Anamorphic Fungi: Hyphomycetes
Cryptogamie, Mycologie, 2009, 30 (2): 199-222 © 2009 Adac. Tous droits réservés Novel fungal taxa from the arid Middle East introduced prior to the year 1940. II - Anamorphic Fungi: Hyphomycetes JeanMOUCHACCA Département de Systématique & Evolution (Laboratoire de Cryptogamie), USM 602 Taxonomie & Collections, Muséum National d’Histoire Naturelle, Case Postale 39, 57 rue Cuvier, 75231 Paris Cedex 05, France [email protected] Abstract – The second contribution of this series surveys 44 hyphomycetes having holotypes from the Middle East region and original protologues elaborated before 1940. The oldest binomial disclosed is Torula hammonis ; it was written by Ehrenberg in 1824 on the voucher specimen of a fungus he collected in Egypt. From 1824-1900 simply 8 new taxa were named. None was established in the first decade of the 20th century, while a large proportion was issued in the years 1910-1930: 68.2%. Most novelties were described as species, and fewer were considered varieties or forma of known species; the genus Lacellina was proposed for L. libyca, now L . graminicola . The relevant protologues were elaborated by few mycologists active in France, Germany and Italy. The new organisms commonly developed on parts of green plants collected by European residents or travellers botanists. The original localities of collections are now situated in Egypt, Irak, Libya, Palestine and Yemen. Over half of the novel taxa originates from Egypt. Such includes the oldest 6 species due to Ehrenberg and Thuemen (1876-1880), and another 16 taxa due to Reichert in 1921; the specimens of the latter were collected by Schweinfurth and Ehrenberg with occasional ones by Th. -
1 Etiology, Epidemiology and Management of Fruit Rot Of
Etiology, Epidemiology and Management of Fruit Rot of Deciduous Holly in U.S. Nursery Production Dissertation Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Shan Lin Graduate Program in Plant Pathology The Ohio State University 2018 Dissertation Committee Dr. Francesca Peduto Hand, Advisor Dr. Anne E. Dorrance Dr. Laurence V. Madden Dr. Sally A. Miller 1 Copyrighted by Shan Lin 2018 2 Abstract Cut branches of deciduous holly (Ilex spp.) carrying shiny and colorful fruit are popularly used for holiday decorations in the United States. Since 2012, an emerging disease causing the fruit to rot was observed across Midwestern and Eastern U.S. nurseries. A variety of other symptoms were associated with the disease, including undersized, shriveled, and dull fruit, as well as leaf spots and early plant defoliation. The disease causal agents were identified by laboratory processing of symptomatic fruit collected from nine locations across four states over five years by means of morphological characterization, multi-locus phylogenetic analyses and pathogenicity assays. Alternaria alternata and a newly described species, Diaporthe ilicicola sp. nov., were identified as the primary pathogens associated with the disease, and A. arborescens, Colletotrichum fioriniae, C. nymphaeae, Epicoccum nigrum and species in the D. eres species complex were identified as minor pathogens in this disease complex. To determine the sources of pathogen inoculum in holly fields, and the growth stages of host susceptibility to fungal infections, we monitored the presence of these pathogens in different plant tissues (i.e., dormant twigs, mummified fruit, leaves and fruit), and we studied inoculum dynamics and assessed disease progression throughout the growing season in three Ohio nurseries exposed to natural inoculum over two consecutive years. -

Cheatgrass stand failures have been observed throughout the invaded region, the cause of which may be related to the presence of several species of pathogenic fungi in the soil or surface litter. In this study, metagenomics was used to better understand and compare the fungal communities between sites that have and have not experienced stand failure. -

Gareth Jones, [email protected] Abstract: Phylogenetic analyses of four nuclear genes, namely the large and small subunits of the nuclear ribosomal RNA, transcription elongation factor 1-alpha and the second largest RNA polymerase II subunit, established that the ecological group of marine bitunicate ascomycetes has representatives in the orders Capnodiales, Hysteriales, Jahnulales, Mytilinidiales, Patellariales and Pleosporales. Most of the fungi sequenced were intertidal mangrove taxa and belong to members of 12 families in the Pleosporales: Aigialaceae, Didymellaceae, Leptosphaeriaceae, Lenthitheciaceae, Lophiostomataceae, Massarinaceae, Montagnulaceae, Morosphaeriaceae, Phaeosphaeriaceae, Pleosporaceae, Testudinaceae and Trematosphaeriaceae. Two new families are described: Aigialaceae and Morosphaeriaceae, and three new genera proposed: Halomassarina, Morosphaeria and Rimora. -

This workshop was co-organized with the COST Action FA1303 entitled “Sustainable control of grape- vine trunk diseases” and supported by the International Organization of Vine and Wine (OIV). The meeting was attended by 240 participants from 29 countries and 155 papers were presented either as oral (63) or poster (92) presentations in four sessions: Pathogen characterization, Detection and epidemiology, Micro- bial ecology, Host-pathogen and fungus-fungus competitive interactions and Disease management. A field tour in the champagne vineyard was co-organized by the Comité Interprofessionnel du Vin de Champagne (CIVC). Delegates were presented with an overview of the Champagne region focussing on “terroir”, varietal crea- tion and grapevine diseases, especially GTDs. The tour concluded with a visit to Mercier cellar with cham- pagne tasting. The workshop is the 10th organized by the International Council on Grapevine Trunk Diseases (www. icgtd.org) and the 2nd one organised by the members of the COST Action FA1303 (www.managtd.eu).

<I>Cymadothea Trifolii</I>
Persoonia 22, 2009: 49–55 www.persoonia.org RESEARCH ARTICLE doi:10.3767/003158509X425350 Cymadothea trifolii, an obligate biotrophic leaf parasite of Trifolium, belongs to Mycosphaerellaceae as shown by nuclear ribosomal DNA analyses U.K. Simon1, J.Z. Groenewald2, P.W. Crous2 Key words Abstract The ascomycete Cymadothea trifolii, a member of the Dothideomycetes, is unique among obligate bio- trophic fungi in its capability to only partially degrade the host cell wall and in forming an astonishingly intricate biotrophy interaction apparatus (IA) in its own hyphae, while the attacked host plant cell is triggered to produce a membranous Capnodiales bubble opposite the IA. However, no sequence data are currently available for this species. Based on molecular Cymadothea trifolii phylogenetic results obtained from complete SSU and partial LSU data, we show that the genus Cymadothea be- Dothideomycetes longs to the Mycosphaerellaceae (Capnodiales, Dothideomycetes). This is the first report of sequences obtained GenomiPhi for an obligate biotrophic member of Mycosphaerellaceae.

Bluhm, Ph.D. Thesis Director _________________________________ John Rupe, Ph.D. Committee Member __________________________________ Ainong Shi, Ph.D. Committee Member Abstract Frogeye leaf spot (FLS), caused by Cercospora sojina, is an important and recurrent disease of soybean in many production regions. Genetic resistance is potentially one of the most cost-effective and sustainable strategies to control FLS. However, C. sojina has already demonstrated the ability to overcome resistance conveyed by single R-genes (resistance genes) of soybeans, followed by the emergence of new physiological races. -
