文摘During a microfungi survey in the Province of Forlì-Cesena,Italy,a diatrypaceous taxon was collected on a dead branch of Quercus cerris(Fagaceae,Fagales).Phylogenetic analyses of combined ITS andβ-tubulin sequence data identified the taxon as Diatrypella macrospora.This represents a new host and geographical record for D.macrospora.This new collection is similar to the holotype,but differs in having shorter perithecial necks and smaller ascospores with marked curvature.In this account,a detailed description,colour photographs and phylogenetic analyses are provided to represent the new record of D.macrospora.

文摘Sexual morph of didymellaceous taxa are characterized by their ascomata with relatively thin peridium,cylindric-clavate to clavate,short-pedicellate or apedicellate asci,hyaline to brown,1-septate to muriform ascospores.Its asexual morphs are coelomycetous and comprising pycnidial or acervulus conidiomata,phialidic,hyaline conidiogenous cells and hyaline or pale brown,septate or aseptate conidia.The majority of these cosmopolitan species are plant associated fungi which can be pathogens on a wide range of hosts and some species are of particular relevance for quarantine measures.Recent studies have significantly improved the taxonomy and systematics of didymellaceous taxa based on molecular phylogenetics.In contrast to the accurate and detailed studies on the asexual morphs which are common obligate pathogens,information on their usually saprobic sexual morphs is still limited.Among these phenotypically diverse species,spore characteristics are quite unique as most have hyaline spores with 0-1 septum,while only Neomicrosphaeropsis and Didymellocamarosporium are reported as producing pigmented,muriform spores.These dematiaceous muriform spores are characteristic of a considerable number of species that may be quite divergent in other characters.During taxonomic investigations on the diversity of didymellaceous taxa,we have isolated species from Alhagi pseudalhagi,Coronilla emerus,Cytisus sp.,Elaeagnus angustifolia and Spartium junceum in Italy,Russia and Uzbekistan.A comprehensive phylogeny,based on four loci(ITS,LSU,rpb2 and tub2)is used to infer species relationships.Comprehensive morphological descriptions and in-depth phylogenetic investigations of five new species viz.Ascochyta coronillae-emeri,Microsphaeropsis spartii-juncei,Neomicrosphaeropsis alhagi-pseudalhagi,N.cytisicola and N.elaeagni are presented.

文摘Demarcation of family,genus and species boundaries in the Diaporthales has been tentative due to uninformative illus-trations and descriptions,overlapping morphological characteristics,misplacement or poor condition of type specimens and shortage of molecular data from ex-type cultures.In this study,we obtained the type specimens or other authentic specimens of diaporthalean taxa from worldwide fungaria.We examined,described and illustrated them.This study is based on morphological characters from type or authentic specimens,details from protologue and original illustrations and molecular data obtained from GenBank.Combined analyses of nrITS,nrLSU,RPB2 and TEF1-a sequence data were used to construct the molecular phylogeny.Additionally,we provided separate phylogenetic trees for families when necessary to show the generic distribution within these families based on suitable gene markers.Based on morphology and phylogeny,we treat 17 genera previously assigned to Diaporthales genera incertae sedis within several families.For some genera we have designated new generic types as they are lacking type species or type species have affiliations with other families.We exclude Anisomycopsis from Diaporthales and place it in Xylariomycetidae genera incertae sedis.Tirisporellaceae,which was previously placed in Tirisporellales is placed in Diaporthales based on phylogeny and morphology.A new combi-nation,Dendrostoma leiphaemia propose for Amphiporthe leiphaemia(Fr.)Butin.Based on the morphological characters and molecular data we accept 27 families and 138 genera within Diaporthales,24 genera in Diaporthales genera incertae sedis and one genus in Xylariomycetidae genera incertae sedis.We provide notes for genera in Diaporthales genera incertae sedis,and excluded and doubtful genera are listed with notes on their taxonomy and phylogeny.

文摘Anthostomella has long been regarded as a large,but polyphyletic genus in the family Xylariaceae,but species in this group generally lack phylogenetic data.In this study,14 anthostomella-like taxa collected from Italy,were studied using both morphology and molecular data.Single ascospore isolates were obtained and the asexual morphs of five taxa established.The phylogenetic relationships of the xylariaceous taxa were inferred using combined ITS,RPB2,βtubulin and LSU gene regions.We introduce new sequence data for 24 with included the 14 new anthostomella-like taxa.The subfamilies Hypoxyloideae and Xylarioideae within Xylariaceae were recognized as the two major clades with high bootstrap support.Within the two clades 21 subclades were resolved and the anthostomella-like taxa clustered in five of these subclades indicating that the genus is polyphyletic.Anthostomella sensu stricto comprised A.forlicesenica,A.formosa,A.helicofissa,A.rubicola and A.obesa.The A.formosa and A.rubicola collections morphologically closely resemble the type specimens and therefore we designate reference specimens.Three new species Anthostomella helicofissa,A.forlicesenica and A.obesa are also introduced.Four distinct lineages of anthostomella-like taxa correspondent to four new genera,Anthocanalis,Brunneiperidium,Lunatiannulus and Pyriformiascoma,which are also introduced,while one clustered in Astrocystis and is introduced as a new species.Keys to the new anthostomella-like genera and species examined in this study are provided.

文摘Phaeosphaeriaceae is a large and important family in the order Pleosporales which includes economically important plant pathogens.Species may also be endophytes or saprobes on plant hosts,especially on monocotyledons(e.g.,Cannaceae,Cyperaceae,Juncaceae,Poaceae);some species have also been reported on dicotyledons.The family previously accommodated 35 sexual and asexual genera and comprised more than 300 species with a range of morphological characters.The morphological characters of taxa in this family are often ambiguous and can be confused with other taxa in Leptosphaeriaceae and Montagnulaceae.Fourteen specimens of the type genera of Phaeosphaeriaceae were loaned from herbaria worldwide and were re-examined and illustrated.Fresh collections were obtained from Italy and Thailand,characterized,examined,isolated into pure culture and used to obtain molecular data.The asexual state was induced where possible on sterile bamboo pieces placed on water agar.Multigene phylogenetic analyses of ITS,LSU,SSU,RPB2 and TEF1 sequence datasets were carried out using maximum likelihood,maximum parsimony and Bayesian analysis.Molecular analyses shows that 21 genera(Amarenomyces,Ampelomyces,Chaetosphaeronema,Dematiopleospora,Entodesmium,Loratospora,Neosetophoma,Neostagonospora,Nodulosphaeria,Ophiobolus,Ophiosphaerella,Paraphoma,Parastagonospora,Phaeosphaeria,Phaeosphaeriopsis,Sclerostagonospora,Setomelanomma,Setophoma,Vrystaatia,Wojnowicia and Xenoseptoria)belong in Phaeosphaeriaceae,while seven genera(Amarenographium,Bricookea,Dothideopsella,Eudarluca,Phaeostagonospora,Scolecosporiella and Tiarospora)are included based on morphological data.Amarenomyces is reinstated and Nodulosphaeria is confirmed in Phaeosphaeriaceae.Eudarluca is distinguished from Sphaerellopsis based on its morphological characters and is typical of Phaeosphaeriaceae.ITS gene phylogenetic analys is indicates that Sphaerellopsis belongs to Leptosphaeriaceae.Ophiobolus species form a clade within Phaeosphaeriaceae while Ophiosphaerella is shown to be polyphyletic.Phaeosphaeria sensu stricto is redefined.Two new species of Phaeosphaeria and one of Phaeosphaeriopsis are introduced while the asexual states of Phaeosphaeria chiangraina and Phaeosphaeriopsis dracaenicola are reported.Scolicosporium minkeviciusii forms a sister clade with Neostagonospora and Parastagonospora in Phaeosphaeriaceae.However,Scolicosporium minkeviciusii is not the type species.Thus,the placement of Scolicosporium sensu stricto in Phaeosphaeriaceae is questionable.Phylogenetic analysis of combined ITS and LSU genes,confirm the placement of Septoriella oudemansii in Phaeosphaeriaceae.However,it is not represented by the generic type,thus the placement of Septoriella is questionable.Setophaeosphaeria is excluded from Phaeosphariaceae as the type species,Sp.hemerocallidis forms a clade at the base of Cucurbitariaceae.Wilmia clusters in Didymosphaeriaceae and is synonymized under Letendraea.Barria,Chaetoplea,Hadrospora,Lautitia,Metameris,Mixtura and Pleoseptum are excluded from Phaeosphaeriaceae based on their morphological characters.The asexual genera Mycopappus and Xenostigmina are excluded from this family based on the phylogenetic evidence;these genera form a clade close to Melanommataceae.

文摘The ascomycetous families,Didymosphaeriaceae and Montagnulaceae,have been treated in Pleosporales,Dothideomycetes,and both include saprobes,endophytes and pathogens associated with a wide variety of substrates worldwide.Didymosphaeriaceae was characterized by 1-septate ascospores and trabeculate pseudoparaphyses,mainly anastomosing above the asci,while species in Montagnulaceae had 1 to multi-septate ascospores and generally cellular pseudoparaphyses.In recent treatments,Bimuria,Didymocrea,Kalmusia,Karstenula,Montagnula,Paraphaeosphaeria,Paraconiothyrium and Letendraea were placed in Montagnulaceae,while only Didymosphaeria has been placed in Didymosphaeriaceae.New morphological and molecular data from recent collections have become available and thus the understanding of the families can be improved.Based on analyses of concatenated internal transcribed spacer(ITS)with LSU,SSU andβ-tubulin gene sequences,the taxonomy of the genera classified in these families are reassessed.Our phylogenetic analyses conclude that,the recently introduced Didymosphaeria rubi-ulmifolii with Paraconiothyrium brasi liense species complex,Alloconiothyrium,Bimuria,Deniquelata,Didymocrea,Kalmusia,Karstenula,Letendraea,Montagnula,Neokalmusia,Paraconiothyrium,Paraphaeosphaeria,Phaeodothis and Tremateia,forms a robust clade named here Didymosphaeriaceae.We therefore synonymize Montagnulaceae under Didymosphaeriaceae which is the oldest name and has priority and provide a update account of the family.Didymosphaeria is represented by Didymosphaeria rubi-ulmifolii.A new genus,Neokalmusia,is introduced in the family to accommodate the bambusi colous taxa Kalmusia brevispora and K.scabrispora.This introduction is based on molecular data coupled with morphology.One new species,Paraconiothyrium magnoliae and the sexual morph of Paraconiothyrium fuckelii,is also introduced.Julella and Barria are assigned to the family based on morphological similarity with Didymosphaeriaceae.Wilmia(previously referred to the Phaeosphaeriaceae)is synonymized under Letendraea(Didymosphaeriaceae).Furthermore,a new species,Letendraea cordylinicola,is introduced and placed in Didymosphaeriaceae based on phylogeny and morphology.The paraphyletic nature of Paraconiothyrium is partially resolved,but further sampling with fresh collections and molecular data of species in this genus are needed to obtain a natural classification.

文摘Fungi that are barely lichenized or non-lichenized and closely related to lichenized taxa,the so-called borderline fungi,are an important element in reconstructing the evolutionary history of lichenized lineages.Arthoniaceae is a prime example including non-lichenized,saprotrophic lineages which potentially were precursors to lichenized taxa.In this study,we focused on saprotrophic species of Arthonia sensu lato,including new sequence data for Arthonia pinastri.We obtained fresh material of this taxon from a living branch of Fraxinus ornus in Italy to assess its taxonomic status and to elucidate its phylogenetic relationships within Arthonia.Thin sections of the thallus and ascomata of A.pinastri confirmed the absence of a photobiont.Maximum likelihood and Bayesian analyses of combined mtSSU,nuLSU and RPB2 sequence data placed the species close to A.dispersa(barely lichenized or non-lichenized)and A.punctiformis(non-lichenized)in a clade closely related to Arthonia sensu stricto,and the A.pinastri clade is here resurrected under the name Naevia.Ancestral character state analysis within a broader context of Arthoniales does not support the saprotrophic lifestyle to be a plesiomorphic feature,but suggests loss of lichenization in Naevia,as well as loss and possible regain in a second clade containing saprotrophic species and including taxa resembling Mycoporum,underlining the evolutionary plasticity of Arthoniales.These two clades constitute model taxa to further investigate the evolution of alternative biological lifestyles within the context of chiefly lichenized taxa.
文摘The family Melanommataceae is widespread in temperate and subtropical regions and species invariably occur on twigs or bark of various woody plants in terrestrial,marine or freshwater habitats.In this paper,the type species of 26 genera of the family are re-described and illustrated.A multi-gene phylogeny based on maximum likelihood and Bayesian analyses of LSU,SSU,RPB2 and EF-1αsequence data of species of Melanommataceae is provided.The new genera,Muriformistrickeria,Pseudostrickeria and Thysanolaenae are introduced.Anomalemma is synonymized under Exosporiella.Acrocordiopsis,Astrosphaeriella,Beverwykella,Caryosporella,Sporidesmiella and Pseudotrichia are excluded from Melanommataceae based on molecular phylogenetic analyses.Presently,20 genera are accepted in Melanommataceae.Based on the phylogenetic data,five new species,Byssosphaeria siamensis,Herpotrichia vaginatispora,Pseudostrickeria muriformis,Pseudostrickeria ononidis and Muriformistrickeria rubi,are introduced.

文摘Xylariomycetidae(Ascomycota)is a highly diversified group with variable stromatic characters.Our research focused on inconspicuous stromatic xylarialean taxa from China,Italy,Russia,Thailand and the United Kingdom.Detailed morpho-logical descriptions,illustrations and combined ITS-LSU-rpb2-tub2-tef1 phylogenies revealed 39 taxa from our collections belonging to Amphisphaeriales and Xylariales.A new family(Appendicosporaceae),five new genera(Magnostiolata,Mela-nostictus,Neoamphisphaeria,Nigropunctata and Paravamsapriya),27 new species(Acrocordiella photiniicola,Allocryp-tovalsa sichuanensis,Amphisphaeria parvispora,Anthostomella lamiacearum,Apiospora guiyangensis,A.sichuanensis,Biscogniauxia magna,Eutypa camelliae,Helicogermslita clypeata,Hypocopra zeae,Magnostiolata mucida,Melanostictus longiostiolatus,M.thailandicus,Nemania longipedicellata,N.delonicis,N.paraphysata,N.thailandensis,Neoamphispha-eria hyalinospora,Neoanthostomella bambusicola,Nigropunctata bambusicola,N.nigrocircularis,N.thailandica,Occul-titheca rosae,Paravamsapriya ostiolata,Peroneutypa leucaenae,Seiridium italicum and Vamsapriya mucosa)and seven new host/geographical records are introduced and reported.Divergence time estimates indicate that Delonicicolales diverged from Amphisphaeriales+Xylariales at 161(123-197)MYA.Amphisphaeriales and Xylariales diverged 154(117-190)MYA with a crown age of 127(92-165)MYA and 147(111-184)MYA,respectively.Appendicosporaceae(Amphisphaeriales)has a stem age of 89(65-117)MYA.Ancestral character state reconstruction indicates that astromatic,clypeate ascomata with aseptate,hyaline ascospores that lack germ slits may probably be ancestral Xylariomycetidae having plant-fungal endo-phytic associations.The Amphisphaeriales remained mostly astromatic with common septate,hyaline ascospores.Stromatic variations may have developed mostly during the Cretaceous period.Brown ascospores are common in Xylariales,but they first appeared in Amphisphaeriaceae,Melogrammataceae and Sporocadaceae during the early Cretaceous.The ascospore germ slits appeared only in Xylariales during the Cretaceous after the divergence of Lopadostomataceae.Hyaline,filiform and apiospores may have appeared as separate lineages,providing the basis for Xylariaceae,which may have diverged inde-pendently.The future classification of polyphyletic xylarialean taxa will not be based on stromatic variations,but the type of ring,the colour of the ascospores,and the presence or absence or the type of germ slit.

文摘Ophiobolus is a large genus of Phaeosphaeriaceae comprising more than 350 possible species,most of which are saprobes on herbaceous plants in Europe and North America.Ophiobolus species are polyphyletic and the type of Ophiobolus is not represented in GenBank.Therefore,an increased taxon sampling of ophiobolus-like taxa and epitypification of the type species,O.disseminans is reported.Multigene phylogenetic analyses of combined LSU,SSU,TEF1-a and ITS sequence data position O.disseminans in a sister clade with O.ponticus and several Entodesmium species in Phaeosphaeriaceae with high support.Therefore,Entodesmium is synonymized under Ophiobolus.Premilcurensis with it type species,P.senecionis also clusters within the Ophiobolus clade and is synonymized under Ophiobolus.Ophiobolus rossicus sp.nov.is introduced and a reference specimen is designated for O.ponticus.Other ophiobolus-like taxa(Ophiobolus sensu lato)can be distinguished as three main groups,which are introduced as new genera.Ophiobolopsis is introduced to accommodate the new species,Ophiobolopsis italica.The new genus Paraophiobolus is introduced to accommodate P.arundinis sp.nov.and P.plantaginis comb.nov.This genus is characterized by hyaline to pale yellowish ascospores,some green-yellowish at maturity,with a swollen cell,terminal appendages and ascospores not separating into part spores.Pseudoophiobolus gen.nov.is introduced to accommodate six new species and two new combinations,viz.Ps.achilleae,Ps.erythrosporus,Ps.galii,Ps.italicus,Ps.mathieui,Ps.rosae,Ps.subhyalinisporus and Ps.urticicola.Pseudoophiobolus is characterized by subhyaline to pale yellowish or yellowish ascospores,with a swollen cell,lack of terminal appendages and ascospores that do not separate into part spores and is related to Nodulosphaeria.An updated tree for Phaeosphaeriaceae based on multigene analysis is also provided.

文摘The global diversity of fungi has been estimated using several different approaches.There is somewhere between 2–11 million estimated species,but the number of formally described taxa is around 150,000,a tiny fraction of the total.In this paper,we examine 12 ascomycete genera as case studies to establish trends in fungal species descriptions,and introduce new species in each genus.To highlight the importance of traditional morpho-molecular methods in publishing new species,we introduce novel taxa in 12 genera that are considered to have low species discovery.We discuss whether the species are likely to be rare or due to a lack of extensive sampling and classification.The genera are Apiospora,Bambusicola,Beltrania,Capronia,Distoseptispora,Endocalyx,Neocatenulostroma,Neodeightonia,Paraconiothyrium,Peroneutypa,Phaeoacremonium and Vanakripa.We discuss host-specificity in selected genera and compare the number of species epithets in each genus with the number of ITS(barcode)sequences deposited in GenBank and UNITE.We furthermore discuss the relationship between the divergence times of these genera with those of their hosts.We hypothesize whether there might be more species in these genera and discuss hosts and habitats that should be investigated for novel species discovery.

文摘The family Pleosporaceae includes numerous saprobic,opportunistic human,and plant pathogenic taxa.The classification of genera and species Pleosporaceae has been a major challenge due to the lack of a clear understanding of the importance of the morphological characters used to distinguish taxa as well as the lack of reference strains.Recent treatments concluded that Pleospora and some other genera in Pleosporaceae are likely polyphyletic.In order to establish the evolutionary relationships and to resolve the polyphyletic nature of Pleospora and allied genera,we sequenced the 18S nrDNA,28S nrDNA,ITS,GAPDH,RPB2 and TEF1-alpha gene regions of Pleosporaceae species and phylogenetically analysed this data.Multigene phylogenies strongly support the monophyletic nature of Pleosporaceae among the other families in Pleosporales,and the acceptance of the genera Alternaria,Bipolaris,Clathrospora,Comoclathris,Curvularia,Dactuliophora,Decorospora,Diademosa,Exserohilum,Extrawettsteinina,Gibbago,Neocamarosporium,Paradendryphiella,Platysporoides,Pleospora,Porocercospora,Pseudoyuconia and Pyrenophora.Austropleospora,Dendryphion,Edenia and Macrospora are excluded from the family based on morphology coupled with molecular data.Two novel species,Alternaria murispora in this paper and Comoclathris sedi are introduced.The sexual morph of Alternaria alternata is re-described and illustrated using modern concepts from fresh collections.The paraphyletic nature of Pleospora is resolved based on the available morpho-molecular data,but further sampling with fresh collections,reference or ex-type strains and molecular data are needed to obtain a natural classification of genera and the family.
