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.

  • Appendix: Orchid Potting Mixtures - an Abridged Historical Review 1
    Appendix: Orchid potting mixtures - An abridged historical review 1 T. J. SHEEHAN Introduction There is little doubt that potting media development over time has been the salvation of orchid growers (Bomba, 1975). When epiphytic orchids were first introduced into England and other European countries in the 18th century growers could not envision plants growing in anything but soil. '"Peat and loam' were good for everything and frequently became the mass murderers of the first generation of epiphytic orchids," Hooker is believed to have said around the end of the 19th century; England had become the graveyard of tropical orchids. Undoubtedly this was in reference to the concern individuals were having over the potting media problems. This problem also drew the attention of such noted individuals as John Lindley and Sir Joseph Paxton, as well as the Gardener's Chronicle, who noted that "The Rule of Thumb" had nothing to say about orchid growing; it was only effective in orchid killing (Bomba 1975). Fortunately, the ingenuity of growers solved the problem as innovative potting mixes evolved over the years. After visiting a number of orchid growing establishments it immediately becomes obvious to any orchid grower, professional or hobbyist, that orchids, both epiphytic and terrestrial, will grow in a wide variety of media. It has often been stated that epiphytic orchids can be grown in any medium except soil as long as watering and fertilization are adjusted to fit the mix being used. Ter­ restrial orchids seem to thrive in any medium that contains 40% or more organic matter. Reading cultural recommendations from the early days of orchid growing is most interesting and highly recommended.

(2003): Distribution and ecology of Armillaria species in some habitats of southern Moravia, Czech Republic. - Czech Mycol. 55: 173-186 In forest ecosystems of southern Moravia, five species of annulate A rm illaria species and the exannulate species Armillaria socialis were observed. Armillaria ostoyae shows its ecological optimum in the forest type group Querceto-Fagetum where it represents an important parasite of spruce. Armillaria gallica is a dominant species of floodplain forests and thermophilic oak communities where A . ostoyae is lacking. Armillaria mellea occurs on broadleaved species and fruit trees. Armillaria cepistipes and A. borealis were detected in the Drahanská vrchovina Highlands only, A. socialis occurs rarely on stumps and bases of dead oak trees in a hard-wooded floodplain forest along the Dyje river. It is one of the northernmost localities in Europe. A rm illaria spp. were identified in 79 hosts, 33 of which were coniferous species. The main role of A rm illaria spp. consists in the decomposition of wood in soil (stumps, roots) and in the species spectrum regulation in the course of succession. Key words: Armillaria, root rots, hosts, ecology Jankovský L.

  • Armillaria Root Rot Fungi Host Single-Stranded RNA Viruses
    www.nature.com/scientificreports OPEN Armillaria root rot fungi host single‑stranded RNA viruses Riikka Linnakoski1,5, Suvi Sutela1,5, Martin P. A. Coetzee2, Tuan A. Duong2, Igor N. Pavlov3,4, Yulia A. Litovka3,4, Jarkko Hantula1, Brenda D. Wingfeld2 & Eeva J. Vainio1* Species of Armillaria are distributed globally and include some of the most important pathogens of forest and ornamental trees. Some of them form large long‑living clones that are considered as one of the largest organisms on earth and are capable of long‑range spore‑mediated transfer as well as vegetative spread by drought‑resistant hyphal cords called rhizomorphs. However, the virus community infecting these species has remained unknown. In this study we used dsRNA screening and high‑throughput sequencing to search for possible virus infections in a collection of Armillaria isolates representing three diferent species: Armillaria mellea from South Africa, A. borealis from Finland and Russia (Siberia) and A. cepistipes from Finland. Our analysis revealed the presence of both negative‑ sense RNA viruses and positive‑sense RNA viruses, while no dsRNA viruses were detected. The viruses included putative new members of virus families Mymonaviridae, Botourmiaviridae and Virgaviridae and members of a recently discovered virus group tentatively named “ambiviruses” with ambisense bicistronic genomic organization. We demonstrated that Armillaria isolates can be cured of viruses by thermal treatment, which enables the examination of virus efects on host growth and phenotype using isogenic virus‑infected and virus‑free strains. Te fungal genus Armillaria (Fr.) Staude includes more than 40 described species1. Tey are mainly known as notorious plant pathogens of managed natural forests and plantations of non-native tree species that infect hundreds of diferent plants, including economically important conifers (e.g.

  • Direct Analysis of Wood-Inhabiting Fungi Using Denaturing Gradient Gel Electrophoresis of Amplified Ribosomal DNA
    Mycol. Res. 104 (8): 927–936 (August 2000). Printed in the United Kingdom. 927 Direct analysis of wood-inhabiting fungi using denaturing gradient gel electrophoresis of amplified ribosomal DNA Eeva J. VAINIO* and Jarkko HANTULA Finnish Forest Research Institute, P.O. Box 18, FIN-01301, Vantaa, Finland. E-mail: eeva.vainio!metla.fi. Received 13 August 1999; accepted 20 November 1999. Four different primer pairs were designed for the preferential PCR amplification of fungal SSU rDNA directly from environmental samples. Most of the amplification products obtained from a reference collection of 46 wood-decomposing fungi could be separated by denaturing gradient gel electrophoresis (DGGE) using 1650 bp rDNA fragments produced by primer pair FR1jNS1. A relatively high level of resolution was also achieved using 390 bp products amplified with primer pair FR1jFF390. In contrast, the separation of amplification products obtained by the remaining two primer pairs (FR1jFF700 and FR1jFF1100; 700 bp and 1100 bp, respectively) was inadequate when applied to our fungal collection. Differentiation between all the species tested was achieved by combined analysis of the rDNA fragments produced by primer pairs FR1jNS1 and FR1jFF390. The DGGE analysis of environmental samples collected from Norway spruce stumps showed that the analysis of fungal DNA extracted directly from wood was usually in accordance with the investigation of mycelial cultures isolated from the same decay column. In some cases, however, disagreement was observed, which suggests that these two fundamentally different techniques present different views about fungal diversity. The investigation of fungal species profiles directly from environmental samples using DGGE analysis of PCR-amplified SSU rDNA molecules can be used to improve the detection of fungal groups that are difficult to cultivate.
