Epitypification of Fusarium oxysporum – clearing the taxonomic chaos Naturalis
Lombard, L.; Sandoval-Denis, M.; Lamprecht, S.C.; Crous, P.W..
Fusarium oxysporum is the most economically important and commonly encountered species of Fusarium. This soil-borne fungus is known to harbour both pathogenic (plant, animal and human) and non-pathogenic strains. However, in its current concept F. oxysporum is a species complex consisting of numerous cryptic species. Identification and naming these cryptic species is complicated by multiple subspecific classification systems and the lack of living ex-type material to serve as basic reference point for phylogenetic inference. Therefore, to advance and stabilise the taxonomic position of F. oxysporum as a species and allow naming of the multiple cryptic species recognised in this species complex, an epitype is designated for F. oxysporum. Using multi-locus...

New species of Cladosporium associated with human and animal infections Naturalis
Sandoval-Denis, M.; Gené, J.; Sutton, N.P. Wiederhold, J.F. Cano-Lira, J. Guarro, D.A.; Wiederhold , N.P.; Cano-Lira, J.F.; Guarro, J..
Cladosporium is mainly known as a ubiquitous environmental saprobic fungus or plant endophyte, and to date, just a few species have been documented as etiologic agents in vertebrate hosts, including humans. In the present study, 10 new species of the genus were isolated from human and animal clinical specimens from the USA. They are proposed and characterized on the basis of their morphology and a molecular phylogenetic analysis using DNA sequences from three loci (the ITS region of the rDNA, and partial fragments of the translation elongation factor 1-alpha and actin genes). Six of those species belong to the C. cladosporioides species complex, i.e., C. alboflavescens, C. angulosum, C. anthropophilum, C. crousii, C. flavovirens and C. xantochromaticum,...

Redefining Microascus, Scopulariopsis and allied genera Naturalis
Sandoval-Denis, M.; Gené, J.; Sutton, D.A.; Cano-Lira , J.F.; Hoog, G.S. de; Decock, C.A.; Wiederhold, N.P.; Guarro, J..
The genera Microascus and Scopulariopsis comprise species commonly isolated from soil, decaying plant material and indoor environments. A few species are also recognised as opportunistic pathogens of insects and animals, including humans. In the past, the taxonomy of these fungi has been based on morphology only. With the aim to clarify the taxonomy and phylogeny of these fungi, we studied a large set of clinical and environmental isolates, including the available ex-type strains of numerous species, by means of morphological, physiological and molecular analyses. Species delineation was assessed under the Genealogical Phylogenetic Species Recognition (GCPSR) criterion using DNA sequence data of four loci (ITS region, and fragments of rDNA LSU, translation...

Removing chaos from confusion: assigning names to common human and animal pathogens in Neocosmospora Naturalis
Sandoval-Denis, M.; Crous, P.W..
The genus Neocosmospora encompasses highly prevalent and aggressive human and animal fungal pathogens. Here we assign formal descriptions and Latin binomials to some of the most clinically relevant phylogenetic species of the genus. Three new species, named Neocosmospora catenata, N. gamsii and N. suttoniana (previously assigned to the informal names ‘Fusarium’ solani species complex (FSSC) lineages, FSSC 43, FSSC 7 and FSSC 20, respectively) are described on the basis of multilocus phylogenetic analyses (using EF-1α, ITS, LSU and RPB2 loci) and morphological characters. Lineage FSSC 9 is conspecific with the ex-type strain of Cylindrocarpon tonkinense, thus the new combination Neocosmospora tonkinensis is proposed. In addition, and based on the latest...

Seiridium (Sporocadaceae): an important genus of plant pathogenic fungi Naturalis
Bonthond, G.; Sandoval-Denis, M.; Groenewald, J.Z.; Crous, P.W..
The genus Seiridium includes multiple plant pathogenic fungi well-known as causal organisms of cankers on Cupressaceae. Taxonomically, the status of several species has been a topic of debate, as the phylogeny of the genus remains unresolved and authentic ex-type cultures are mostly absent. In the present study, a large collection of Seiridium cultures and specimens from the CBS and IMI collections was investigated morphologically and phylogenetically to resolve the taxonomy of the genus. These investigations included the type material of the most important Cupressaceae pathogens, Seiridium cardinale, S. cupressi and S. unicorne. We constructed a phylogeny of Seiridium based on four loci, namely the ITS rDNA region, and partial translation elongation...

Symptomatic Citrus trees reveal a new pathogenic lineage in Fusarium and two new Neocosmospora species Naturalis
Sandoval-Denis, M.; Guarnaccia, V.; Polizzi, G.; Crous, P.W..
The diversity of fusaria in symptomatic Citrus trees in Greece, Italy and Spain was evaluated using morphological and molecular multi-locus analyses based on fragments of the calmodulin (CAM), intergenic spacer region of the rDNA (IGS), internal transcribed spacer region of the rDNA (ITS), large subunit of the rDNA (LSU), RNA polymerase largest subunit (RPB1), RNA polymerase second largest subunit (RPB2), translation elongation factor 1-alpha (EF-1α) and beta-tubulin (TUB) genes. A total of 11 species (six Fusarium spp., and five Neocosmospora spp.) were isolated from dry root rot, crown, trunk or twig canker or twig dieback of citrus trees. The most commonly isolated species were Fusarium sarcochroum, F. oxysporum and Neocosmospora solani. Three new...
