Crous CBS-KNAW Fungal Biodiversity Centre, Uppsalalaan 8, 3584 CT Utrecht, The Netherlands CBS-KNAW Fungal Biodiversity Centre, Utrecht, The Netherlands An institute of the Royal Netherlands Academy of Arts and Sciences DEDICATION This volume is dedicated to Brian C. Sutton, fungal systematist non plus ultra and Chief Mycologist at the International Mycological Institute (IMI) until his retirement in 1995. After arrival at IMI straight from university in 1959, Brian was faced with the choice of specialising in rusts or coelomycetes (fungi forming conidia within fruit-bodies). His courageous decision to work with the then almost unknown coelomycete group paved the way for a long and diverse career. Many of the fungi he worked with are minute and require patient and meticulous analytical microscopy. Brian’s ability to see almost invisible details of conidiomatal anatomy, conidiogenesis and conidium morphology, and to translate these observations into detailed descriptions and beautiful line drawings, made him one of the most celebrated fungal systematists of the pre-molecular era. He has a voluminous publication record, and his 1980 monograph “The Coelomycetes – Fungi imperfecti with pycnidia, acervuli and stromata” is still the basic standard morphological reference work for this group of fungi. The diversity of his output can be judged by the list of 990 fungal names he authored or co-authored. Some of these were imaginatively named, including the genera Satchmopsis (in honour of his jazz hero Louis Armstrong) and Omega (the final taxon published inTransactions of the British Mycological Society, of which he was Senior Editor between 1977 and 1988). Brian was always generous with his time in support of fellow mycologists and students from all over the globe, who sent him numerous collections of “troublesome” coelomycetes. On many occasions, these initial requests for help led on to mentoring of the developing scientific careers of his correspondents, and to continuing collaborations in fungal systematics. Brian’s involvement with Colletotrichum began with a paper on C. dematium and C. trichellum in 1962, and developed as the subject for his PhD thesis which focused on the morphology and ontogeny of species associated with grasses. His were the first scientific contributions that established the importance of appressorium morphology in Colletotrichum systematics. After studies of conidial fungi in almost all the branches and bywaters of the Ascomycota, his second major contribution was to provide a user-friendly guide to Colletotrichum in the 1980 Coelomycetes monograph, which built on von Arx’s work to provide a framework for morphology-based identification that still has value today. This was followed by a further systematic account in 1992, which increased the number of accepted species to 39. Brian retired shortly before the fungal molecular phylogenetic revolution gained pace. Although the classification he developed inThe Coelomycetes was unavoidably artificial, it continues to play a major role in ground-truthing of the results of new phylogenetic research, Brian Sutton working in his office (1992), in the final days of the International through integration with recent studies that add molecular data to Mycological Institute at Kew (photo by David Minter). Brian’s original morphological observations. Other than his love for fungi, Brian’s love for jazz music is well known among his mycological colleagues. Our decision to dedicate this volume to him comes with the expectation that he will be paging through it with something soothing playing in the background. Although the backbone of Colletotrichum systematics remains unaltered more than thirty years after The Coelomycetes was published, we hope that recognition of the cryptic lineages within the species complexes included in this volume goes some way towards explanation of their extraordinary variation. “And it feels like rain “ing species” – Buddy Guy The Editors September 2012 CONTENTS U.

    Importation of Fresh Beans (Phaseolus vulgaris L.), Shelled or in Pods, from Jordan into the Continental United States A Qualitative, Pathway-Initiated Risk Assessment February 14, 2011 Version 2 Agency Contact: Plant Epidemiology and Risk Analysis Laboratory Center for Plant Health Science and Technology United States Department of Agriculture Animal and Plant Health Inspection Service Plant Protection and Quarantine 1730 Varsity Drive, Suite 300 Raleigh, NC 27606 Pest Risk Assessment for Beans from Jordan Executive Summary In this risk assessment we examined the risks associated with the importation of fresh beans (Phaseolus vulgaris L.), in pods (French, green, snap, and string beans) or shelled, from the Kingdom of Jordan into the continental United States. We developed a list of pests associated with beans (in any country) that occur in Jordan on any host based on scientific literature, previous commodity risk assessments, records of intercepted pests at ports-of-entry, and information from experts on bean production. This is a qualitative risk assessment, as we express estimates of risk in descriptive terms (High, Medium, and Low) rather than numerically in probabilities or frequencies. We identified seven quarantine pests likely to follow the pathway of introduction. We estimated Consequences of Introduction by assessing five elements that reflect the biology and ecology of the pests: climate-host interaction, host range, dispersal potential, economic impact, and environmental impact. We estimated Likelihood of Introduction values by considering both the quantity of the commodity imported annually and the potential for pest introduction and establishment. We summed the Consequences of Introduction and Likelihood of Introduction values to estimate overall Pest Risk Potentials, which describe risk in the absence of mitigation.

Fungal endophyte studies have increased rapidly over the past decade, using traditional culturing or by utilizing Next Generation Sequencing (NGS) to recover fastidious or rare taxa. Despite increasing interest in fungal endophytes, there is still an enormous amount of ecological diversity that remains poorly understood. In this dissertation, I explore the fungal endophyte biodiversity associated within two plant hosts (Cornus L. species) and (Panicum virgatum L.), create a NGS pipeline, facilitating comparison between traditional culturing method and culture- independent metagenomic method. The diversity and functions of fungal endophytes inhabiting leaves of woody plants in the temperate region are not well understood. I explored the fungal biodiversity in native Cornus species of North American and Japan using traditional culturing ii techniques. Samples were collected from regions with similar climate and comparison of fungi was done using two years of collection data.

Host-specific mortality from natural enemies is one of the most widely tested hypotheses in community ecology to explain the high biodiversity of forests. The effects of fungal pathogens on seedling survival are usually discussed under the framework of the Janzen-Connell (JC) hypothesis, which posits that seedlings are more likely to survive when dispersed far from the parent tree or at low densities due to pressure from host-specific pathogens (Janzen 1970, Connell 1971).

(2009). Colletotrichum: a catalogue of confusion. Fungal Diversity 39: 1-17. Identification of Colletotrichum species has long been difficult due to limited morphological characters. Single gene phylogenetic analyses have also not proved to be very successful in delineating species. This may be partly due to the high level of erroneous names in GenBank. In this paper we review the problems associated with taxonomy of Colletotrichum and difficulties in identifying taxa to species. We advocate epitypification and use of multi-locus phylogeny to delimit species and gain a better understanding of the genus. We review the lifestyles of Colletotrichum species, which may occur as epiphytes, endophytes, saprobes and pathogens.

  • Colletotrichum Acutatum
    Prepared by CABI and EPPO for the EU under Contract 90/399003 Data Sheets on Quarantine Pests Colletotrichum acutatum IDENTITY Name: Colletotrichum acutatum Simmonds Synonyms: Colletotrichum xanthii Halsted Taxonomic position: Fungi: Ascomycetes: Polystigmatales (probable anamorph) Common names: Anthracnose, black spot (of strawberry), terminal crook disease (of pine), leaf curl (of anemone and celery), crown rot (especially of anemone and celery) (English) Taches noires du fraisier (French) Manchas negras del fresón (Spanish) Notes on taxonomy and nomenclature: The classification of the genus Colletotrichum is currently very unsatisfactory, and several species occur on the principal economic host (strawberry) which are regularly confused. As well as C. acutatum, these include the Glomerella cingulata anamorphs C. fragariae and C. gloeosporioides, all of which can be distinguished by isozyme analysis (Bonde et al., 1991). Studies are continuing. Colletotrichum xanthii appears to be an earlier name for C. acutatum, but more research is necessary before it is adopted in plant pathology circles. Bayer computer code: COLLAC EU Annex designation: II/A2 HOSTS The species has a very wide host range, but is economically most important on strawberries (Fragaria ananassa). Other cultivated hosts include Anemone coronaria, apples (Malus pumila), aubergines (Solanum melongena), avocados (Persea americana), Camellia spp., Capsicum annuum, Ceanothus spp., celery (Apium graveolens), coffee (Coffea arabica), guavas (Psidium guajava), olives (Olea europea), pawpaws (Carica papaya), Pinus (especially P. radiata and P. elliottii), tamarillos (Cyphomandra betacea), tomatoes (Lycopersicon esculentum), Tsuga heterophylla and Zinnia spp. Colletotrichum acutatum can apparently affect almost any flowering plant, especially in warm temperate or tropical regions, although its host range needs further clarification.
