Phylogeny and Classification of Cryptodiscus, with a Taxonomic Synopsis of the Swedish Species

Box 50007, SE-104 05 Stockholm, Sweden. 2Department of Ecology and Environmental Sciences, Umeå University, SE-901 87 Umeå, Sweden. 3Jodrell Laboratory, Royal Botanic Gardens, Kew, Richmond, Surrey, TW9 3AB, UK. Baloch, E., Gilenstam, G. and Wedin, M. (2009). Phylogeny and classification of Cryptodiscus, with a taxonomic synopsis of the Swedish species. Fungal Diversity 38: 51-68. The phylogeny, taxonomy and classification of Cryptodiscus are examined. The current generic and species delimitations, and the relationship of the genus within the Ostropomycetidae, are tested by molecular phylogenetic analyses of the nuclear ITS and LSU rDNA and the mitochondrial SSU rDNA. In our new circumscription Cryptodiscus is a monophyletic group of saprotrophic and lichenized fungi characterized by small, urceolate apothecia, mostly hyaline ascomatal walls without any embedded crystals, no clear periphysoids, and with oblong to narrow- cylindrical septate ascospores. Cryptodiscus forms a well-supported clade together with Absconditella and the remaining Stictidaceae. Paschelkiella and Bryophagus are synonymised with Cryptodiscus. Species excluded from Cryptodiscus are Cryptodiscus anguillosporus, C. angulosus, C. microstomus, and C. rhopaloides. Cryptodiscus in Sweden is revised and six species are accepted, of which one is newly described: C. foveolaris, C. gloeocapsa comb. nov. (≡ Bryophagus gloeocapsa), C. incolor sp. nov., C. pallidus, C. pini comb. nov. (≡ Paschelkiella pini), and the rediscovered species C. tabularum.

NETWORKING FOR DIVERSITY Annual Report 2017 – 2019 2017 – BGBM BGBM Annual Report 2017 – 2019 Cover image: Research into global biodiversity and its significance for humanity is impossible without networks. The topic of networking can be understood in different ways: in the natural world, with the life processes within an organism – visible in the network of the veins of a leaf or in the genetic diversity in populations of plants – networking takes place by means of pollen, via pollinators or the wind. In the world of research, individual objects, such as a particular plant, are networked with the data obtained from them. Networking is also crucial if this data is to be effective as a knowledge base for solving global issues of the future: collaboration between scientific experts within and across disciplines and with stakeholders at regional, national and international level.

M. van Leeuwen2, C. André Lévesque4 and Theo A. J. van der Lee1 Abstract Background: Chytridiomycota species (chytrids) belong to a basal lineage in the fungal kingdom. Inhabiting terrestrial and aquatic environments, most are free-living saprophytes but several species cause important diseases: e.g. Batrachochytrium dendrobatidis, responsible for worldwide amphibian decline; and Synchytrium endobioticum, causing potato wart disease. S. endobioticum has an obligate biotrophic lifestyle and isolates can be further characterized as pathotypes based on their virulence on a differential set of potato cultivars. Quarantine measures have been implemented globally to control the disease and prevent its spread. We used a comparative approach using chytrid mitogenomes to determine taxonomical relationships and to gain insights into the evolution and recent history of introductions of this plant pathogen.

Blastomycosis Surveillance in 5 States, United States, 1987–2018
Article DOI: https://doi.org/10.3201/eid2704.204078 Blastomycosis Surveillance in 5 States, United States, 1987–2018 Appendix State-Specific Blastomycosis Case Definitions Arkansas No formal case definition. Louisiana Blastomycosis is a fungal infection caused by Blastomyces dermatitidis. The organism is inhaled and typically causes an acute pulmonary infection. However, cutaneous and disseminated forms can occur, as well as asymptomatic self-limited infections. Clinical description Blastomyces dermatitidis causes a systemic pyogranulomatous disease called blastomycosis. Initial infection is through the lungs and is often subclinical. Hematogenous dissemination may occur, culminating in a disease with diverse manifestations. Infection may be asymptomatic or associated with acute, chronic, or fulminant disease. • Skin lesions can be nodular, verrucous (often mistaken for squamous cell carcinoma), or ulcerative, with minimal inflammation. • Abscesses generally are subcutaneous cold abscesses but may occur in any organ. • Pulmonary disease consists of a chronic pneumonia, including productive cough, hemoptysis, weight loss, and pleuritic chest pain. • Disseminated blastomycosis usually begins with pulmonary infection and can involve the skin, bones, central nervous system, abdominal viscera, and kidneys. Intrauterine or congenital infections occur rarely.

BADALYAN1, MÓNICA NAVARRO-GONZÁLEZ2, URSULA KÜES2 1Laboratory of Fungal Biology and Biotechnology, Faculty of Biology, Yerevan State University 1 Aleg Manoogian St., 0025, Yerevan Armenia 2Georg-August-Universität Göttingen, Büsgen-Institut, Molekulare Holzbiotechnologie und technische Mykologie Büsgenweg 2, 37077 Göttingen Germany [email protected] , [email protected] , [email protected] ABSTRACT Ink cap fungi (coprinoid mushrooms) are not monophyletic and divide into Coprinellus, Coprinopsis and Parasola (all Psathyrellaceae) and Coprinus (Agaricaceae). Knowledge on morphological mycelial features and asexual reproduction modes of coprini is restricted, with Coprinopsis cinerea being the best described species. This species produces constitutively on monokaryons and light-induced on dikaryons unicellular uninucleate haploid arthroconidia (oidia) on specific aerial structures (oidiophores). The anamorphic name Hormographiella aspergillata was coined for oidia production on monokaryons. Two other Hormographiella species are described in the literature, one unknown (candelabrata) and one (verticillata) identified as Coprinellus domesticus. Another, yet sterile anamorph associated with some coprini is called Ozonium which describes the incidence of tawny-rust mycelial mats of pigmented, well septated and clampless hyphal strands as -

ARTICLE https://doi.org/10.1038/s41467-021-25308-w OPEN Phylogenomics of a new fungal phylum reveals multiple waves of reductive evolution across Holomycota ✉ ✉ Luis Javier Galindo 1 , Purificación López-García 1, Guifré Torruella1, Sergey Karpov2,3 & David Moreira 1 Compared to multicellular fungi and unicellular yeasts, unicellular fungi with free-living fla- gellated stages (zoospores) remain poorly known and their phylogenetic position is often 1234567890():,; unresolved. Recently, rRNA gene phylogenetic analyses of two atypical parasitic fungi with amoeboid zoospores and long kinetosomes, the sanchytrids Amoeboradix gromovi and San- chytrium tribonematis, showed that they formed a monophyletic group without close affinity with known fungal clades. Here, we sequence single-cell genomes for both species to assess their phylogenetic position and evolution. Phylogenomic analyses using different protein datasets and a comprehensive taxon sampling result in an almost fully-resolved fungal tree, with Chytridiomycota as sister to all other fungi, and sanchytrids forming a well-supported, fast-evolving clade sister to Blastocladiomycota. Comparative genomic analyses across fungi and their allies (Holomycota) reveal an atypically reduced metabolic repertoire for sanchy- trids. We infer three main independent flagellum losses from the distribution of over 60 flagellum-specific proteins across Holomycota. Based on sanchytrids’ phylogenetic position and unique traits, we propose the designation of a novel phylum, Sanchytriomycota. In addition, our results indicate that most of the hyphal morphogenesis gene repertoire of multicellular fungi had already evolved in early holomycotan lineages. 1 Ecologie Systématique Evolution, CNRS, Université Paris-Saclay, AgroParisTech, Orsay, France. 2 Zoological Institute, Russian Academy of Sciences, St. ✉ Petersburg, Russia. 3 St. -
