kingley Vale NNR and guiding me during the year. I thank my uncle Guido Bonamie for lending me his microscope and invertebrate books and for helping me with some identifications of invertebrates. I thank Lies Vandercoilden for eliminating my spelling and grammar faults. Thanks to all the people helping with identifications of invertebrates: Guido Bonamie, Jon Webb, Matthew Shepherd, Bryan Goethals. And thanks to the people that reacted on my posts on the Facebook page: Lichens connecting people! I want to thank Catherine Slade and her husband Nigel for being the perfect hosts of my accommodation in England. -
Nine New Lichen Species and 64 New Records from Sri Lanka

Weerakoon: Integrative Research Centre, Department of Science & Education, Field Museum of Natural History, Chicago, USA A. Aptroot: ABL Herbarium, G.v.d.Veenstraat 107, NL-3762 XK Soest, The Netherlands; Email: [email protected] Abstract The lichen diversity of ten forest sites representing different geographical regions in Sri Lanka was investigated. In total, c. 1500 specimens of c. 400 species were recorded of the evaluated groups (all except the Graphidaceae and a few foliose groups). The following new species are described: Astrothelium conjugatum, Heterodermia fragmentata, Lecanactis minu- tissima, Megalotremis cylindrica, Porina microtriseptata, Porina monilisidiata, Psoroglaena spinosa, Pyrenula multicolo- rata, and Schistophoron muriforme. A further 64 species are reported for the first time from Sri Lanka, including 30 new records for the Indian subcontinent and eight new to Asia. Key words: Astrothelium, Heterodermia, Lecanactis, Megalotremis, Porina, Psoroglaena, Pyrenula, Schistophoron Introduction The island of Sri Lanka harbours a diverse flora and fauna, including species that are absent from India (J. & J. de Vlas 2008; Jayasinghe 2015; Wickramasinghe 2014, Harrison & Worfolk 2011; Meegaskubura et al. 2010). This is also true with regard to its lichen biota, the study of which has only recently begun systematically (Weerakoon 2013 & 2015; Weerakoon et al. 2012a, b & c; Weerakoon & Aptroot 2013 & 2014; Weerakoon et al. -
New Species and New Records of American Lichenicolous Fungi
DHerzogiaIEDERICH 16: New(2003): species 41–90 and new records of American lichenicolous fungi 41 New species and new records of American lichenicolous fungi Paul DIEDERICH Abstract: DIEDERICH, P. 2003. New species and new records of American lichenicolous fungi. – Herzogia 16: 41–90. A total of 153 species of lichenicolous fungi are reported from America. Five species are described as new: Abrothallus pezizicola (on Cladonia peziziformis, USA), Lichenodiplis dendrographae (on Dendrographa, USA), Muellerella lecanactidis (on Lecanactis, USA), Stigmidium pseudopeltideae (on Peltigera, Europe and USA) and Tremella lethariae (on Letharia vulpina, Canada and USA). Six new combinations are proposed: Carbonea aggregantula (= Lecidea aggregantula), Lichenodiplis fallaciosa (= Laeviomyces fallaciosus), L. lecanoricola (= Laeviomyces lecanoricola), L. opegraphae (= Laeviomyces opegraphae), L. pertusariicola (= Spilomium pertusariicola, Laeviomyces pertusariicola) and Phacopsis fusca (= Phacopsis oxyspora var. fusca). The genus Laeviomyces is considered to be a synonym of Lichenodiplis, and a key to all known species of Lichenodiplis and Minutoexcipula is given. The genus Xenonectriella is regarded as monotypic, and all species except the type are provisionally kept in Pronectria. A study of the apothecial pigments does not support the distinction of Nesolechia and Phacopsis. The following 29 species are new for America: Abrothallus suecicus, Arthonia farinacea, Arthophacopsis parmeliarum, Carbonea supersparsa, Coniambigua phaeographidis, Diplolaeviopsis
