This study describes the diversity and toxigenic potential of fungal species causing FCR in La Reunion, an island in the Indian Ocean. One-hundred-and-fifty fungal isolates were obtained from infected and healthy fruitlets on Reunion Island and exclusively correspond to two genera of fungi: Fusarium and Talaromyces. -
9B Taxonomy to Genus
Fungus and Lichen Genera in the NEMF Database Taxonomic hierarchy: phyllum > class (-etes) > order (-ales) > family (-ceae) > genus. Total number of genera in the database: 526 Anamorphic fungi (see p. 4), which are disseminated by propagules not formed from cells where meiosis has occurred, are presently not grouped by class, order, etc. Most propagules can be referred to as "conidia," but some are derived from unspecialized vegetative mycelium. A significant number are correlated with fungal states that produce spores derived from cells where meiosis has, or is assumed to have, occurred. These are, where known, members of the ascomycetes or basidiomycetes. However, in many cases, they are still undescribed, unrecognized or poorly known. (Explanation paraphrased from "Dictionary of the Fungi, 9th Edition.") Principal authority for this taxonomy is the Dictionary of the Fungi and its online database, www.indexfungorum.org. For lichens, see Lecanoromycetes on p. 3.

Ovrebo2 1 Department of Biology, Faculty of Natural Sciences, Universidad del Rosario. Bogota, 111221, Colombia. 2 Department of Biology, University of Central Oklahoma. Edmond, OK. USA. ABSTRACT Panamanian montane forests harbor a high diversity of fungi, particularly of ectomycorrhizal (ECM) fungi, however their taxonomy and diversity patterns remain for the most part unexplored. Here we present state of the art fungal taxonomy and diversity patterns at Fortuna Forest Reserve based on morphological and molecular identification of over 1,000 fruiting body collections of macromycetes made over a period of five years. We compare these new results with previously published work based on environmental sampling of Oreomunnea mexicana root tips. We compiled a preliminary list of species and report 22 new genera and 29 new fungal species for Panama. Based on fruiting body collection data we compare the species composition of ECM fungal communities associated with Oreomunnea stands across sites differing in soil fertility and amount of rainfall. We also examine the effect of a long-term nitrogen addition treatment on the fruiting body production of ECM fungi. Finally, we discuss the biogeographic importance of Panama collections which fill in the knowledge gap of ECM fungal records between Costa Rica and Colombia. -

Virtually all Fusarium species synthesize toxic secondary metabolites, known as mycotoxins; however, the roles of mycotoxins are not yet fully understood. To understand how a fungal partner alters its lifestyle to assimilate with the plant host remains a challenge. The review presented the mechanisms of mycotoxin biosynthesis in the Fusarium genus under various environmental conditions, such as pH, temperature, moisture content, and nitrogen source. It also concentrated on plant metabolic pathways and cytogenetic changes that are influenced as a consequence of mycotoxin confrontations. Moreover, we looked through special secondary metabolite production and mycotoxins specific for some significant fungal pathogens-plant host models. Plant strategies of avoiding the Fusarium mycotoxins were also discussed. Finally, we outlined the studies on the potential of plant secondary metabolites in defense reaction to Fusarium infection. Keywords: fungal pathogens; Fusarium; pathogenicity; secondary metabolites Key Contribution: The review summarized the knowledge and recent reports on the involvement of Fusarium mycotoxins in plant infection processes, as well as the consequences for plant metabolism and physiological changes related to the pathogenesis. -

The Importance of Fusarium Fungi in Wheat Cultivation – Pathogenicity and Mycotoxins Production: a Review
Journal of Animal &Plant Sciences, 2014. Vol.21, Issue 2: 3326-3343 Publication date 30/4/2014, http://www.m.elewa.org/JAPS ; ISSN 2071-7024 The Importance of Fusarium Fungi in Wheat Cultivation – Pathogenicity and Mycotoxins Production: A Review Natalia K. Kotowicz, Magdalena Frąc, Jerzy Lipiec Institute of Agrophysics Polish Academy of Sciences, ul. Doświadczalna 4, 20-290 Lublin, Poland E-mail: [email protected] Corresponding author: [email protected] Keywords: Fusarium , wheat diseases, fungicide control, mycotoxins 1. ABSTRACT Globally, cereals occupy about 50% of arable land. In Poland, that share is over 70%. In the structure of cereal crops, wheat is a dominant species. It occupies an area of 2.2 million hectares. The major part of this area is winter wheat, which is responsive to infection by pathogenic fungi. In recent years, the occurrence of pathogenic fungi of the genus Fusarium has been increasing. Their harmful effect consists of deterioration of the quality and quantity of yield and production of mycotoxins that can pose a threat to plants, animals and humans. In order to prevent the development of fusariosis, fungicides are used. However, incompetent and intensive use of fungicides may induce the resistance in strains previously sensitive to those substances. The aim of this essay is to present the problem of pathogenic Fusarium species occurrence in wheat crops and to discuss methods of fungicide control and related problems. 2. INTRODUCTION Wheat has accompanied humans as a bread especially pathogenic fungi that cause leaf, cereal for many decades now. Its cultivation head, and stem diseases (Jaczewska-Kalicka was known as early as the Neolithic Age, about 2010). -
Genera of Corticioid Fungi: Keys, Nomenclature and Taxonomy Article

Studies in Fungi 5(1), 125–309, Doi 10.5943/sif/5/1/12 Abstract A review of the worldwide corticioid homobasidiomycetes genera is presented. A total of 620 genera are considered with comments on their taxonomy and nomenclature. Of them, about 420 are accepted and keyed out, described in detail with remarks on their taxonomy and systematics. Key words – Corticiaceae – Crust fungi – Diversity – Homobasidiomycetes Introduction Corticioid fungi are a diverse and heterogeneous group of fungi mainly referred to basidiomycete fungi in which basidiomes are generally resupinate. Basidiome construction is often simple, and in most cases, only generative hyphae are found. In more structured basidiomes, those with a reflexed margin or with a pileate surface, more or less sclerified hyphae are usually found. Even the basidiome structure is apparently not very complex, hymenophore configuration should be highly variable finding smooth surfaces or different variations to increase the spore production area such as rugose, tuberculate, aculeate, merulioid, folded, or poroid hymenial surfaces. It is often thought that corticioid fungi produce unattractive and little variable forms and, in most cases, they go unnoticed by most mycologists as ungraceful forms that ‘cover sticks and look like a paint stain’. Although the macroscopic variability compared to other fungi is, but not always, usually limited, under the microscope they surprise with a great diversity of forms of basidia, cystidia, spores and other microscopic elements (Hjortstam et al. -

Abstract Endophytes in Maize (Zea mays) in New Zealand by Jennifer Joy Brookes The aim of this study was to isolate fungal endophytes from maize in New Zealand (NZ) and to select endophytes with potential to reduce insect pests and/or plant diseases. Culture methods were used to isolate 322 isolates of fungi belonging to four phyla from maize (Zea mays L.) plants. Plants were sampled over two growing seasons (2014 and 2015) in two regions of NZ. Morphological and molecular (ITS rDNA sequencing) techniques were used to identify the fungi. The most common genera recovered were Fusarium, followed by Alternaria, Trichoderma, Epicoccum, Mucor, Penicillium and Cladosoprium spp. Of the Acomycota isolates, 33 genera from 6 classes were recovered.
