Under suitable conditions, however, it is also easily degradable as part of the biological cycle. The processes of decomposition by fungi, and measures for protection against them, have been studied for quite a long time. The resulting knowledge on the causes and effects of wood degradation can hardly be overlooked. For more than 30 years, Olaf Schmidt has investigated the causes and effects of wood degradation by fungi and bacteria. Pioneering contributions have also been made in several fields, such as wood-inhabiting bacteria and molecular methods for fungal identification. Laboratory work is accompanied by teaching the field of wood deterioration by microorganisms, thus contributing to the broad spectrum of information accumulated. “WoodandTreeFungi”byOlafSchmidtpresentsthemostcomprehensive treatise on the fundamentals, causes, and consequences of decomposition of wood as well as measures for its prevention. The 1,400 references give an overlook of the vast amount of information evaluated. For a long time to come this book will be the competent source of knowledge about the fascinating interactions between wood and microorganisms. Walter Liese Preface This book is the updated revision of the German edition “Holz- und Baumpilze” from 1994. Errors were corrected and new results were included. Particularly the chapter “Identification” was supplemented by molecular techniques. I re- alize that a one-author book on a relatively broad topic must include errors and also may have ignored recent literature. Strictly speaking, one should only write about things that they have experienced themselves, in the case of point this only concerns some aspects of bacteria and those fungi which inhabit the xylem of dead wood. Thus, current “secondary literature” was used for those chapters that are “on the edge” of my own research interest. For better readability, the authors of fungal names are not mentioned in the text, but summarized in an appendix. Fungal synonyms are also not given. These are available from Index Fungorum (www.indexfungorum.org/names/ names.asp). Fungal names cited from (older) publications were transferred to the current version.

  • Dying Cedar Hedges —What Is the Cause?
    Points covered in this factsheet Symptoms Planting problems Physiological effects Environmental, Soil and Climate factors Insect, Disease and Vertebrate agents Dying Cedar Hedges —What Is The Cause? Attractive and normally trouble free, cedar trees can be great additions to the landscape. Dieback of cedar hedging in the landscape is a common prob- lem. In most cases, it is not possible to pinpoint one single cause. Death is usually the result of a combination of envi- ronmental stresses, soil factors and problems originating at planting. Disease, insect or animal injury is a less frequent cause. Identifying The Host Certain species of cedar are susceptible to certain problems, so identifying the host plant can help to identify the cause and whether a symptom is an issue of concern or is normal for that plant. The most common columnar hedging cedars are Thuja plicata (Western Red Cedar - native to the West Coast) and Thuja occidentalis (American Arborvitae or Eastern White ICULTURE, PLANT HEALTH UNIT Cedar). Both species are often called arborvitae. Common varieties of Western Red ce- dar are ‘Emerald Giant’, ‘Excelsa’ and Atrovirens’. ‘Smaragd’ and ‘Pyramidalis’ are com- mon varieties of Eastern White cedar hedging. Species of Cupressus (Cypress), Chamaecyparis nootkatensis (Yellow Cedar or False Cypress) and Chamaecyparis law- soniana (Port Orford Cedar or lawsom Cypress) are also used in hedging. Symptoms The pattern of symptom development/distribution can provide a clue to whether the prob- lem is biotic (infectious) or abiotic (non-infectious). Trees often die out in a group, in one section of the hedge, or at random throughout the hedge.

GRIFFITH3, DILUKA PEIRIS1 1School of Life Sciences, University of Westminster, 115 New Cavendish Street, London, W1M 8JS 2Natural History Museum, Cromwell Road, London, SW7 5BD 3Institute of Biological Environmental and Rural Sciences, University of Aberystwyth, SY23 3DD Corresponding author, e-mail: [email protected] ABSTRACT The results of four five-day field surveys of fungi carried out yearly on Lundy from 2004-08 are reported and the results compared with the previous survey by ourselves in 2003 and to records made prior to 2003 by members of the LFS. 240 taxa were identified of which 159 appear to be new records for the island. Seasonal distribution, habitat and resource preferences are discussed. Keywords: Fungi, ecology, biodiversity, conservation, grassland INTRODUCTION Hedger & George (2004) published a list of 108 taxa of fungi found on Lundy during a five-day survey carried out in October 2003. They also included in this paper the records of 95 species of fungi made from 1970 onwards, mostly abstracted from the Annual Reports of the Lundy Field Society, and found that their own survey had added 70 additional records, giving a total of 156 taxa. They concluded that further surveys would undoubtedly add to the database, especially since the autumn of 2003 had been exceptionally dry, and as a consequence the fruiting of the larger fleshy fungi on Lundy, especially the grassland species, had been very poor, resulting in under-recording. Further five-day surveys were therefore carried out each year from 2004-08, three in the autumn, 8-12 November 2004, 4-9 November 2007, 3-11 November 2008, one in winter, 23-27 January 2006 and one in spring, 9-16 April 2005.

  • The Use of Algae and Fungi for Removal of Pharmaceuticals by Bioremediation and Biosorption Processes: a Review
    Review The Use of Algae and Fungi for Removal of Pharmaceuticals by Bioremediation and Biosorption Processes: A Review Andreia Silva, Cristina Delerue-Matos, Sónia A. Figueiredo and Olga M. Freitas * REQUIMTE/LAQV, Instituto Superior de Engenharia do Porto, Rua Dr. António Bernardino de Almeida 431, 4200-072 Porto, Portugal * Correspondence: [email protected] Received: 3 July 2019; Accepted: 25 July 2019; Published: 27 July 2019 Abstract: The occurrence and fate of pharmaceuticals in the aquatic environment is recognized as one of the emerging issues in environmental chemistry. Conventional wastewater treatment plants (WWTPs) are not designed to remove pharmaceuticals (and their metabolites) from domestic wastewaters. The treatability of pharmaceutical compounds in WWTPs varies considerably depending on the type of compound since their biodegradability can differ significantly. As a consequence, they may reach the aquatic environment, directly or by leaching of the sludge produced by these facilities. Currently, the technologies under research for the removal of pharmaceuticals, namely membrane technologies and advanced oxidation processes, have high operation costs related to energy and chemical consumption. When chemical reactions are involved, other aspects to consider include the formation of harmful reaction by-products and the management of the toxic sludge produced. Research is needed in order to develop economic and sustainable treatment processes, such as bioremediation and biosorption. The use of low-cost materials, such as biological matrices (e.g., algae and fungi), has advantages such as low capital investment, easy operation, low operation costs, and the non-formation of degradation by-products. An extensive review of existing research on this subject is presented.

This large class of organic hydrocarbons is distributed among all cellular organisms, including fungi. The different classes of terpenes produced by fungi are mono, sesqui, di- and triterpenes, although triterpene ergosterol is the main sterol identified in cell membranes of these organisms. The availability of genomic data from members in the Ceratocystidaceae enabled the detection and characterization of the genes encoding the enzymes in the mevalonate and ergosterol biosynthetic pathways. Using Citation: Sayari, M.; van der Nest, a bioinformatics approach, fungal orthologs of sterol biosynthesis genes in nine different species M.A.; Steenkamp, E.T.; Rahimlou, S.; of the Ceratocystidaceae were identified.

  • Phylogenetic Classification of Trametes
    TAXON 60 (6) • December 2011: 1567–1583 Justo & Hibbett • Phylogenetic classification of Trametes SYSTEMATICS AND PHYLOGENY Phylogenetic classification of Trametes (Basidiomycota, Polyporales) based on a five-marker dataset Alfredo Justo & David S. Hibbett Clark University, Biology Department, 950 Main St., Worcester, Massachusetts 01610, U.S.A. Author for correspondence: Alfredo Justo, [email protected] Abstract: The phylogeny of Trametes and related genera was studied using molecular data from ribosomal markers (nLSU, ITS) and protein-coding genes (RPB1, RPB2, TEF1-alpha) and consequences for the taxonomy and nomenclature of this group were considered. Separate datasets with rDNA data only, single datasets for each of the protein-coding genes, and a combined five-marker dataset were analyzed. Molecular analyses recover a strongly supported trametoid clade that includes most of Trametes species (including the type T. suaveolens, the T. versicolor group, and mainly tropical species such as T. maxima and T. cubensis) together with species of Lenzites and Pycnoporus and Coriolopsis polyzona. Our data confirm the positions of Trametes cervina (= Trametopsis cervina) in the phlebioid clade and of Trametes trogii (= Coriolopsis trogii) outside the trametoid clade, closely related to Coriolopsis gallica. The genus Coriolopsis, as currently defined, is polyphyletic, with the type species as part of the trametoid clade and at least two additional lineages occurring in the core polyporoid clade. In view of these results the use of a single generic name (Trametes) for the trametoid clade is considered to be the best taxonomic and nomenclatural option as the morphological concept of Trametes would remain almost unchanged, few new nomenclatural combinations would be necessary, and the classification of additional species (i.e., not yet described and/or sampled for mo- lecular data) in Trametes based on morphological characters alone will still be possible.

Mycosphere 8(7), 878–885, Doi 10.5943/mycosphere/8/7/4 Abstract A new species, Antrodia monomitica sp. nov., is described and illustrated from China based on morphological characters and molecular evidence. It is characterized by producing annual, fragile and nodulose basidiomata, a monomitic hyphal system with clamp connections on generative hyphae, hyaline, thin-walled and fusiform to mango-shaped basidiospores (6–7.5 × 2.3– 3 µm), and causing a typical brown rot. In phylogenetic analysis inferred from ITS and nLSU rDNA sequences, the new species forms a distinct lineage in the Antrodia s. l., and has a close relationship with A. oleracea.

These bers of the antrodia clade were investigated with studies also established that some of the genera are molecular data from two nuclear ribosomal DNA not monophyletic and several modifications have regions, LSU and ITS. A total of 123 species been proposed: the segregation of Antrodia s.l.
