Sexual reproduction is the basic way to form high genetic diversity and it is beneficial in evolution and speciation of fungi.The global diversity of teleomorphic species in Ascomycota has not been estimated.This paper estimates the species number for sexual ascomycetes based on five different estimation approaches,viz.by numbers of described fungi,by fungus:substrate ratio,by ecological distribution,by meta-DNA barcoding or culture-independent studies and by previous estimates of species in Ascomycota.The assumptions were made with the currently most accepted,“2.2–3.8 million”species estimate and results of previous studies concluding that 90%of the described ascomycetes reproduce sexually.The Catalogue of Life,Species Fungorum and published research were used for data procurement.The average value of teleomorphic species in Ascomycota from all methods is 1.86 million,ranging from 1.37 to 2.56 million.However,only around 83,000 teleomorphic species have been described in Ascomycota and deposited in data repositories.The ratio between described teleomorphic ascomycetes to predicted teleomorphic ascomycetes is 1:22.Therefore,where are the undiscovered teleomorphic ascomycetes?The undescribed species are no doubt to be found in biodiversity hot spots,poorly-studied areas and species complexes.Other poorly studied niches include extremophiles,lichenicolous fungi,human pathogens,marine fungi,and fungicolous fungi.Undescribed species are present in unexamined collections in specimen repositories or incompletely described earlier spe-cies.Nomenclatural issues,such as the use of separate names for teleomorph and anamorphs,synonyms,conspecific names,illegitimate and invalid names also affect the number of described species.Interspecies introgression results in new species,while species numbers are reduced by extinctions.

Taxonomic placement of genera have been changing rapidly as taxonomists widely use DNA sequence data in phylogenetic and evolutionary studies. It is essential to update existing databases/outlines based on recent studies, since thesesources are widely used as a foundation for other research. In this outline, we merge both asexual and sexual genera intoone outline. The phylum Ascomycota comprises of three subphyla viz. Pezizomycotina (including 13 classes, 124 ordersand 507 families), Saccharomycotina (including one class, one order and 13 families) and Taphrinomycotina (five classes,five orders and six families). Approximately, 6600 genera have been listed under different taxonomic ranks includingauxiliary (intermediate) taxonomic ranks.

Bamboos not only provide socio-economic benefits to communities within the region,but also provide ecosystem services such as soil-water conservation,stabilization of sandy soils and restoration of soil nutrients.Bambusicolous ascomycetes refer to ascomycetous fungi living on any substrate of bamboo.As the largest group of fungi on bamboo,they play a significant ecological value in species composition and the structure of the fungal community,circulation of materials and energy flow of nutritional elements.In an effort to document the bambusicolous Ascomycota found in China,we assessed all major sources of academic literature,journal papers,and the USDA database(https://nt.***.gov/fungaldatabases/fungushost/fungushost.cfm)for reports of these fungi from China.As a result,we produced a systematic and comprehensive checklist of bambusicolous Ascomycota in China.Current names of fungi,bamboo host name,bamboo substrate,details of collected localities,references and latest classification for every bambusicolous ascomycete in China are also provided.In addition,we focused on the species richness of bambusicolous Ascomycota in China with an emphasis on southwest China.

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.

Astrosphaeriella sensu lato is a common genus occurring on bamboo,palms and stout grasses.Species of Astrosphaeriella have been collected from various countries in tropical,subtropical or temperate regions.In Asia,species have been collected in Brunei,China,Indonesia,Japan,Philippines and Vietnam.There have been several morphological studies on Astrosphaeriella,but molecular work and phylogenetic analyses are generally lacking.Taxa included in Astrosphaeriella were characterized in three main groups 1)typical Astrosphaeriella species(sensu stricto)having carbonaceous,erumpent,conical ascostromata 2)atypical Astrosphaeriella species(sensu lato)having immersed,coriaceous ascostromata with short to long papilla and 3)lophiostoma-like species having immersed ascostromata with slit-like openings.Some of the latter Astrosphaeriella species,having slit-like openings,have been transferred to Fissuroma and rimora in Aigialaceae.In this study five type specimens of Astrosphaeriella were loaned from herbaria worldwide and re-examined and are re-described and illustrated.Collections of Astrosphaeriella were also made in Thailand and morphologically examined.Pure cultures were obtained from single spores and used in molecular studies.The asexual morph was induced on sterile bamboo pieces placed on water agar.Phylogenetic analyses of combined LSU,SSU and TEF1 sequence data of astrosphaeriella-like species using Bayesian,Maximum parsimony(MP)and randomized Accelerated Maximum Likelihood(rAxML)analyses were carried out.Phylogenetic analyses show that species of Astrosphaeriella can be distinguished in at least three families.Species of Astrosphaeriella sensu stricto with erumpent,carbonaceous ascostromata,form a strongly supported clade with Pteridiospora species and a new family,Astrosphaeriellaceae,is introduced to accommodate these taxa.The genera are revised and Astrosphaeriella bambusae,A.neofusispora,A.neostellata,A.thailandica,A.thysanolaenae and Pteridiospora chiangraiensis are introduced as new species.Astrosphaeriella

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.***.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.***.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.***.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.

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 polyphyle

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
