Eucalyptus microfungi known from culture. 1. Cladoriella and Fulvoflamma genera nova, with notes on some other poorly known taxa

A study of microfungi associated with living Eucalyptus leaves and leaf litter revealed several novel and interesting taxa. Cladoriella eucalypti gen. et sp. nov. is described as a Cladosporium-like genus associated with litter collected in South Africa, while Fulvoflamma eucalypti gen. et. sp. nov. is newly described from leaf litter collected in Spain. Beta-conidia are newly reported for species of Pestalotiopsis, namely Pestalotiopsis disseminata in New Zealand, and a Pestalotiopsis sp. from Colombia. Satchmopsis brasiliensis is reported from litter in Colombia and Indonesia, while Torrendiella eucalypti is reported from leaf litter in Indonesia, and shown to have a Sporothrix-like anamorph. Leptospora rubella is reported from living Eucalyptus leaves in Colombia, where it is associated with leaf spots of Mycosphaerella longibasalis, while Macrohilum eucalypti is reported from leaf spots of Eucalyptus in New Zealand

MycoBank gearing up for new horizons.

MycoBank, a registration system for fungi established in 2004 to capture all taxonomic novelties, acts as a coordination hub between repositories such as Index Fungorum and Fungal Names. Since January 2013, registration of fungal names is a mandatory requirement for valid publication under the International Code of Nomenclature for algae, fungi and plants (ICN). This review explains the database innovations that have been implemented over the past few years, and discusses new features such as advanced queries, registration of typification events (MBT numbers for lecto, epi- and neotypes), the multi-lingual database interface, the nomenclature discussion forum, annotation system, and web services with links to third parties. MycoBank has also introduced novel identification services, linking DNA sequence data to numerous related databases to enable intelligent search queries. Although MycoBank fills an important void for taxon registration, challenges for the future remain to improve links between taxonomic names and DNA data, and to also introduce a formal system for naming fungi known from DNA sequence data only. To further improve the quality of MycoBank data, remote access will now allow registered mycologists to act as MycoBank curators, using Citrix software

EMbaRC - A European Consortium of Microbial Resource Centres for Science & lnnovation

EMbaRC is an EU project funded under the Seventh Framework Programme, Research lnfrastructures action. lt aims to improve, coordinate and validate microbial Biological Resource Centres (BRC) delivery to European and lnternational researchers from both public and private sectors. Apart from the networking and research activities, EMbaRC offers EU-supported grants for Trans-national Access opportunities. Scientists who carry out research in Europe or Associated Countries can use EMbaRC infrastructures to support part of their research project. ln this presentation, the main achievements of the first year will be summarized. Networking activities allow i) an estimation of overlapping/uniqueness between the consortium holdings, ii) a deep analysis of strain deposit after publication, iii) a review of the training offered by the consortium in the collection management and associated tools (identification, data management, etc.), iv) an harmonisation of the quality manual, v) a first draft for a biosecurity code, and vi) establish the basis of a common strategy to increase the sustainability of BRCs. Joint Research activities focused in particular on storage of recalcitrant strains, DNA storage and species identification by new methods like mass spectrometry ... ln parallel, success stories are being gathered to support the idea that microbial collections contribute to the bioeconomy. Such achievements can be a way to increase the sustainability of collections, and some of them will be presented

EMbaRC will cover the bench fees, travel and subsistence costs. This unique opportunity for training in collection management, identification of bacteria and fungi by stateof-the-art techniques or phenotypic screening of a collection of strains is organised with the support of the Seventh Framework Programme, Research lnfrastructures Action

The Amsterdam Declaration on Fungal Nomenclature

The Amsterdam Declaration on Fungal Nomenclature was agreed at an international symposium convened in Amsterdam on 19–20 April 2011 under the auspices of the International Commission on the Taxonomy of Fungi (ICTF). The purpose of the symposium was to address the issue of whether or how the current system of naming pleomorphic fungi should be maintained or changed now that molecular data are routinely available. The issue is urgent as mycologists currently follow different practices, and no consensus was achieved by a Special Committee appointed in 2005 by the International Botanical Congress to advise on the problem. The Declaration recognizes the need for an orderly transitition to a single-name nomenclatural system for all fungi, and to provide mechanisms to protect names that otherwise then become endangered. That is, meaning that priority should be given to the first described name, except where that is a younger name in general use when the first author to select a name of a pleomorphic monophyletic genus is to be followed, and suggests controversial cases are referred to a body, such as the ICTF, which will report to the Committee for Fungi. If appropriate, the ICTF could be mandated to promote the implementation of the Declaration. In addition, but not forming part of the Declaration, are reports of discussions held during the symposium on the governance of the nomenclature of fungi, and the naming of fungi known only from an environmental nucleic acid sequence in particular. Possible amendments to the Draft BioCode (2011) to allow for the needs of mycologists are suggested for further consideration, and a possible example of how a fungus only known from the environment might be described is presented

Fusarium: more than a node or a foot-shaped basal cell

Recent publications have argued that there are potentially serious consequences for researchers in recognising distinct genera in the terminal fusarioid clade of the family Nectriaceae. Thus, an alternate hypothesis, namely a very broad concept of the genus Fusarium was proposed. In doing so, however, a significant body of data that supports distinct genera in Nectriaceae based on morphology, biology, and phylogeny is disregarded. A DNA phylogeny based on 19 orthologous protein-coding genes was presented to support a very broad concept of Fusarium at the F1 node in Nectriaceae. Here, we demonstrate that re-analyses of this dataset show that all 19 genes support the F3 node that represents Fusarium sensu stricto as defined by F. sambucinum (sexual morph synonym Gibberella pulicaris). The backbone of the phylogeny is resolved by the concatenated alignment, but only six of the 19 genes fully support the F1 node, representing the broad circumscription of Fusarium. Furthermore, a re-analysis of the concatenated dataset revealed alternate topologies in different phylogenetic algorithms, highlighting the deep divergence and unresolved placement of various Nectriaceae lineages proposed as members of Fusarium. Species of Fusarium s. str. are characterised by Gibberella sexual morphs, asexual morphs with thin- or thick-walled macroconidia that have variously shaped apical and basal cells, and trichothecene mycotoxin production, which separates them from other fusarioid genera. Here we show that the Wollenweber concept of Fusarium presently accounts for 20 segregate genera with clear-cut synapomorphic traits, and that fusarioid macroconidia represent a character that has been gained or lost multiple times throughout Nectriaceae. Thus, the very broad circumscription of Fusarium is blurry and without apparent synapomorphies, and does not include all genera with fusarium-like macroconidia, which are spread throughout Nectriaceae (e.g., Cosmosporella, Macroconia, Microcera). In this study four new genera are introduced, along with 18 new species and 16 new combinations. These names convey information about relationships, morphology, and ecological preference that would otherwise be lost in a broader definition of Fusarium. To assist users to correctly identify fusarioid genera and species, we introduce a new online identification database, Fusarioid-ID, accessible at www.fusarium.org. The database comprises partial sequences from multiple genes commonly used to identify fusarioid taxa (act1, CaM, his3, rpb1, rpb2, tef1, tub2, ITS, and LSU). In this paper, we also present a nomenclator of names that have been introduced in Fusarium up to January 2021 as well as their current status, types, and diagnostic DNA barcode data. In this study, researchers from 46 countries, representing taxonomists, plant pathologists, medical mycologists, quarantine officials, regulatory agencies, and students, strongly support the application and use of a more precisely delimited Fusarium (= Gibberella) concept to accommodate taxa from the robust monophyletic node F3 on the basis of a well-defined and unique combination of morphological and biochemical features. This F3 node includes, among others, species of the F. fujikuroi, F. incarnatum-equiseti, F. oxysporum, and F. sambucinum species complexes, but not species of Bisifusarium [F. dimerum species complex (SC)], Cyanonectria (F. buxicola SC), Geejayessia (F. staphyleae SC), Neocosmospora (F. solani SC) or Rectifusarium (F. ventricosum SC). The present study represents the first step to generating a new online monograph of Fusarium and allied fusarioid genera (www.fusarium.org)

Ultrastructure of the ascus apical apparatus in Leotia lubrica and some Geoglossaceae (Leotiales, Ascomycotina)

The ultrastructure of the apical apparatus and lateral ascus wall is compared in Leotia lubrica and five species currently placed in the Geoglossaceae. The lateral ascus wall consists of two layers, of which the inner one increases in thickness in the apical apparatus. Considerable differences in substructure of both layers are described. On the basis of general morphology of the apical apparatus, structure and PA-TCH-SP reactivity of the apical thickening and annulus, and occurrence of an annular protrusion four main categories are distinguished. A reactive annulus is demonstrated in the apical apparatus of all species, including L. lubrica. The species studied are arranged as follows: Category 1a. Geoglossum nigritum and G. cookeianum; 1b. Trichoglossum hirsutum; 2. Leotia lubrica; 3. Microglossum viride; 4. Mitrula paludosa. Most fundamental is considered the position of the annulus in the apical thickening, either fully (category 1) or partly (2—4) occupying the apical thickening, either associated with an annular protrusion (3, 4) or not (1, 2). The data on the ultrastructure of the ascus apical apparatus and lateral wall, and mode of dehiscence indicate that L. lubrica takes an isolated position, distant from the other Leotioideae (including Ombrophiloideae) and the Geoglossaceae. Geoglossum, Trichoglossum, and Microglossum can best b

Ultrastructure of the apical apparatus of asci in Ombrophila violacea, Neobulgaria pura and Bulgaria inquinans (Leotiales)

The ultrastructure of the apical apparatus in asci of three species of the Ombrophiloideae (Leotiaceae) is compared. Ombrophila violacea and Neobulgaria pura show similarities in morphology and maturation pattern of the apical apparatus, suggesting a close relation between these species. In these respects and in development of the ascospore wall Bulgaria inquinans differs considerably from O. violacea and N. pura
