However, recent changes in the taxonomy of fungi following the one fungus = one name initiative and the implementation of DNA phylogeny in taxonomic revisions, resulted in many changes of these species names, necessitating an update of the current list. In addition, many quarantine fungi lack modern morphological descriptions and authentic DNA sequences, posing significant challenges for the development of diagnostic protocols. The aim of the present study was to review the taxonomy and names of the 33 Chinese quarantine fungi in <i>Dothideomycetes</i>, and provide reliable DNA barcodes to facilitate rapid identification. Of these, 23 names were updated according to the single name nomenclature system, including one new combination, namely <i>Cophinforma tumefaciens</i> comb. nov. (syn. <i>Sphaeropsis tumefaciens</i>)<i>.</i> On the basis of phylogenetic analyses and morphological comparisons, a new genus <i>Xenosphaeropsis</i> is introduced to accommodate the monotypic species <i>Xenosphaeropsis pyriputrescens</i> comb. nov. (syn. <i>Sphaeropsis pyriputrescens</i>), the causal agent of a post-harvest disease of pears. Furthermore, four lectotypes (<i>Ascochyta petroselini</i>, <i>Mycosphaerella ligulicola</i>, <i>Physalospora laricina</i>, <i>Sphaeria lingam</i>), three epitypes (<i>Ascochyta petroselini</i>, <i>Phoma lycopersici</i>, <i>Sphaeria lingam</i>), and two neotypes (<i>Ascochyta pinodella</i>, <i>Deuterophoma tracheiphila</i>) are designated to stabilise the use of these names. A further four reference strains are introduced for <i>Cophinforma tumefaciens</i>, <i>Helminthosporium solani</i>, <i>Mycocentrospora acerina</i>, and <i>Septoria linicola</i>. In addition, to assist future studies on these important pathogens, we sequenced and assembled whole genomes for 17 species, including <i>Alternaria triticina</i>, <i>Boeremia foveata</i>, <i>B. lycopersici</i>, <i>Cladosporium cucumerinum</i>, <i>Didymella glomerata</i>, <i>Didymella pinodella</i>, <i>Diplodia mutila</i>, <i>Helminthosporium solani</i>, <i>Mycocentrospora acerina</i>, <i>Neofusicoccum laricinum</i>, <i>Parastagonospora pseudonodorum</i>, <i>Plenodomus libanotidis</i>, <i>Plenodomus lingam</i>, <i>Plenodomus tracheiphilus</i>, <i>Septoria petroselini</i>, <i>Stagonosporopsis chrysanthemi</i>, and <i>Xenosphaeropsis pyriputrescens</i>. <b>Citation</b>: Zhao P, Crous PW, Hou LW, et al. 2021.

In this study we present a polyphasic taxonomy regarding two widely distributed complexes of <i>Beauveria</i>: <i>B. asiatica</i> and <i>B. bassiana</i> s.lat. Some of the genetic groups as previously detected within both taxa were either confirmed or fused using population genomics. High levels of divergence were found between two clades in <i>B. asiatica</i> and among three clades in <i>B. bassiana</i>, supporting their subdivision as distinct species. Morphological examination focusing on the width and the length of phialides and conidia showed no difference among the clades within <i>B. bassiana</i> while conidial length was significantly different among clades within <i>B. asiatica</i>. The secondary metabolite profiles obtained by liquid chromatography-mass spectrometry (LC-MS) allowed a distinction between <i>B. asiatica</i> and <i>B. bassiana</i>, but not between the clades therein. Based on these genomic, morphological, chemical data, we proposed a clade of <i>B. asiatica</i> as a new species, named <i>B. thailandica</i>, and two clades of <i>B. bassiana</i> to respectively represent <i>B. namnaoensis</i> and <i>B. neobassiana</i> spp. nov.

Although the species of fungal diseases of leaves and fruits have been extensively studied, the causal organisms of branch diseases remain poorly known in China. Species of <i>Botryosphaeriaceae</i> are known as important fungal pathogens causing branch diseases on citrus in the USA and Europe. To determine the diversity of <i>Botryosphaeriaceae</i> species associated with citrus branch diseases in China, surveys were conducted in the major citrus-producing areas from 2017 to 2020. Diseased tissues were collected from twigs, branches and trunks with a range of symptoms including cankers, cracking, dieback and gummosis. Based on morphological characteristics and phylogenetic comparison of the DNA sequences of the internal transcribed spacer region (ITS), the translation elongation factor 1-alpha gene (<i>tef1</i>), the β-tubulin gene (<i>tub2</i>) and the DNA-directed RNA polymerase II second largest subunit (<i>rpb2</i>), 111 isolates from nine provinces were identified as 18 species of <i>Botryosphaeriaceae</i>, including <i>Botryosphaeria dothidea</i>, <i>B. fabicerciana</i>, <i>Diplodia seriata</i>, <i>Dothiorella alpina</i>, <i>Do. plurivora</i>, <i>Lasiodiplodia citricola</i>, <i>L. iraniensis</i>, <i>L. microconidia</i>, <i>L. pseudotheobromae</i>, <i>L. theobromae</i>, <i>Neodeightonia subglobosa</i>, <i>Neofusicoccum parvum</i>, and six previously undescribed species, namely <i>Do. citrimurcotticola</i>, <i>L.</i> <i>guilinensis</i>, <i>L. huangyanensis</i>, <i>L. linhaiensis</i>, <i>L. ponkanicola</i> and <i>Sphaeropsis linhaiensis</i> spp. nov. <i>Botryosphaeria dothidea</i> (28.8 %) was the most abundant species, followed by <i>L. pseudotheobromae</i> (23.4 %), which was the most widely distributed species on citrus, occurring in six of the nine provinces sampled. Pathogenicity tests indicated that all 18 species of <i>Botryosphaeriaceae</i> obtained from diseased citrus tissues in this study were pathogenic to the tested <i>Citrus reticulata</i> shoots <i>in vitro</i>, while not all species are pathogenic to the tested Cocktail grapefruit (<i>C. paradisi</i> × <i>C. reticulata</i>) shoots <i>in vivo</i>. In addition, <i>Lasiodiplodia</i> was the most aggressive genus both <i>in vitro</i> and <i>in vivo</i>.

This review will aid federal and state governments in risk assessments and trade negotiations by providing a comprehensive resource on the current status of <i>Phytophthora</i> species in Australia. <b>Citation:</b> Burgess TI, Edwards J, Drenth A, et al. 2021.

However, recent changes in the taxonomy of fungi following the one fungus = one name initiative and the implementation of DNA phylogeny in taxonomic revisions, resulted in many changes of these species names, necessitating an update of the current list. In addition, many quarantine fungi lack modern morphological descriptions and authentic DNA sequences, posing significant challenges for the development of diagnostic protocols. The aim of the present study was to review the taxonomy and names of the 33 Chinese quarantine fungi in <i>Dothideomycetes</i>, and provide reliable DNA barcodes to facilitate rapid identification. Of these, 23 names were updated according to the single name nomenclature system, including one new combination, namely <i>Cophinforma tumefaciens</i> comb. nov. (syn. <i>Sphaeropsis tumefaciens</i>)<i>.</i> On the basis of phylogenetic analyses and morphological comparisons, a new genus <i>Xenosphaeropsis</i> is introduced to accommodate the monotypic species <i>Xenosphaeropsis pyriputrescens</i> comb. nov. (syn. <i>Sphaeropsis pyriputrescens</i>), the causal agent of a post-harvest disease of pears. Furthermore, four lectotypes (<i>Ascochyta petroselini</i>, <i>Mycosphaerella ligulicola</i>, <i>Physalospora laricina</i>, <i>Sphaeria lingam</i>), three epitypes (<i>Ascochyta petroselini</i>, <i>Phoma lycopersici</i>, <i>Sphaeria lingam</i>), and two neotypes (<i>Ascochyta pinodella</i>, <i>Deuterophoma tracheiphila</i>) are designated to stabilise the use of these names. A further four reference strains are introduced for <i>Cophinforma tumefaciens</i>, <i>Helminthosporium solani</i>, <i>Mycocentrospora acerina</i>, and <i>Septoria linicola</i>. In addition, to assist future studies on these important pathogens, we sequenced and assembled whole genomes for 17 species, including <i>Alternaria triticina</i>, <i>Boeremia foveata</i>, <i>B. lycopersici</i>, <i>Cladosporium cucumerinum</i>, <i>Didymella glomerata</i>, <i>Didymella pinodella</i>, <i>Diplodia mutila</i>, <i>Helminthosporium solani</i>, <i>Mycocentrospora acerina</i>, <i>Neofusicoccum laricinum</i>, <i>Parastagonospora pseudonodorum</i>, <i>Plenodomus libanotidis</i>, <i>Plenodomus lingam</i>, <i>Plenodomus tracheiphilus</i>, <i>Septoria petroselini</i>, <i>Stagonosporopsis chrysanthemi</i>, and <i>Xenosphaeropsis pyriputrescens</i>. <b>Citation</b>: Zhao P, Crous PW, Hou LW, et al. 2021.

Although the species of fungal diseases of leaves and fruits have been extensively studied, the causal organisms of branch diseases remain poorly known in China. Species of <i>Botryosphaeriaceae</i> are known as important fungal pathogens causing branch diseases on citrus in the USA and Europe. To determine the diversity of <i>Botryosphaeriaceae</i> species associated with citrus branch diseases in China, surveys were conducted in the major citrus-producing areas from 2017 to 2020. Diseased tissues were collected from twigs, branches and trunks with a range of symptoms including cankers, cracking, dieback and gummosis. Based on morphological characteristics and phylogenetic comparison of the DNA sequences of the internal transcribed spacer region (ITS), the translation elongation factor 1-alpha gene (<i>tef1</i>), the β-tubulin gene (<i>tub2</i>) and the DNA-directed RNA polymerase II second largest subunit (<i>rpb2</i>), 111 isolates from nine provinces were identified as 18 species of <i>Botryosphaeriaceae</i>, including <i>Botryosphaeria dothidea</i>, <i>B. fabicerciana</i>, <i>Diplodia seriata</i>, <i>Dothiorella alpina</i>, <i>Do. plurivora</i>, <i>Lasiodiplodia citricola</i>, <i>L. iraniensis</i>, <i>L. microconidia</i>, <i>L. pseudotheobromae</i>, <i>L. theobromae</i>, <i>Neodeightonia subglobosa</i>, <i>Neofusicoccum parvum</i>, and six previously undescribed species, namely <i>Do. citrimurcotticola</i>, <i>L.</i> <i>guilinensis</i>, <i>L. huangyanensis</i>, <i>L. linhaiensis</i>, <i>L. ponkanicola</i> and <i>Sphaeropsis linhaiensis</i> spp. nov. <i>Botryosphaeria dothidea</i> (28.8 %) was the most abundant species, followed by <i>L. pseudotheobromae</i> (23.4 %), which was the most widely distributed species on citrus, occurring in six of the nine provinces sampled. Pathogenicity tests indicated that all 18 species of <i>Botryosphaeriaceae</i> obtained from diseased citrus tissues in this study were pathogenic to the tested <i>Citrus reticulata</i> shoots <i>in vitro</i>, while not all species are pathogenic to the tested Cocktail grapefruit (<i>C. paradisi</i> × <i>C. reticulata</i>) shoots <i>in vivo</i>. In addition, <i>Lasiodiplodia</i> was the most aggressive genus both <i>in vitro</i> and <i>in vivo</i>. This is the first study to identify <i>Botryosphaeriaceae</i> species related to citrus branch diseases in China and the results provide a theoretical basis for the implementation of prevention and control measures. <b>Citation</b>: Xiao XE, Wang W, Crous PW, et al. 2021.
