Citrofortunella microcarpa locally known as“kalamansi”belongs to the family Rutaceae is one of the most important marketable fruit crops grown in the Philippines.Aside from being a fruit crop,the plant also houses various endophytic microorganisms which exhibit various symbiotic relationships.Thus,this study isolated fungal endophytes from C.microcarpa stem and leaves and were identified culturally and morphologically.The identities of the fungal species were confirmed using ITS1 and ITS4 sequences.The identified fungal endophytes were tested for their ability to produce fungal enzymes such as amylase,cellulase,laccase and protease.Totally 11 fungal endophytes were isolated from stem and leaves of C.microcarpa namely,Colletotrichum fructicola,Colletorichum gloeosporioides,Colletotrichum siamense,Fusarium oxysporum,Lasiodiplodia theobromae,Nigrospora oryzae,Nigrospora rubi,Nodulisporium indicum,Phomopsis azadirachtae,Phyllosticta capitalensis,and an unidentified species under the Order Pleosporales.All the identified endophytic fungal species showed production of amylase.For the cellulose assay,four species namely L.theobromae,N.oryzae,C.gloeosporioides,and the unidentified species had potential for cellulose degradation.Fusarium oxysporum and P.azadirachtae were found to be producers of laccase.Meanwhile,only the unidentified species showed extracellular protease activity.

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

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 placement of the dothideomycetous family Teichosporaceae has been controversial.Recent phylogenetic investigations have used a taxonomic lumping approach with the Floricolaceae and its genera have been synonymized under the earlier fam-ily name,Teichosporaceae.Intergeneric relationships were therefore obscure and proper generic delimitation was needed in upcoming studies.We here taxonomically revised the family Teichosporaceae based on both morphological and phylogenetic evidence.Teichosporaceae species have immersed or semi-immersed,erumpent to superficial,ostiolate ascomata,cellular or trabeculate pseudoparaphyses,cylindrical to oblong or sub-clavate asci and ellipsoid to oblong or fusiform,cylindric-fusiform or oblong to elliptical,ovoid to clavate,symmetric or asymmetric,initially hyaline or pale brown to dark brown or yellowish brown,1-3-septate or muriform ascospores.Asexual morphs are coelomycetous.Type or representative speci-mens of Teichosporaceae were loaned and fresh specimens were collected from China and Thailand.Maximum likelihood and Bayesian analyses of a combined ITS,LSU,SSU,tef1-αand rpb2 dataset were performed to clarify the phylogenetic affinities of taxa and examine monophyly of newly proposed genera.One new species(Floricola festucae),one new host record(Ramusculicola thailandica)and four new combinations(Aurantiascoma nephelii,A.quercus,Magnibotryascoma acaciae,M.melanommoides)are introduced.The broad genus concept of Teichospora is dismissed based on morphological dissimilarities and the monophyletic status of the proposed genera.We accept Asymmetrispora,Aurantiascoma,Floricola,Magnibotryascoma,Misturatosphaeria,Pseudoaurantiascoma,Pseudomisturatosphaeria,Ramusculicola and Teichospora as distinct genera in the Teichosporaceae.All recognized genera are phenotypically characterized and phylogenetically well-supported.The phylogenetic placements of three genera(Chaetomastia,Loculohypoxylon and Sinodidymella),which do not have molecular data cannot be conclusively clarified at present,but

The current classification system for the recognition of taxonomic ranks among fungi,especially at highranking level,is subjective.With the development of molecular approaches and the availability of fossil calibration data,the use of divergence times as a universally standardized criterion for ranking taxa has now become possible.We can therefore date the origin of Ascomycota lineages by using molecular clock methods and establish the divergence times for the orders and families of Dothideomycetes.We chose Dothideomycetes,the largest class of the phylum Ascomycota,which contains 32 orders,to establish ages at which points orders have split;and Pleosporales,the largest order of Dothideomycetes with 55 families,to establish family divergence times.We have assembled a multi-gene data set(LSU,SSU,TEF1 and RPB2)from 391 taxa representing most family groups of Dothideomycetes and utilized fossil calibration points solely from within the ascomycetes and a Bayesian approach to establish divergence times of Dothideomycetes lineages.Two separated datasets were analysed:(i)272 taxa representing 32 orders of Dothideomycetes were included for the order level analysis,and(ii)191 taxa representing 55 families of Pleosporales were included for the family level analysis.Our results indicate that divergence times(crown age)for most orders(20 out of 32,or 63%)are between 100 and 220 Mya,while divergence times for most families(39 out of 55,or 71%)are between 20 and 100 Mya.We believe that divergence times can provide additional evidence to support establishment of higher level taxa,such as families,orders and classes.Taking advantage of this added approach,we can strive towards establishing a standardized taxonomic system both within and outside Fungi.In this study we found that molecular dating coupled with phylogenetic inferences provides no support for the taxonomic status of two currently recognized orders,namely Bezerromycetales and Wiesneriomycetales and these are treated as synonyms of Tubeufiales while Asterotexiales is tr
