Colletotrichum is one of the most important plant pathogenic genera that is responsible for numerous diseases which can have a profound impact on the agricultural sector.Species delineation is difficult due to a lack of distinctive phenotypic vari-ation.Therefore,in this study three different genomic approaches based on phylogenetic,evolutionary and coalescent-based methods are applied to establish robust species boundaries.The reliability of five different DNA barcodes was also assessed to provide further insights into species delineation.The ITS region can resolve the placement of taxa up to the species complex level.The GAPDH and TUB2 markers are determined to be the most informative for most complexes.However,no single marker could discriminate between species in all complexes,therefore different molecular approaches based on multi-locus datasets are recommended.This is the first study to provide an estimated divergence time for all species complexes in Colle-totrichum.The estimated divergence time for species complexes ranged between 4.8 to 32.2 MYA.Based on the high level of congruent results obtained from the different molecular approaches,a new species complex,the Colletotrichum agaves complex is introduced.This complex consists of five taxa which are characterised by the presence of straight or slightly curved conidia with obtuse apices.This study shows that coalescent approaches and multi-locus phylogeny are crucial to establish species boundaries in Colletotrichum.The taxonomic placement of three singleton taxa Colletotrichum axonopodi,C.cariniferi and C.parallelophorum is revised.We accept 248 species and provide recommendations regarding species boundaries in the graminicola-caudatum complex.

Bipolaris species are important plant pathogens with a worldwide distribution in tropical and temperate environments.Species recognition in Bipolaris has been problematic due to a lack of molecular data from ex-type cultures,the use of few gene regions for species resolution and overlapping morphological characters.In this study,we evaluate the efficiency of different DNA barcodes in species delimitation in Bipolaris by phylogenetic analyses,Automatic Barcode Gap Discovery and Objective Clustering.GAPDH is determined to be the best single marker for the genus.These approaches are used to clarify the taxonomic placement of all sequences currently named as Bipolaris in GenBank based on ITS and GAPDH gene sequence data.In checking various publications,we found that the majority of new host records of fungal species published in the Plant Disease journal from 2010 to 2019 were based on BLAST searches of the ITS sequences and up to 82%of those records could be erroneous.Therefore,relying on BLAST searches from GenBank to name species is not recommended.Editorial boards of journals and reviewers of new record papers should be aware of this problem.In naming Bipolaris species,whether new or known,it is recommended to perform phylogenetic analyses based on GAPDH using the correct taxon sampling for accurate results and the species relationship should have reliable statistical support.At least two new species are represented by molecular data in GenBank and we provide an updated taxonomic revision of Bipolaris.We accept 45 species in Bipolaris and notes are provided for all the species including hosts and geographic distribution.

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.

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.

Fungi play vital roles in ecosystems as endophytes,pathogens and saprobes.The current estimate of fungal diversity is highly uncertain,ranging from 1.5 to 12 million,but only around 150,000 species have been named and classified to date.Since the introduction of DNA based methods for species identification,the number of newly described taxa has increased from approximately 1000 to around 2000 yearly.This demonstrates the importance of DNA based methods to identify and distin-guish species,especially cryptic species.Many novel species from recent studies have been found in historically understudied regions and habitats,but these still represent only a small percentage of the estimated species.In this paper,we examine 16 genera from the top 40 most speciose genera as listed in Species Fungorum as case studies to examine the diversity of taxa in each genus.The genera treated herein are Cercospora,Diaporthe,Meliola,Passalora,Phyllachora,Phyllosticta,Pseudocer-cospora,Ramularia(ascomycetes)and Cortinarius,Entoloma,Inocybe,Marasmius,Psathyrella,Puccinia,Russula,Uromyces(basidiomycetes).We critically evaluate the number of species in these genera and correlate these numbers with the number of entries in GenBank.We introduce 18 new species Apiospora multiloculata,Candolleomyces thailandensis,Cortinarius acutoproximus,Cortinarius melleoalbus,Cortinarius pacificus,Cortinarius parvoacetosus,Diaporthe guizhouensis,Entoloma pseudosubcorvinum,Inocybe meirensongia,Marasmius albulus,Marasmius obscuroaurantiacus,Meliola camporesii,Phyl-lachora siamensis,Phyllosticta doitungensis,Picipes yuxiensis,Pseudocercospora vignae,Puccinia maureanui and Russula inornata.We also introduce a new record of Candolleomyces cladii-marisci and Inocybe iringolkavensis.We discuss the genera Colletotrichum and Pleurotus that are speciose,but do not occur in the top 40.We hypothesize whether there might be more species in these genera and discuss why these genera have some of the largest number of species.

Fungi have evolved diverse strategies to acquire nutrients as endophytes,saprobes,symbionts,or pathogens.Appressoria have been intensively studied due to their importance in attaching and breaching the host surface.These specialized infection structures have evolved into various morpho-types:proto-appressoria,hyaline appressoria,melanized(dark)appressoria,and compound appressoria.In this review,we discuss the differences in the formation,differentiation,and function of appres-soria among fungi with diverse life strategies.Using DNA sequence information,LSU,5.8S,SSU and rpb2 gene fragments,we reconstructed the ancestral states for appressorial types in the main phyla of fungi and fungus-like organisms and found that the hyaline appressoria was the most ancestral form.Our analysis estimated proto-appressoria diversification during the Mesozoic period(92-239 million years ago),however,its origin remains inconclusive.Our data suggest that these hyaline appressoria diversified into melanized or compound appressoria,with evidence of adaptive radiation.

Leptosphaeriaceae is a family in the order Pleosporales comprising economically important plant pathogens.Species may also be endophytes or saprobes on various host plants.In recent classifications Alternariaster,Leptosphaeria,Neophaeosphaeria,Paraleptosphaeria,Heterospora,Subplenodomus and Plenodomus were included in the family.The taxonomy of genera and species in Leptosphaeriaceae has been problematic due to the lack of understanding of the importance of morphological characters used to distinguish taxa,as well as the lack of reference strains.In order to establish evolutionary relationships and to provide a backbone tree for Leptosphaeria and allied genera,we sequenced the 18S nrDNA,28S nrDNA,ITS,RPB2,TEF and ACT gene regions of Leptosphaeriaceae species and analysed this data.Multi-locus phylogenies together with morphology robustly support the monophyletic nature of Leptosphaeriaceae among the other families in Pleosporales,and the inclusion of the genera Alternariaster,Heterospora,Leptosphaeria,Paraleptosphaeria,Sphaerellopsis,Subplenodomus,Plenodomus and three novel genera Alloleptosphaeria,Neoleptosphaeria and Pseudoleptosphaeria.Five new species,Alternariaster centaureae-diffusae,Leptosphaeria cichorium,Paraleptosphaeria rubi,Plenodomus guttulatus and P.salviae are introduced.An account of sexual morph of Alternariaster centaureae-diffusae is provided,and the sexual morph of Leptosphaeria doliolum is re-described and illustrated using modern concepts from fresh collections.A novel family Neophaeosphaeriaceae is established to accommodate the genus Neophaeosphaeria and its species.
