A comprehensive molecular phylogeny of the Mortierellales (Mortierellomycotina) based on nuclear ribosomal DNA Naturalis
Wagner, L.; Stielow, B.; Hoffmann, K.; Petkovits, T.; Papp, T.; Vágvölgyi, C.; Hoog, G.S. de; Verkley, G.; Voigt, K..
The basal fungal order Mortierellales constitutes one of the largest orders in the basal lineages. This group consists of one family and six genera. Most species are saprobic soil inhabiting fungi with the ability of diverse biotransformations or the accumulation of unsaturated fatty acids, making them attractive for biotechnological applications. Only few studies exist aiming at the revelation of the evolutionary relationships of this interesting fungal group. This study includes the largest dataset of LSU and ITS sequences for more than 400 specimens containing 63 type or reference strains. Based on a LSU phylogram, fungal groups were defined and evaluated using ITS sequences and morphological features. Traditional morphology-based classification schemes...

A new species of Myrothecium Naturalis
Rao, Vasant; Hoog, G.S. de.
During a collecting trip for microfungi in Andhra Pradesh, India, the senior author collected an unusual fungus showing characteristics of both Myrothecium Tode: Fr. and Sarcopodium Ehrenb. Recent taxonomic accounts are available for both genera (e.g. Tulloch, 1972; Sutton, 1973, 1981; Ellis, 1971, 1976; Matsushima, 1971, 1975, 1981; Nag Raj & George, 1960). The genera comprise sporodochial or somewhat synnematous hyphomycetes forming conidia in slimy masses from densely aggregated phialides. In Sarcopodium the hymenium is interspersed with often coiled, branched, pigmented, mostly echinulate setae, whereas in Myrothecium the setae, if present, occur at the periphery of the conidioma and are straight, unbranched, hyaline or pale, and usually...

DNA barcoding in Mucorales: an inventory of biodiversity Naturalis
Walther, G.; Pawłowska, J.; Alastruey-Izquierdo, A.; Wrzosek, M.; Rodriguez-Tudela, J.L.; Dolatabadi, S.; Chakrabarti, A.; Hoog, G.S. de.
The order Mucorales comprises predominantly fast-growing saprotrophic fungi, some of which are used for the fermentation of foodstuffs but it also includes species known to cause infections in patients with severe immune or metabolic impairments. To inventory biodiversity in Mucorales ITS barcodes of 668 strains in 203 taxa were generated covering more than two thirds of the recognised species. Using the ITS sequences, Molecular Operational Taxonomic Units were defined by a similarity threshold of 99 %. An LSU sequence was generated for each unit as well. Analysis of the LSU sequences revealed that conventional phenotypic classifications of the Mucoraceae are highly artificial. The LSU- and ITS-based trees suggest that characters, such as rhizoids and...

Notes some fungicolous Hyphomycetes and their relatives Naturalis
Hoog, G.S. de.
Cladobotryum Nees ex Steud. is redefined and two new species are added to this genus. The uredinicolous genus Colletoconis gen. nov. is segregated from Gloeosporium Desm. & Mont, to accommodate G. aecidiophilum Speg. Engyodontium gen. nov. is erected for Rhinotrichum parvisporum Petch and a similar fungus. The monotypic genus Helminthophora Bon. is redescribed. Sympodiophora G. Arnold is combined with the earlier described genus Pseudohansfordia G. Arnold; eight new combinations are proposed. One new species is added to Denticularia Deighton and two to Sporothrix Hektoen & Perkins; in addition, two new combinations are proposed in the latter genus. A list of doubtful and excluded species formerly classified in the treated genera is given.

On the identity of Curvularia subulata Naturalis
Tan, C.S.; Hoog, G.S. de.
Occasionally fungal strains have been received by the ‘Centraalbureau voor Schimmelcultures’ under the name Curvularia subulata (Nees) Boedijn. This name also turns up in the literature (Corbetta, 1965; Jalal & al., 1984). A culture, carrying this name and deposited recently at the CBS, was indistinguishable from Curvularia lunata. Since the epithet ‘subulata’ is older than ‘lunata’, a study was made to establish the identity of Curvularia subulata. The binomial Curvularia subulata was mentioned by Gilman (1945), with the cited author’s names ‘(Nees) Boedijn’ and making reference to Boedijn’s (1983) paper on Curvularia. However, neither in this article, nor in any other article Boedijn’s personal notes, maintained at the Rijksherbarium at Leiden, no...

Stielow, J.B.; Lévesque, C.A.; Seifert, K.A.; Meyer, W.; Irinyi, L.; Smits, D.; Renfurm, R.; Verkley, G.J.M.; Groenewald, M.; Chaduli, D.; Lomascolo, A.; Welti, S.; Lesage-Meessen, L.; Favel, A.; Al-Hatmi, A.M.S.; Damm, U.; Yilmaz, N.; Houbraken, J.; Lombard, L.; Quaedvlieg, W.; Binder, M.; Vaas, L.A.I.; Vu, D.; Yurkov, A.; Begerow, D.; Roehl, O.; Guerreiro, M.; Fonseca, A.; Samerpitak, K.; Diepeningen, A.D. van; Dolatabadi, S.; Moreno, L.F.; Casaregola, S.; Mallet, S.; Jacques, N.; Roscini, L.; Egidi, E.; Bizet, C.; Garcia-Hermoso, D.; Martin, M.P.; Deng, S.; Groenewald, J.Z.; Boekhout, T.; Beer, Z.W. de; Barnes, I.; Duong, T.A.; Wingfield, M.J.; Hoog, G.S. de; Crous, P.W.; Lewis, C.T.; Hambleton, S.; Moussa, T.A.A.; Al-Zahrani, H.S.; Almaghrabi, O.A.; Louis-Seize, G.; Assabgui, R.; McCormick, W.; Omer, G.; Dukik, K.; Cardinali, G.; Eberhardt, U.; Vries, M. de; Robert, V..
The aim of this study was to assess potential candidate gene regions and corresponding universal primer pairs as secondary DNA barcodes for the fungal kingdom, additional to ITS rDNA as primary barcode. Amplification efficiencies of 14 (partially) universal primer pairs targeting eight genetic markers were tested across > 1 500 species (1 931 strains or specimens) and the outcomes of almost twenty thousand (19 577) polymerase chain reactions were evaluated. We tested several well-known primer pairs that amplify: i) sections of the nuclear ribosomal RNA gene large subunit (D1–D2 domains of 26/28S); ii) the complete internal transcribed spacer region (ITS1/2); iii) partial β-tubulin II (TUB2); iv) γ-actin (ACT); v) translation elongation factor 1-α (TEF1α);...

Phylogeny of Sarocladium (Hypocreales) Naturalis
Giraldo, A.; Gené, J.; Sutton, D.A.; Madrid, H.; Hoog, G.S. de; Cano, J.; Decock, C.; Crous, P.W.; Guarro, J..
The circumscription of the genus Acremonium (Hypocreales) was recently reviewed on the basis of a DNA phylogenetic study. Several species were subsequently transferred to Sarocladium, but the relationships between both genera remained unresolved. Based on multilocus phylogenetic inferences combined with phenotypic data, we have revised the species concepts within Sarocladium and some genetically related species of Acremonium. As a result of these studies, six species are described as new, viz. S. bifurcatum, S. gamsii, S. hominis, S. pseudostrictum, S. subulatum and S. summerbellii. In addition, the new combinations S. implicatum and S. terricola are proposed for A. implicatum and A. terricola, respectively. Sarocladium attenuatum is confirmed as synonym...

Phylogeography and evolutionary patterns in Sporothrix spanning more than 14 000 human and animal case reports Naturalis
Zhang, Y.; Hagen, F.; Stielow, B.; Rodrigues, A.M.; Samerpitak, K.; Zhou, X.; Feng, P.; Yang, L.; Chen, M.; Deng, S.; Li, S.; Liao, W.; Li, R.; Li, F.; Meis, J.F.; Guarro, J.; Teixeira, M.; Al-Zahrani, H.S.; Pires de Camargo, Z.; Zhang, L.; Hoog, G.S. de.
Pathology to vertebrate hosts has emerged repeatedly in the order Ophiostomatales. Occasional infections have been observed in Sporothrix mexicana at a low level of virulence, while the main pathogenic species cluster in a derived clade around S. schenckii s.str. In this paper, phylogeny and epidemiology of the members of this clade were investigated for 99 clinical and 36 environmental strains using four genetic loci, viz. rDNA ITS and partial CAL, TEF1, and TEF3; data are compared with amplified fragment length polymorphism (AFLP) genotyping. The four main species of the pathogenic clade were recognised. The species proved to show high degrees of endemicity, which enabled interpretation of literature data where live material or genetic information is...

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...

Revision of agents of black-grain eumycetoma in the order Pleosporales Naturalis
Ahmed, S.A.; Sande, W.W.J. van de; Stevens, D.A.; Fahal, A.; Diepeningen, A.D. van; Menken, S.B.J.; Hoog, G.S. de.
Eumycetoma is a chronic fungal infection characterised by large subcutaneous masses and the presence of sinuses discharging coloured grains. The causative agents of black-grain eumycetoma mostly belong to the orders Sordariales and Pleosporales. The aim of the present study was to clarify the phylogeny and taxonomy of pleosporalean agents, viz. Madurella grisea, Medicopsis romeroi (syn.: Pyrenochaeta romeroi), Nigrograna mackinnonii (syn. Pyrenochaeta mackinnonii), Leptosphaeria senegalensis, L. tompkinsii, and Pseudochaetosphaeronema larense. A phylogenetic analysis based on five loci was performed: the Internal Transcribed Spacer (ITS), large (LSU) and small (SSU) subunit ribosomal RNA, the second largest RNA polymerase subunit (RPB2), and translation...

Taxonomy and epidemiology of Mucor irregularis, agent of chronic cutaneous mucormycosis Naturalis
Lu, X.-L.; Najafzadeh, M.J.; Dolatabadi, S.; Ran, Y.-P.; Shen, Y.-N.; Li, C.-Y.; Xi, L.-Y.; Hao, F.; Zhang, Q.-Q.; Li, R.-Y.; Hu, Z.-M.; Lu, G.-X.; Wang, J.-J.; Drogari-Apiranthitou, M.; Klaassen, C.; Meis, J.F.; Hagen, F.; Liu, W.-D.; Hoog, G.S. de.
Mucormycosis usually presents as a progressive infection with significant angio-invasion. Mucormycosis due to Mucor irregularis (formerly Rhizomucor variabilis var. variabilis), however, is exceptional in causing chronic cutaneous infection in immunocompetent humans, ultimately leading to severe morbidity if left untreated. More than 90 % of the cases known to date were reported from Asia, mainly from China. The nearest neighbour of M. irregularis is the saprobic species M. hiemalis. The aim of this study was to evaluate the taxonomic position, epidemiology, and intra- and inter-species diversity of M. irregularis based on 21 strains (clinical n = 17) by multilocus analysis using ITS, LSU, RPB1 and RPB2 genes, compared to results of cluster analysis with...

The family structure of the Mucorales: a synoptic revision based on comprehensive multigene-genealogies Naturalis
Hoffmann, K.; Pawłowska, J.; Walther, G.; Wrzosek, M.; Hoog, G.S. de; Benny, G.L.; Kirk, P.M.; Voigt, K..
The Mucorales (Mucoromycotina) are one of the most ancient groups of fungi comprising ubiquitous, mostly saprotrophic organisms. The first comprehensive molecular studies 11 yr ago revealed the traditional classification scheme, mainly based on morphology, as highly artificial. Since then only single clades have been investigated in detail but a robust classification of the higher levels based on DNA data has not been published yet. Therefore we provide a classification based on a phylogenetic analysis of four molecular markers including the large and the small subunit of the ribosomal DNA, the partial actin gene and the partial gene for the translation elongation factor 1-alpha. The dataset comprises 201 isolates in 103 species and represents about one...

The hyphomycete genus Engyodontium a link between Verticillium and Aphanocladium Naturalis
Gams, W.; Hoog, G.S. de; Samson, R.A.; Evans, H.C..
Sporotrichum aranearum Cavara is redescribed from living cultures and found to have two kinds of conidiogenesis: phialidic and polyblastic. The latter type which is most conspicuous in this fungus, fits the genus Engyodontium de Hoog. This genus is considered to be a link between Verticillium and Aphanocladium and its generic diagnosis is extended to include both progressive and retrogressive formation of new conidiiferous pegs. Sporothrix (Tritirachium) rectidentatum (Matsushima) de Hoog and Cephalosporium aranearum Petch, in which some polyblastic conidiogenous cells with narrow denticles were also found, are transferred to Engyodontium. For the latter species the new name E. arachnophilum is proposed. The genus now comprises six species, including E....
