Effect of a Trichoderma bio-inoculant on ectomycorrhizal colonisation of Pinus radiata seedlings A thesis submitted in partial fulfilment of the requirements for the Degree of Master of Science at Lincoln University by R.F Minchin Lincoln University 2010 Abstract of a thesis submitted in partial fulfilment of the requirements for the Degree of Master of Science. Abstract Effect of a Trichoderma bio-inoculant on ectomycorrhizal colonisation of Pinus radiata seedlings by R.F Minchin Ectomycorrhizal colonisation potential of Pinus radiata seedlings inoculated with the commercially available Trichoderma species bio-inoculant, Arbor-Guard™, was investigated in a commercial containerised nursery setting and in a separate glasshouse experiment, which included the co-inoculation of specific ectomycorrhizal fungi. Application of Arbor-Guard™ to Pinus radiata seedlings in a containerised commercial nursery had no significant effect on the ability of the naturally occurring ectomycorrhizal (ECM) fungi to colonise the seedlings. Thelephora terrestris was the dominant ectomycorrhizal species colonising the P. radiata root tips and has been described as a species able to rapidly outcompete other ECM species colonisation, particularly in high organic matter media like that used at the containerised commercial nursery investigated. -
A Synopsis of the Saddle Fungi (Helvella: Ascomycota) in Europe – Species Delimitation, Taxonomy and Typification
Persoonia 39, 2017: 201–253 ISSN (Online) 1878-9080 www.ingentaconnect.com/content/nhn/pimj RESEARCH ARTICLE https://doi.org/10.3767/persoonia.2017.39.09 A synopsis of the saddle fungi (Helvella: Ascomycota) in Europe – species delimitation, taxonomy and typification I. Skrede1,*, T. Carlsen1, T. Schumacher1 Key words Abstract Helvella is a widespread, speciose genus of large apothecial ascomycetes (Pezizomycete: Pezizales) that are found in terrestrial biomes of the Northern and Southern Hemispheres. This study represents a beginning on molecular phylogeny assessing species limits and applying correct names for Helvella species based on type material and specimens in the Pezizales university herbaria (fungaria) of Copenhagen (C), Harvard (FH) and Oslo (O). We use morphology and phylogenetic systematics evidence from four loci – heat shock protein 90 (hsp), translation elongation factor alpha (tef), RNA polymerase II (rpb2) and the nuclear large subunit ribosomal DNA (LSU) – to assess species boundaries in an expanded sample of Helvella specimens from Europe. We combine the morphological and phylogenetic information from 55 Helvella species from Europe with a small sample of Helvella species from other regions of the world. Little intraspecific variation was detected within the species using these molecular markers; hsp and rpb2 markers provided useful barcodes for species delimitation in this genus, while LSU provided more variable resolution among the pertinent species. We discuss typification issues and identify molecular characteristics for 55 European Helvella species, designate neo- and epitypes for 30 species, and describe seven Helvella species new to science, i.e., H. alpicola, H. alpina, H. carnosa, H. danica, H. nannfeldtii, H. pubescens and H. -

Phylogeny and Species Delimitation
VOLUME 5 JUNE 2020 Fungal Systematics and Evolution PAGES 169–186 doi.org/10.3114/fuse.2020.05.11 The Helvella corium species aggregate in Nordic countries – phylogeny and species delimitation S.B. Løken, I. Skrede, T. Schumacher Department of Biosciences, University of Oslo, P.O. Box 1066, 0316 Oslo, Norway *Corresponding author: [email protected] Key words: Abstract: Mycologists have always been curious about the elaborate morphotypes and shapes of species of the genus molecular phylogeny Helvella. The small, black, cupulate Helvella specimens have mostly been assigned to Helvella corium, a broadly defined new taxon morpho-species. Recent phylogenetic analyses, however, have revealed an aggregate of species hidden under this Pezizales name. We performed a multispecies coalescent analysis to re-assess species limits and evolutionary relationships of Stacey the Helvella corium species aggregate in the Nordic countries. To achieve this, we used morphology and phylogenetic evidence from five loci – heat shock protein 90 (hsp), translation elongation factor 1-alpha (tef), RNA polymerase II Corresponding editor: (rpb2), and the 5.8S and large subunit (LSU) of the nuclear ribosomal DNA. All specimens under the name Helvella P.W. Crous corium in the larger university fungaria of Norway, Sweden and Denmark were examined and barcoded, using partial hsp and/or rpb2 as the preferential secondary barcodes in Helvella. Additional fresh specimens were collected in three years (2015–2018) to obtain in vivo morphological data to aid in species discrimination. The H. corium species aggregate consists of seven phylogenetically distinct species, nested in three divergent lineages, i.e. H. -
I Funghi Della Zona Subalpina E Alpina Dello Sciliar – Raccolta Dei Dati E Considerazioni Al “Progetto Sciliar”

Results and scientific conclusions include a checklist (578 taxa) with descriptions and illustrations of rare and/or peculiar fungi, as well as ecological considerations based on the recorded fungal community patterns. Keywods: Checklist, Fungi, Basidiomycota, Ascomycota, Myxomycetes, Sciliar, South Tyrol, Italy. 1. Introduzione Quando, nella primavera del 2006, la nostra Associazione micologica fu contattata dall’Ufficio Provinciale “Bacini Montani” e dal Museo di Scienze Naturali di Bolzano per aderire ad un progetto di ricerca sulla biodiversità nella zona dello Sciliar-Schlern, iniziò per noi un'affascinante ed interessante esperienza, che mise alla prova il nostro apparato organizzativo e scientifico. Non era sicuramente la prima esperienza per noi, infatti da molti anni collaboriamo con vari uffici della Provincia Autonoma di Bolzano ad alcuni progetti come il controllo della radioattività ed il monitoraggio ambientale. L’area dello Sciliar-Schlern, non era per noi certo una zona di studio nuova, visto che studiamo intensamente questa zona da oltre 30 anni, assieme a tutta la Provincia di Bolzano, di cui abbiamo intenzione di pubblicare, con il tempo, una completa micoflora. -

Systematics of the Genus Rhizopogon Inferred from Nuclear Ribosomal DNA Large Subunit and Internal Transcribed Spacer Sequences
AN ABSTRACT OF THE THESIS OF Lisa C. Grubisha for the degree of Master of Science in Botany and Plant Pathology presented on June 22, 1998. Title: Systematics of the Genus Rhizopogon Inferred from Nuclear Ribosomal DNA Large Subunit and Internal Transcribed Spacer Sequences. Abstract approved Redacted for Privacy Joseph W. Spatafora Rhizopogon is a hypogeous fungal genus that forms ectomycorrhizae with genera of the Pinaceae. The greatest number and species of Rhizopogon are found in coniferous forests of the Pacific Northwestern United States, where members of the Pinaceae are also concentrated. Rhizopogon spp. are host-specific primarily with Pinus spp. and Pseudotsuga spp. and thus are an important component of these forest ecosystems. Rhizopogon includes over 100 species; however, the systematics of Rhizopogon have not been well understood. Currently the genus is placed in the Boletales, an order of ectomycorrhizal fungi that are primarily epigeous and have a tubular hymenium. Suillus is a stipitate genus closely related to Rhizopogon that is also in the Boletales and host specific with Pinaceae.I examined the relationship of Rhizopogon to Suillus and other genera in the Boletales. Infrageneric relationships in Rhizopogon were also investigated to test current taxonomic hypotheses and species concepts. Through phylogenetic analyses of large subunit and internal transcribed spacer nuclear ribosomal DNA sequences, I found that Rhizopogon and Suillus formed distinct monophyletic groups. Rhizopogon was composed of four distinct groups; sections Amylopogon and Villosuli were strongly supported monophyletic groups. Section Rhizopogon was not monophyletic, and formed two distinct clades. Section Fulviglebae formed a strongly supported group within section Villosuli.
