Diversity of mycobiota in colonies of different species of leaf-cutting ants and sampling sites across Argentina
Provedor de dados: Ecología Austral
Autores: Marfetan,Jorge A; Folgarait,Patricia J.
Attine ants are a monophyletic group comprising more than 230 species, distributed exclusively in the New World. All higher Attini ants depend on the cultivation of fungus gardens for food, and those gardens are continuously exposed to alien microorganisms. The present work describes, for the first time, the composition, relative frequency and the richness of the fungal species comprising the mycobiota from the garden of the most abundant Acromyrmex species from different regions of Argentina. We also compared, using a multivariate approach, the mycobiota composition with the purpose of testing two hypotheses: 1) whether mycobiota is defined by the ant species, or 2) whether mycobiota is determined by the geographical region. We found that each fungal...

Redefining Microascus, Scopulariopsis and allied genera
Provedor de dados: Naturalis Digital Academic Repository
Autores: 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...

Roselliniella revealed as an overlooked genus of Hypocreales, with the description of a second species on parmelioid lichens
Provedor de dados: Naturalis Digital Academic Repository
Autores: Hawksworth, D.L.; Millanes, A.M.; Wedin, M.
Based on newly obtained 28S rDNA sequences from Roselliniella atlantica and R. euparmeliicola sp. nov., the genus Roselliniella has to be placed in Hypocreales and not in Sordariales; however, the family placement could not be resolved from the sequences obtained. The mature ascospores are single-celled and brown, but young ascospores are hyaline and sometimes have a median septum. The new species occurs on a Parmelia s.str. species in China, and differs in 24 nucleotide substitution positions in the nu-LSU rDNA region and ascospore size from R. atlantica. In this case, small variations in ascospore sizes and shape prove to be phylogenetically and taxonomically informative. The two species occur in the same clade with 95 % jack-knife support. Roselliniella...

The Colletotrichum gigasporum species complex
Provedor de dados: Naturalis Digital Academic Repository
Autores: Liu, F.; Cai, L.; Crous, P.W.; Damm, U.
In a preliminary analysis, 21 Colletotrichum strains with large conidia preserved in the CBS culture collection clustered with a recently described species, C. gigasporum, forming a clade distinct from other currently known Colletotrichum species complexes. Multi-locus phylogenetic analyses (ITS, ACT, TUB2, CHS-1, GAPDH) as well as each of the single-locus analyses resolved seven distinct species, one of them being C. gigasporum. Colletotrichum gigasporum and its close allies thus constitute a previously unknown species complex with shared morphological features. Five of the seven species accepted in the C. gigasporum species complex are described here as novel species, namely C. arxii, C. magnisporum, C. pseudomajus, C. radicis and C. vietnamense. A...

Asperisporium and Pantospora (Mycosphaerellaceae): epitypifications and phylogenetic placement
Provedor de dados: Naturalis Digital Academic Repository
Autores: Minnis, A.M.; Kennedy, A.H.; Grenier, D.B.; Rehner, S.A.; Bischoff, J.F.
The species-rich family Mycosphaerellaceae contains considerable morphological diversity and includes numerous anamorphic genera, many of which are economically important plant pathogens. Recent revisions and phylogenetic research have resulted in taxonomic instability. Ameliorating this problem requires phylogenetic placement of type species of key genera. We present an examination of the type species of the anamorphic Asperisporium and Pantospora. Cultures isolated from recent port interceptions were studied and described, and morphological studies were made of historical and new herbarium specimens. DNA sequence data from the ITS region and n LSU were generated from these type species, analysed phylogenetically, placed into an evolutionary context...

Trichoderma (Hypocrea) species with green ascospores from China
Provedor de dados: Naturalis Digital Academic Repository
Autores: Zhu, Z.X.; Zhuang, W.Y.
Stromata of Trichoderma species having green ascospores were collected in various regions of China. Based on morphology of the sexual and asexual morph, culture characteristics, and sequence analyses of rpb2 and tef1 genes, 17 species with green ascospores were identified. Among them, Trichoderma rosulatum, T. rufobrunneum and T. stipitatum are described as new species, and seven other species are reported for the first time from China. Trichoderma rosulatum produces small bright yellow or pale greenish stromata with dense dark green ostioles and gliocladium-like conidiophores, shows a close relationship to T. thelephoricola, and belongs to the Chlorospora clade. Trichoderma rufobrunneum, which typically forms reddish brown stromata, is recognised as a...

Juglanconis gen. nov. on Juglandaceae, and the new family Juglanconidaceae (Diaporthales)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Voglmayr, H.; Castlebury, L.A.; Jaklitsch, W.M.
Molecular phylogenetic analyses of ITS-LSU rDNA sequence data demonstrate that Melanconis species occurring on Juglandaceae are phylogenetically distinct from Melanconis s.str., and therefore the new genus Juglanconis is described. Morphologically, the genus Juglanconis differs from Melanconis by light to dark brown conidia with irregular verrucae on the inner surface of the conidial wall, while in Melanconis s.str. they are smooth. Juglanconis forms a separate clade not affiliated with a described family of Diaporthales, and the family Juglanconidaceae is introduced to accommodate it. Data of macro- and microscopic morphology and phylogenetic multilocus analyses of partial nuSSU-ITS-LSU rDNA, cal, his, ms204, rpb1, rpb2, tef1 and tub2 sequences revealed...

Two new classes of Ascomycota: Xylobotryomycetes and Candelariomycetes
Provedor de dados: Naturalis Digital Academic Repository
Autores: Voglmayr, H.; Fournier, J.; Jaklitsch, W.M.
Phylogenetic analyses of a combined DNA data matrix containing nuclear small and large subunits (nSSU, nLSU) and mitochondrial small subunit (mtSSU) ribosomal RNA and the largest and second largest subunits of the RNA polymerase II (rpb1, rpb2) of representative Pezizomycotina revealed that the enigmatic genera Xylobotryum and Cirrosporium form an isolated, highly supported phylogenetic lineage within Leotiomyceta. Acknowledging their morphological and phylogenetic distinctness, we describe the new class Xylobotryomycetes, containing the new order Xylobotryales with the two new families Xylobotryaceae and Cirrosporiaceae. The two currently accepted species of Xylobotryum, X. andinum and X. portentosum, are described and illustrated by light and scanning...

Resolution of morphology-based taxonomic delusions: Acrocordiella, Basiseptospora, Blogiascospora, Clypeosphaeria, Hymenopleella, Lepteutypa, Pseudapiospora, Requienella, Seiridium and Strickeria
Provedor de dados: Naturalis Digital Academic Repository
Autores: Jaklitsch, W.M.; Gardiennet, A.; Voglmayr, H.
Fresh material, type studies and molecular phylogeny were used to clarify phylogenetic relationships of the nine genera Acrocordiella, Blogiascospora, Clypeosphaeria, Hymenopleella, Lepteutypa, Pseudapiospora, Requienella, Seiridium and Strickeria. At first sight, some of these genera do not seem to have much in common, but all were found to belong to the Xylariales, based on their generic types. Thus, the most peculiar finding is the phylogenetic affinity of the genera Acrocordiella, Requienella and Strickeria, which had been classified in the Dothideomycetes or Eurotiomycetes, to the Xylariales. Acrocordiella and Requienella are closely related but distinct genera of the Requienellaceae. Although their ascospores are similar to those of Lepteutypa,...

Phylogeny and taxonomic revision of the Planistromellaceae including its coelomycetous anamorphs: contributions towards a monograph of the genus Kellermania
Provedor de dados: Naturalis Digital Academic Repository
Autores: Minnis, A.M.; Kennedy, A.H.; Grenier, D.B.; Palm, M.E.; Rossman, A.Y.
The core species of the family Planistromellaceae are included in the teleomorphic genera Planistroma and Planistromella and the connected anamorphic, coelomycetous genera Alpakesa, Kellermania, and Piptarthron. These genera have been defined primarily on the basis of ascospore septation or number of conidial appendages. Due to a lack of DNA sequence data, phylogenetic placement of these genera within the Dothideomycetes, evaluation of monophyly, and questions about generic boundaries could not be adequately addressed in the past. Isolates of nearly all of the known species in these genera were studied genetically and morphologically. DNA sequence data were generated for the nSSU, ITS, nLSU, and RPB1 markers and analysed phylogenetically. These results...

Phylogenetic and taxonomic revision of Lopadostoma
Provedor de dados: Naturalis Digital Academic Repository
Autores: Jaklitsch, W.M.; Fournier, J.; Rogers, J.D.; Voglmayr, H.
The genus Lopadostoma (Xylariaceae, Xylariales) is revised. Most species formerly assigned to Lopadostoma do not belong to the genus. Twelve species are herein recognised, of which two are only known from morphology. Ten species, of which six (L. americanum, L. fagi, L. insulare, L. lechatii, L. meridionale and L. quercicola) are newly described, are characterised by both morphology and DNA phylogeny using LSU, ITS and rpb2 sequences. Morphologically, ecologically and phylogenetically Lopadostoma is a well-defined genus comprising exclusively species with pustular pseudostroma development in bark of angiospermous trees. Phaeosperma ailanthi, Phaeosperma dryophilum and Sphaeria linosperma are combined in Lopadostoma. Lopadostoma gastrinum is neotypified and...

New primers for promising single-copy genes in fungal phylogenetics and systematics
Provedor de dados: Naturalis Digital Academic Repository
Autores: Schmitt, I.; Crespo, A.; Divakar, P.K.; Fankhauser, J.D.; Herman-Sackett, E.; Kalb, K.; Nelsen, M.P.; Nelson, N.A.; Rivas-Plata, E.; Shimp, A.D.; Widhelm, T.; Lumbsch, H.T.
Developing powerful phylogenetic markers is a key concern in fungal phylogenetics. Here we report degenerate primers that amplify the single-copy genes Mcm7 (MS456) and Tsr1 (MS277) across a wide range of Pezizomycotina (Ascomycota). Phylogenetic analyses of 59 taxa belonging to the Eurotiomycetes, Lecanoromycetes, Leotiomycetes, Lichinomycetes and Sordariomycetes, indicate the utility of these loci for fungal phylogenetics at taxonomic levels ranging from genus to class. We also tested the new primers in silico using sequences of Saccharomycotina, Taphrinomycotina and Basidiomycota to predict their potential of amplifying widely across the Fungi. The analyses suggest that the new primers will need no, or only minor sequence modifications to amplify...

Adaptations of lichens to conditions in tropical forests of South-East Asia and their taxonomic implications
Provedor de dados: Naturalis Digital Academic Repository
Autores: Wolseley, P.A.; Hawksworth, D.L.
Lichens are fungi with a specialized nutritional mode involving algae, or cyanobacteria, or both. Classification is based on the fungal partner, and around 13 500 species are known. The association is ancient, and the first ascomycete fungi with fruit bodies may have been lichenized. Adaptations to tropical habitats include extensive utilization of trentepohlioid algae, the production of large multi-celled spores capable of forming numerous germ tubes, and water-repellant hydophobins coating internal cell walls. Many tropical groups lack modern monographs and numerous new species are discovered in detailed studies. Lichens merit more attention in the tropics as bioindicators of habitat disturbance.

Generic circumscriptions in Geoglossomycetes
Provedor de dados: Naturalis Digital Academic Repository
Autores: Hustad, V.P.; Miller, A.N.; Dentinger, B.T.M.; Cannon, P.F.
The class Geoglossomycetes is a recently created class of Ascomycota, currently comprised of one family (Geoglossaceae) and five genera (Geoglossum, Nothomitra, Sarcoleotia, Thuemenidium and Trichoglossum). These fungi, commonly known as earth tongues, have long been a subject of mycological research. However, the taxonomy within the group has historically been hindered by the lack of reliable morphological characters, uncertain ecological associations, and the inability to grow these fungi in culture. The phylogenetic relationships of Geoglossomycetes were investigated by conducting maximum likelihood and Bayesian analyses using a 4-gene dataset (ITS, LSU, MCM7, RPB1). Five well-supported monophyletic clades were found that did not correspond exactly with...

Phylogenetic reassessment of Nigrospora: Ubiquitous endophytes, plant and human pathogens
Provedor de dados: Naturalis Digital Academic Repository
Autores: Wang, M.; Liu, F.; Crous, P.W.; Cai, L.
Species of Nigrospora commonly occur as plant pathogens, endophytes or saprobes, and have been shown to be extremely interesting for the discovery of novel metabolites. The familial placement, as well as phylogenetic relationships among Nigrospora species remain ambiguous. In this study, Nigrospora (= Khusia) is confirmed as a monophyletic genus belonging to Apiosporaceae (Xylariales), based on a phylogeny inferred from LSU sequence data. A multi-locus phylogeny based on ITS, TEF1-α and TUB2, in conjunction with morphological characters, host associations, and ecological data was employed for species delimitation in Nigrospora, as well as identification of 165 recently collected isolates from China, and three from Europe. In total 13 novelties are proposed...

The phylogenetic position of Rhopalostroma as inferred from a polythetic approach
Provedor de dados: Naturalis Digital Academic Repository
Autores: Stadler, M.; Fournier, J.; Gardt, S.; Peršoh, D.
The xylariaceous genus Rhopalostroma comprises a small conglomerate of stromatic, angiospermassociated pyrenomycetes, which have so far exclusively been reported from the palaeotropics, above all from tropical Africa and South Asia. Morphological and chemotaxonomic studies had suggested their close relationship to the genera Daldinia and Hypoxylon. However, those results were mainly based on herbarium specimens, and no molecular phylogenetic data were available on Rhopalostroma. During a foray in Côte d’Ivoire, fresh material of R. angolense was collected, cultured and studied by microscopic methods and by secondary metabolite profiling using high performance liquid chromatography coupled with diode array and mass spectrometric detection. In addition, ITS...

Persistent hamathecial threads in the Nectriaceae, Hypocreales: Thyronectria revisited and re-instated
Provedor de dados: Naturalis Digital Academic Repository
Autores: Jaklitsch, W.M.; Voglmayr, H.
Based on type studies and freshly collected material we here re-instate the genus Thyronectria (Nectriaceae, Hypocreales). Species of this genus were recently for the most part classiﬁed in the genera Pleonectria (Nectriaceae) or Mattirolia (Thyridiaceae), because Thyronectria and other genera had been identiﬁed as members of the Thyridiaceae due to the presence of paraphyses. Molecular phylogenies based on several markers (act, ITS, LSU rDNA, rpb1, rpb2, tef1, tub) revealed that the Nectriaceae contain members whose ascomata are characterised by long, more or less persistent, apical paraphyses. All of these belong to a single genus, Thyronectria, which thus has representatives with hyaline, rosy, green or even dark brown and sometimes distoseptate...

Toxicidade de filtrados de cultura de Alternaria euphorbiicola em folhas de Euphorbia heterophylla
Provedor de dados: Planta Daninha
Autores: Varejão,E.V.V; Demuner,A.J; Barbosa,L.C.A; Barreto,R.W; Vieira,B.S.
A espécie fúngica Alternaria euphorbiicola é agente causal de severas necroses de inflorescência, queimas de folhas e cancros da haste em Euphorbia heterophylla (leiteiro ou amendoim-bravo), importante planta daninha responsável por grandes prejuízos à agricultura brasileira. A aplicação de suspensões de esporos do fungo sobre populações da planta hospedeira resulta em rápida produção de necrose dos tecidos das plantas (24 a 48 horas após aplicação). Essas observações levaram à conjectura de que o fungo possa produzir fitotoxinas in vitro capazes de causar lesão às plantas. O objetivo deste trabalho foi investigar preliminarmente a produção in vitro de fitotoxinas por A. euphorbiicola sob diferentes condições de cultivo. Os resultados mostraram que a...

Abiotic effects on the cover and richness of corticolous lichens on Araucaria angustifolia trunks
Provedor de dados: Acta Botanica Brasilica
Autores: Nunes,Lucas; Burle,Giulia; Gumboski,Emerson Luiz; Dechoum,Michele.
ABSTRACT Lichens play a key role in natural ecosystems, as they can function as primary producers, recycle minerals and fix nitrogen. Despite their environmental importance, little is known about lichen ecology in Brazil, and especially about how abiotic factors may influence their spatial distribution. In this study, we aimed to verify how the cover and richness of corticolous lichens on Araucaria angustifolia trunks vary between two different habitats (Forest and Grassland). The photoquadrat sampling method was applied to A. angustifolia trunks. The Coral Point Count software with Excel extensions (CPCe) was used to analyze photographs for lichen cover and richness. Additionally, a redundancy analysis was conducted to estimate how five abiotic and two...

Autores: Rajamanikyam,Maheshwari; Vadlapudi,Varahalarao; amanchy,Ramars; Upadhyayula,Suryanarayana Murty.
ABSTRACT Fungal endophytes constitute a major part of the unexplored fungal diversity. Endophytic fungi (EF) are an important source for novel, potential and active metabolites. Plant-endophyte interaction and endophyte -endophyte interactions study provide insights into mutualism and metabolite production by fungi. Bioactive compounds produced by endophytes main function are helping the host plants to resist external biotic and abiotic stress, which benefit the host survival in return. These organisms mainly consist of members of the Ascomycota, Basidiomycota, Zygomycota and Oomycota. Recently, the genome sequencing technology has emerged as one of the most efficient tools that can provide whole information of a genome in a small period of time....
