IAL President Since the inaugural IAL meeting in Münster in March 1986, our society has had tremendously successful and enjoyable meetings. I still remember the first meeting when, for the first time, I met a number of prestigious colleagues and – as an The 8 undergraduate student – could interact with colleagues in a relaxed atmosphere. These meetings are especially vital for th students and early career scientists where they can interact – Lichens in Deep Time IAL Symposium with colleagues and build networks. Older scientists, like myself, can pass on essential guidance to younger scholars, while at the same time also learn from their new and bright ideas. We are confident that this 8th Symposium in Helsinki will be equally as memorable as the previous ones. Helsinki has a rich history and tradition in lichenological research and we are looking forward to this event, entitled ”Lichens in Deep Time”. Contributions to the symposium will reflect the latest trends in using genomic data to better understand the lichen symbiosis and the evolutionary history of its partners, have a strong part in ecological studies, address the threats imposed by rapid man-made changes occurring to the biosphere and an ever-growing interest in tropical lichens. The topics discussed at the symposium will be as diverse as the field of lichenology itself is today. In addition to the scientific presentations and discussion, there is an opulent and exciting social program. Numerous excursions have been organized which I am confident will produce new friendships and collaborations. The scientific committee is optimistic that you will not only enjoy excellent science, but also engage in stimulating interaction with colleagues and a sense of community in one of the major capitals of lichenology. IAL8 • HELSINKI 2016 3 Welcome Message from the Local Organising Committee Dear Colleagues, It gives me great pleasure to welcome you on behalf of the local organising committee to IAL8. We are very excited to be hosting this important conference in Helsinki. We hope to follow in the successful footsteps of the previous IAL Marko Hyvärinen, symposia and make this event as enjoyable as the previous Chairman of the Local ones. Organising Committee Four and a half years ago, right after the inspiring 7th IAL Symposium in Bangkok, we started planning the content of The 8 its successor. During our first brainstorming sessions it was decided that the motto of the congress should be ”Lichens in th Deep Time”, referring to different timescales in evolution, – Lichens in Deep Time IAL Symposium ecology, and environmental change as well as in the history of lichenology. Our wide selection of sessions reflects this idea of exploring changes in lichens at different timescales and also changes in the way we perceive the very concept of a lichen. To our satisfaction this setting of sessions was well received by the lichenological community, and we now have more than 350 presentations to follow and enjoy during the congress week. The previous IAL symposia have proven to have a significant impact on the scientific activity in the field of lichenology in hosting countries. Invigorating our long tradition in lichen research is one of the major incentives for us to host the congress. However, together with the science we also want to celebrate public outreach. The ways to communicate the value of science and present the beauty of lichen diversity are variable and some of these ways are presented during the social programme of the week as well as in the pre- and post- congress excursions organised by our collaborators in the universities of Turku and Oulu. We in the Finnish Museum of Natural History ’Luomus’ are especially proud to announce the publication of the brand new book, ”Lichens of Finland” that is based on the award-winning Finnish books ”Suomen jäkäläopas” and ”Suomen rupijäkälät”. We welcome you all, and particularly those of you, who have had to travel far to join us; we wish you all a pleasant and fruitful stay. Tervetuloa jäkälöitymään! (Welcome to get lichenized) IAL8 • HELSINKI 2016 5 Opening Address CEO, Finnish Museum of Natural History ’Luomus’ Dear Lichenologists, On behalf of the Finnish Museum of Natural history ’Luomus’ and the University of Helsinki, I am very pleased and happy to welcome all 300 delegates from 46 countries who have Leif Schulman, honoured us by taking part in IAL8 in Helsinki. Director of the Finnish Museum of Natural Lichens in Deep Time is a most suitable topic for a congress History ’Luomus’ at the University of Helsinki, which has a deep tradition in lichenology. This history is reflected in the exceptionally The 8 rich lichen collections that we at Luomus are proud to keep for current and future generations of researchers. They are a th part of Finland’s national natural history collections, the care – Lichens in Deep Time IAL Symposium of which is the core duty of Luomus. In addition, Luomus is constituted to conduct research on the collections and display them to the public. These duties are intertwined in a fruitful interaction – indeed like the symbionts of a lichenized fungus – and I hope you will have some time to familiarise yourselves with and benefit from all these resources of Luomus. I wish to express my warmest thanks to the IAL Council led by the President of the IAL, Thorsten Lumbsch and to the Local Organising Committee led by Marko Hyvärinen for their joint venture to build a platform for fascinating and informative scientific presentations. The scientific programme of the conference looks impressive and seems to address questions that have wide relevance far beyond the borders of lichenology. I hope that the exciting social programme will entail plenty of opportunities for stimulating conversations and relaxation. I wish you a productive symposium and fruitful discussions, and hope that IAL8 will have a major impact on the international community of lichenologists.

Mycosphere 10(1), 310–489, Doi 10.5943/mycosphere/10/1/7 Abstract Leotiomycetes is regarded as the inoperculate class of discomycetes within the phylum Ascomycota. Taxa are mainly characterized by asci with a simple pore blueing in Melzer’s reagent, although some taxa have lost this character. The monophyly of this class has been verified in several recent molecular studies. However, circumscription of the orders, families and generic level delimitation are still unsettled. This paper provides a modified backbone tree for the class Leotiomycetes based on phylogenetic analysis of combined ITS, LSU, SSU, TEF, and RPB2 loci. In the phylogenetic analysis, Leotiomycetes separates into 19 clades, which can be recognized as orders and order-level clades.

Abstract: The 11th fascicle (20 numbers) of the exsiccata 'Licheni- colous Biota' is published. The issue contains material of 20 non- lichenized fungal taxa (16 teleomorphs of ascomycetes, 2 anamorphic states of ascomycetes, 2 basidiomycetes), including paratype material of Tremella graphidis Diederich et al. (no 269). Furthermore, collections of the type species of the following genera are distributed: Abrothallus (A. bertianus), Lichenostigma (L. maureri), Phacopsis (P. vulpina), Skyt- tea (S. nitschkei), and Telogalla (T. olivieri). *Institut für Pflanzenwissenschaften, NAWI Graz, Karl-Franzens-Universität, Holteigasse 6, A-8010 Graz, AUSTRIA. e-mail: [email protected] Introduction The exsiccata 'Lichenicolous Biota' is continued with fascicle 11 containing 20 numbers. The exsiccata covers all lichenicolous biota, i.e., it is open not only to non- lichenized and lichenized fungi, but also to myxomycetes, bacteria, and even ani- mals, whenever they cause a characteristic symptom on their host (e.g., discoloration or galls). Consequently, the exsiccata contains both highly host-specific and pluri- vorous species, as long as the individuals clearly grow upon a lichen and the col- lection is homogeneous, so that identical duplicates can be prepared. The five complete sets are sent to herbaria of the following regions: Central Europe (Graz [GZU]), Northern Europe (Uppsala [UPS]), Western Europe (Bruxelles [BR]), North America (New York [NY]), Australasia (Canberra [CANB]).

Ballhorn, Chair Mitchell B. Cruzan Todd N. Rosenstiel John G. Bishop Catherine E. de Rivera Portland State University 2018 © 2018 Brett Steven Younginger Abstract Fungal endophytes are highly diverse, cryptic plant endosymbionts that form asymptomatic infections within host tissue. They represent a large fraction of the millions of undescribed fungal taxa on our planet with some demonstrating mutualistic benefits to their hosts including herbivore and pathogen defense and abiotic stress tolerance. Other endophytes are latent saprotrophs or pathogens, awaiting host plant senescence to begin alternative stages of their life cycles.

The new genus is similar to Skyttea and Diplolaeviopsis from which it clearly differs in larger apothecia with widely exposed black pigmented discs, macroscopically easily visible long excipular hairs covering the whole exciple, and different ascus structure. Our results based on Maximum Likelihood (ML) and Bayesian analysis of three loci (nuSSU, nuLSU and 5.8S of the ITS) suggest that the new genus belong to Helotiales and is sister to Diplolaeviopsis ranula within encoelioid-clade. The conidial-ascosporic connection of Diplolaeviopsis ranula is shown here based on the nucleotide match of rDNA sequences.

Catcheside1 Received: 3 March 2019 /Revised: 1 May 2019 /Accepted: 7 May 2019 # German Mycological Society and Springer-Verlag GmbH Germany, part of Springer Nature 2019 Abstract A new genus of helotialean fungi, Annabella gen. nov. (Cordieritidaceae), is described to accommodate Annabella australiensis sp. nov. This species was collected on attached decaying wood of Avicennia marina, a common mangrove species found in protected waters of southern Australia. Annabella is distinctive among Cordieritidaceae in having relatively small perithecioid hyaline to yellowish apothecia and by the absence of an ionomidotic reaction. The apothecial shape and size of Annabella is most similar to Skyttea. The molecular phylogenetic analysis of a concatenated dataset of three ribosomal nuclear loci confirms the placement of Annabella within Cordieritidaceae, as a sister clade to Skyttea.

This study focuses on lichenicolous fungi inhabiting the genus Lobariella Accepted: 16 Nov. 2019 (Peltigerales), one of the most important lichen hosts in the Andean cloud forests. Based Published: 2 Dec. 2019 on molecular and morphological data, three new genera are introduced: Lawreyella gen. Associate Editor nov. (Cordieritidaceae, for Unguiculariopsis lobariella), Neobaryopsis gen. nov. (Cordy- Paul Diederich cipitaceae), and Pseudodidymocyrtis gen. nov. (Didymosphaeriaceae). Nine additional new species are described (Abrothallus subhalei sp. nov., Atronectria lobariellae sp. nov., Corticifraga microspora sp. nov., Epithamnolia rugosopycnidiata sp. nov., Lichenotubeufia cryptica sp. nov., Neobaryopsis andensis sp. nov., Pseudodidymocyrtis lobariellae sp. nov., Rhagadostomella hypolobariella sp. nov., and Xylaria lichenicola sp. nov.). Phylogenetic placements of 13 lichenicolous species are reported here for Abrothallus, Arthonia, Glo- bonectria, Lawreyella, Monodictys, Neobaryopsis, Pseudodidymocyrtis, Sclerococcum, Trichonectria and Xylaria. The name Sclerococcum ricasoliae comb. nov. is reestablished for the neotropical populations formerly named S.

  • An Inventory of Fungal Diversity in Ohio Research Thesis Presented In
    An Inventory of Fungal Diversity in Ohio Research Thesis Presented in partial fulfillment of the requirements for graduation with research distinction in the undergraduate colleges of The Ohio State University by Django Grootmyers The Ohio State University April 2021 1 ABSTRACT Fungi are a large and diverse group of eukaryotic organisms that play important roles in nutrient cycling in ecosystems worldwide. Fungi are poorly documented compared to plants in Ohio despite 197 years of collecting activity, and an attempt to compile all the species of fungi known from Ohio has not been completed since 1894. This paper compiles the species of fungi currently known from Ohio based on vouchered fungal collections available in digitized form at the Mycology Collections Portal (MyCoPortal) and other online collections databases and new collections by the author. All groups of fungi are treated, including lichens and microfungi. 69,795 total records of Ohio fungi were processed, resulting in a list of 4,865 total species-level taxa. 250 of these taxa are newly reported from Ohio in this work. 229 of the taxa known from Ohio are species that were originally described from Ohio. A number of potentially novel fungal species were discovered over the course of this study and will be described in future publications. The insights gained from this work will be useful in facilitating future research on Ohio fungi, developing more comprehensive and modern guides to Ohio fungi, and beginning to investigate the possibility of fungal conservation in Ohio. INTRODUCTION Fungi are a large and very diverse group of organisms that play a variety of vital roles in natural and agricultural ecosystems: as decomposers (Lindahl, Taylor and Finlay 2002), mycorrhizal partners of plant species (Van Der Heijden et al.
