With the inclusion of DNA sequences, mostly from Chinese material, in the phylogeny of the genera, new genera were recognized, i.e., Megasporoporiella and Megasporia. In the current study, Jorgewrightia and Mariorajchenbergia are described as new genera in the Polyporaceae based on phylogenetic analyses of four gene regions: nuc rDNA ITS1-5.8S-ITS (ITS) and partial Large Subunit (28S), Translation Elongation Factor 1-alpha (TEF1), and RNA polymerase II second largest subunit (RPB2), mostly from Brazilian material. These new genera currently accommodate species formerly placed in Cerioporus, Dichomitus, Megasporia, Megasporoporiella and Pachykytospora. Dichomitus, Jorgewrightia, Mariorajchenbergia, Megasporia and Megasporoporia have mostly resupinate pale-colored basidiomata, poroid hymenophore, usually dextrinoid branched skeletal hyphae, and cylindrical basidiospores. These genera are difficult to differentiate on morphology alone and analyses based on sequences from at least two regions (ITS and 28S), as well as information about geographical distribution, are needed to separate them. Megasporia variabilicolor and Megasporoporia neosetulosa are described as new species, and one neotype and 20 new combinations are proposed. Synoptic tables including characteristics for 27 species from the five genera is presented.","PeriodicalId":48718,"journal":{"name":"Mycosphere","volume":"1 1","pages":""},"PeriodicalIF":14.6,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71234462","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Elongation factor 1-alpha gene sequence data, classically used for Fusarium spp. identification, suggested that some isolates corresponded to so far undescribed Nectriaceae species. In this context, a multi-gene phylogenetic analysis, based on ten loci, namely the large subunit of the ATP citrate lyase (acl1), alpha-actin (act), calmodulin (cmdA), histone H3 (his3), the internal transcribed spacer region and intervening 5.8S nrRNA (ITS), 28S large subunit (LSU), RNA polymerase II largest subunit (rpb1), RNA polymerase II second largest subunit (rpb2), translation elongation factor 1-alpha (tef1) and β-tubulin (tub2), was therefore performed to determine the phylogenetic position of ten cheese and one environmental isolates. Phylogenetic reconstructions were then done using a Nectriaceae sequence dataset. Additionally, morphological observations as well as metabolite profiling were performed. Results clearly revealed the existence of four novel cheese-associated species, namely Bisifusarium allantoides, Bisifusarium penicilloides, Longinectria lagenoides, Longinectria verticilliforme, the two latter belonging to a novel genus (Longinectria gen. nov.).","PeriodicalId":48718,"journal":{"name":"Mycosphere","volume":"12 1","pages":"1077-1100"},"PeriodicalIF":14.6,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71233725","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Shoot and leaf necrosis in tea is of considerable concern as it directly affects the quality and quantity of tea leaf harvest. In the present study, diseased leaves and shoots were collected from Fujian Province to identify the fungal species associated with the disease. In total 110 strains were isolated and they were identified by morphological characteristics and multi-locus phylogenetic approaches. Thirty–two species belonging to 13 genera and 11 families associated with shoot and leaf necrosis of tea were identified. Five new species; Chaetomium camelliae, Diaporthe fujianensis, D. fusiformis, D. sinensis and Trichoderma camelliae are introduced. In addition, nine novel host records are reported. These results indicate high species richness on tea leaves and shoots. In addition, a checklist for fungi associated with C. sinensis worldwide is provided. Information presented in this study provides new insights into fungi associated with leaf necrosis and shoot blight of C. sinensis in China. However, further studies are necessary to understand the pathogenic potential and biocontrol ability of the species identified in this study.","PeriodicalId":48718,"journal":{"name":"Mycosphere","volume":"1 1","pages":""},"PeriodicalIF":14.6,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71234428","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Taxa have also been isolated from leaf spots and black spots of fruits. Taxonomic identification of Phyllosticta species is challenging due to overlapping morphological traits and host associations. Herein, we have assembled a comprehensive dataset and reconstructed a phylogenetic tree. We introduce six species complexes of Phyllosticta to aid the future resolution of species. We also introduce a new species, Phyllosticta rhizophorae isolated from spotted leaves of Rhizophora stylosa in mangrove forests of Taiwan. Phylogenetic analysis based on combined sequence data of ITS, LSU, ef1α, actin and gapdh loci coupled with morphological evidence support the establishment of the new species. We synonymize strains of P. capitalensis (CPC 20508 and CPC20509) under the new species. Six strains (CBS 173.77, CBS 119720, CPC 17748, CPC 20252, CPC 20269, and CBS 123404) are unnamed species based on phylogenetic analyses and nucleotide polymorphisms and probably represent new species. The phylogenetic relationships of Phyllosticta species are reappraised and suggestions are given for future work.","PeriodicalId":48718,"journal":{"name":"Mycosphere","volume":"11 1","pages":"2542-2628"},"PeriodicalIF":14.6,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71233236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
