Burdsall, Jr. Synopsis Fungorum 8 Fungiflora - Oslo - Norway A Nomenclatural Study of Armillaria and Armillariella species (Basidiomycotina, Tricholomataceae) by Thomas J. Volk & Harold H. Burdsall, Jr. Printed in Eko-trykk A/S, Førde, Norway Printing date: 1. August 1995 ISBN 82-90724-14-4 ISSN 0802-4966 A Nomenclatural Study of Armillaria and Armillariella species (Basidiomycotina, Tricholomataceae) by Thomas J. Volk & Harold H. Burdsall, Jr. Synopsis Fungorum 8 Fungiflora - Oslo - Norway 6 Authors address: Center for Forest Mycology Research Forest Products Laboratory United States Department of Agriculture Forest Service One Gifford Pinchot Dr. Madison, WI 53705 USA ABSTRACT Once a taxonomic refugium for nearly any white-spored agaric with an annulus and attached gills, the concept of the genus Armillaria has been clarified with the neotypification of Armillaria mellea (Vahl:Fr.) Kummer and its acceptance as type species of Armillaria (Fr.:Fr.) Staude. Due to recognition of different type species over the years and an extremely variable generic concept, at least 274 species and varieties have been placed in Armillaria (or in Armillariella Karst., its obligate synonym). Only about forty species belong in the genus Armillaria sensu stricto, while the rest can be placed in forty-three other modem genera. This study is based on original descriptions in the literature, as well as studies of type specimens and generic and species concepts by other authors. This publication consists of an alphabetical listing of all epithets used in Armillaria or Armillariella, with their basionyms, currently accepted names, and other obligate and facultative synonyms. -
Food Microbiology Fungal Spores: Highly Variable and Stress-Resistant Vehicles for Distribution and Spoilage
Food Microbiology 81 (2019) 2–11 Contents lists available at ScienceDirect Food Microbiology journal homepage: www.elsevier.com/locate/fm Fungal spores: Highly variable and stress-resistant vehicles for distribution and spoilage T Jan Dijksterhuis Westerdijk Fungal Biodiversity Institute, Uppsalalaan 8, 3584, Utrecht, the Netherlands ARTICLE INFO ABSTRACT Keywords: This review highlights the variability of fungal spores with respect to cell type, mode of formation and stress Food spoilage resistance. The function of spores is to disperse fungi to new areas and to get them through difficult periods. This Spores also makes them important vehicles for food contamination. Formation of spores is a complex process that is Conidia regulated by the cooperation of different transcription factors. The discussion of the biology of spore formation, Ascospores with the genus Aspergillus as an example, points to possible novel ways to eradicate fungal spore production in Nomenclature food. Fungi can produce different types of spores, sexual and asexually, within the same colony. The absence or Development Stress resistance presence of sexual spore formation has led to a dual nomenclature for fungi. Molecular techniques have led to a Heat-resistant fungi revision of this nomenclature. A number of fungal species form sexual spores, which are exceptionally stress- resistant and survive pasteurization and other treatments. A meta-analysis is provided of numerous D-values of heat-resistant ascospores generated during the years. The relevance of fungal spores for food microbiology has been discussed. 1. The fungal kingdom molecules, often called “secondary” metabolites, but with many pri- mary functions including communication or antagonism. However, Representatives of the fungal kingdom, although less overtly visible fungi can also be superb collaborators as is illustrated by their ability to in nature than plants and animals, are nevertheless present in all ha- form close associations with members of other kingdoms. -

<I>Byssochlamys</I> and Its <I>Paecilomyces</I&G
Persoonia 22, 2009: 14–27 www.persoonia.org RESEARCH ARTICLE doi:10.3767/003158509X418925 Polyphasic taxonomy of the heat resistant ascomycete genus Byssochlamys and its Paecilomyces anamorphs R.A. Samson1, J. Houbraken1, J. Varga1,2, J.C. Frisvad 3 Key words Abstract Byssochlamys and related Paecilomyces strains are often heat resistant and may produce mycotoxins in contaminated pasteurised foodstuffs. A comparative study of all Byssochlamys species was carried out using a Byssochlamys polyphasic approach to find characters that differentiate species and to establish accurate data on potential myco emodin toxin production by each species. Phylogenetic analysis of the ITS region, parts of the -tubulin and calmodulin Eurotiales β genes, macro and micromorphological examinations and analysis of extrolite profiles were applied. Phylogenetic extrolites analyses revealed that the genus Byssochlamys includes nine species, five of which form a teleomorph, i.e. B. fulva, heat resistance B. lagunculariae, B. nivea, B. spectabilis and B. zollerniae, while four are asexual, namely P. brunneolus, P. divari mycophenolic acid catus, P. formosus and P. saturatus. Among these, B. nivea produces the mycotoxins patulin and byssochlamic Paecilomyces acid and the immunosuppressant mycophenolic acid. Byssochlamys lagunculariae produces byssochlamic acid patulin and mycophenolic acid and thus chemically resembles B. nivea. Some strains of P. saturatus produce patulin and brefeldin A, while B. spectabilis (anamorph P. variotii s.s.) produces viriditoxin. Some micro- and macromorphologi- cal characters are valuable for identification purposes, including the shape and size of conidia and ascospores, presence and ornamentation of chlamydospores, growth rates on MEA and CYA and acid production on CREA. A dichotomous key is provided for species identification based on phenotypical characters. -

Armillaria This is one of the few genera of the Sarcoscyphaceae not associated with plant material – wood or leaves. The sclerotium is symbiosis composed of hyphae of both Armillaria species and Wynnea species. To verify the existence of Armillaria species in the sclerotia of sclerotium those Wynnea species not previously examined and to fully understand the structure and nature of the sclerotium, molecular data Wynnea and morphological characters were analyzed. Using nuclear ITS rDNA sequences the Armillaria species co-occurring with Wynnea species were identified from all examined material. TheseArmillaria symbionts fall into two main Armillaria groups – the A. gallica- nabsnona-calvescens group and the A. mellea group.

Koch1 and Joshua R. Herr1,2,* 1Department of Plant Pathology, University of Nebraska, Lincoln, NE 68503, USA; 2Center for Plant Science Innovation, University of Nebraska, Lincoln, NE 68588, USA; *Correspondence: Joshua R. Herr ([email protected]) ABSTRACT Armillaria is a globally distributed fungal genus most notably recognized as economically important plant pathogens that are found predominantly in forest and agronomic systems. Armillaria has more recently received attention for ecologically diverse roles as woody plant decomposers and as mycorrhizal symbionts with specific plants. Previous phylogenetic analyses suggest that around 50 species are recognized globally. Despite this previous work, no studies have analyzed the global species richness and distribution of the genus using data derived from fungal community sequencing datasets. In order to assess the global diversity and species richness of Armillaria, we mined publicly available sequencing datasets derived from numerous primer pairs for the ribosomal operon. Our estimates reveal that species richness ranges from 50 to 60 species, depending on which marker is used. Eastern Asia represents the biogeographic region with the highest species richness. We also assess the overlap of species across geographic regions and propose some hypotheses regarding the drivers of variability in species diversity and richness between different biogeographic regions. -
