An economical space is a dynamic model for any scope of certain economy and market . ln an economical space, any point represents some economical area or entity and is assigned an variable economic condition Any subspace is assigned an variable economic evaluation. FEEC controller operates oz. economic evaluation and the public parts in economic condition. Any adjustment done by FEEC controller asks the point itself to improve other members to meet the requirements. ln this paper, the template for economic condition and economic evaluation is defined , and then the generic type of economical space and FEE. controller is also given. 展开更多

The type specimens of Auerswaldia,Auerswaldiella,Barriopsis,Botryosphaeria,Leptoguignardia,Melanops,Neodeightonia,Phaeobotryon,Phaeobotryosphaeria,Phyllachorella,Pyrenostigme,Saccharata,Sivanesania,Spencermartinsia and Vestergrenia were examined and fresh specimens of Botryosphaeriales were collected from Thailand.This material is used to provide a systematic treatment of Botryosphaeriales based on morphology and phylogeny.Two new genera,Botryobambusa and Cophinforma are introduced and comparedwith existing genera.Four species newto science,Auerswaldia dothiorella,A.lignicola,Botryosphaeria fusispora and Phaeobotryosphaeria eucalypti,are also described and justified.We accept 29 genera in Botryosphaeriales,with Macrovalsaria being newly placed.In the phylogenetic tree,the 114 strains of Botyrosphaeriales included in the analysis cluster into two major clades with 80%,96%and 1.00(MP,ML and BY)support,with Clade A containing the family type of Botryosphaeriaceae,and Clade B containing Phyllosticta,Saccharata and Melanops species.This group may represent Phyllostictaceae.In Clade A the taxa analyzed cluster in eight sub-clades(Clades A1-8).Clade A1 comprises three distinct subclusters corresponding to the genera Diplodia(Diplodia Clade),Neodeightonia(Neodeightonia Clade)and Lasiodiplodia(Lasiodiplodia Clade).Clade A2 clusters into three groups representing Phaeobotryosphaeria(100%),Phaeobotryon(100%)and Barriopsis(94%).Clade A3 incorporates 17 strains that cluster into three well-supported genera(Dothiorella(86%),Spencermartinsia(100%)and Auerswaldia(63%);the position of Macrophomina is not stable.Clade A4 is a single lineage(100%)representing the new genus Botryobambusa.Clade A5 is a wellsupported subclade incorporating Neofussicoccum.Clade A6 represents the type species of Botryosphaeria,three other Botryosphaeria species and two other genera,Neoscytalidium and Cophinforma gen.nov.Clade A7 comprises two Pseudofusicoccum species and Clade A8 has two Aplosporella species.These sub-clades may eventually require separate families but this requires analysis of a much larger dataset.Our data advances the understanding of Botryosphaeriales,there is,however,still much research to be carried out with resolution of families and genera,linkage of sexual and asexual morphs and differentiation of cryptic species. 展开更多

The genus Diaporthe comprises pathogenic,endophytic and saprobic species with both temperate and tropical distributions.Cryptic diversification,phenotypic plasticity and extensive host associations have long complicated accurate identifications of species in this genus.The delimitation of the generic type species Diaporthe eres has been uncertain due to the lack of ex-type cultures.Species limits of D.eres and closely related species were evaluated using molecular phylogenetic analysis of eight genes including nuclear ribosomal internal transcribed spacer(ITS),partial sequences of actin(ACT),DNA-lyase(Apn2),translation elongation factor 1-α(EF1-α),beta-tubulin(TUB),calmodulin(CAL),60s ribosomal protein L37(FG1093)and histone-3(HIS).The occurrence of sequence heterogeneity of ITS within D.eres is observed,which complicates the analysis and may lead to overestimation of the species diversity.The strict criteria of Genealogical Concordance Phylogenetic Species Recognition(GCPSR)were applied to resolve species boundaries based on individual and combined analyses of other seven genes except the ITS.We accept nine distinct phylogenetic species including Diaporthe alleghaniensis,D.alnea,D.bicincta,D.celastrina,D.eres,D.helicis,D.neilliae,D.pulla and D.vaccinii.Epitypes are designated for D.alnea,D.bicincta,D.celastrina,D.eres,D.helicis and D.pulla.Modern descriptions and illustrations are provided for these species.Newly designed primers are introduced to amplify and sequence the Apn2(DNA-lyase)gene in Diaporthe.Based on phylogenetic informativeness profiles,EF1-α,Apn2 and HIS genes are recognised as the best markers for defining species in the D.eres complex. 展开更多

One hundred and five generic types of Pleosporales are described and illustrated.A brief introduction and detailed history with short notes on morphology,molecular phylogeny as well as a general conclusion of each genus are provided.For those genera where the type or a representative specimen is unavailable,a brief note is given.Altogether 174 genera of Pleosporales are treated.Phaeotrichaceae as well as Kriegeriella,Zeuctomorpha and Muroia are excluded from Pleosporales.Based on the multigene phylogenetic analysis,the suborder Massarineae is emended to accommodate five families,viz.Lentitheciaceae,Massarinaceae,Montagnulaceae,Morosphaeriaceae and Trematosphaeriaceae. 展开更多
