  • A Polyphasic Approach to Characterise Phoma and Related Pleosporalean Genera

Aveskamp, [email protected] #Current address: Mycolim BV, Veld Oostenrijk 13, 5961 NV Horst, The Netherlands Abstract: Fungal taxonomists routinely encounter problems when dealing with asexual fungal species due to poly- and paraphyletic generic phylogenies, and unclear species boundaries. These problems are aptly illustrated in the genus Phoma. This phytopathologically significant fungal genus is currently subdivided into nine sections which are mainly based on a single or just a few morphological characters. However, this subdivision is ambiguous as several of the section-specific characters can occur within a single species. In addition, many teleomorph genera have been linked to Phoma, three of which are recognised here. In this study it is attempted to delineate generic boundaries, and to come to a generic circumscription which is more correct from an evolutionary point of view by means of multilocus sequence typing. Therefore, multiple analyses were conducted utilising sequences obtained from 28S nrDNA (Large Subunit - LSU), 18S nrDNA (Small Subunit - SSU), the Internal Transcribed Spacer regions 1 & 2 and 5.8S nrDNA (ITS), and part of the β-tubulin (TUB) gene region.

Recent molecular, phylogenetic studies led to the conclusion that Phoma should be restricted to Didymellaceae. The present study focuses on the taxonomy of excluded Phoma species, currently classified inPhoma sections Plenodomus, Heterospora and Pilosa. Species of Leptosphaeria and Phoma section Plenodomus are reclassified in Plenodomus, Subplenodomus gen. nov., Leptosphaeria and Paraleptosphaeria gen. nov., based on the phylogeny determined by analysis of sequence data of the large subunit 28S nrDNA (LSU) and Internal Transcribed Spacer regions 1 & 2 and 5.8S nrDNA (ITS). Phoma heteromorphospora, type species of Phoma section Heterospora, and its allied species Phoma dimorphospora, are transferred to the genus Heterospora stat. nov. The Phoma acuta complex (teleomorph Leptosphaeria doliolum), is revised based on a multilocus sequence analysis of the LSU, ITS, small subunit 18S nrDNA (SSU), β-tubulin (TUB), and chitin synthase 1 (CHS-1) regions.

Four data sets were analysed: a) the internal transcribed spacer region including ITS1, 5.8S rDNA and ITS2 (ITS), b) nc28S (ncLSU) rDNA, c) nc18S (ncSSU) rDNA, and d) a combined data set of ncLSU-ncSSU-RPB2 (ribosomal polymerase B2). The traditional placement of Ch. tulasneorum in the Microascales based on ncLSU sequences is unsupported and Australiasca does not belong to the Chaetosphaeriaceae. Both holomorph species are nested within the Glomerellales. A new genus, Reticulascus, is introduced for Ch. tulasneorum with associated Cylindrotrichum anamorph; another species of Reticulascus and its anamorph in Cylindrotrichum are described as new. The taxonomic structure of the Glomerellales is clarified and the name is validly published. As delimited here, it includes three families, the Glomerellaceae and the newly described Australiascaceae and Reticulascaceae. Based on ITS and ncLSU rDNA sequence analyses, we confirm the synonymy of the anamorph generaDischloridium with Monilochaetes.

Based on morphology and DNA sequence data Dothideomycetes of the large subunit nuclear ribosomal RNA gene (LSU, 28S) and the internal transcribed spacers (ITS) and Eudarluca 5.8S rRNA gene of the nrDNA operon, the genus Sphaerellopsis is shown to belong to Leptosphaeriaceae in Fungiculous fungi Dothideomycetes. Sphaerellopsis is circumscribed, and the sexually typified generic name Eudarluca treated as ITS a synonym on the basis that Sphaerellopsis is more commonly used in literature, is the older generic name, and LSU is the morph commonly encountered by plant pathologists in the field.

  • 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.
