Botryosphaerialean fungi associated with woody oil plants cultivated in Sichuan Province, China

Woody oil plants are important economic trees which are widely cultivated and distributed throughout China. Surveys conducted during 2020 and 2021 on several woody oil plantations from five regions of Sichuan Province, China, revealed a high diversity of Botryosphaerialean fungi. The identification of 50 botryosphaeriaceous isolates was carried out based on both morphology and multi-gene phylogenetic analysis of internal transcribed spacer region (ITS), translation elongation factor 1-alpha gene (tef1) and β-tubulin gene (tub2). This allowed the identification of twelve previously known Botryosphaeriales species: Aplosporella prunicola, A. ginkgonis, Barriopsis tectonae, Botryosphaeria dothidea, Bo. fabicerciana, Diplodia mutila, Di. seriata, Dothiorella sarmentorum, Neofusicoccum parvum, Sardiniella guizhouensis, Sphaeropsis citrigena, and Sp. guizhouensis, and four novel species belonging to the genera Diplodia and Dothiorella, viz. Di. acerigena, Di. pistaciicola, Do. camelliae and Do. zanthoxyli. The dominant species isolated across the surveyed regions were Botryosphaeria dothidea, Sardiniella guizhouensis and Diplodia mutila, representing 20%, 14% and 12% of the total isolates, respectively. In addition, most isolates were obtained from Pistacia chinensis (14 isolates), followed by Camellia oleifera (10 isolates). The present study enhances the understanding of Botryosphaeriales species diversity on woody oil plants in Sichuan Province, China

Naming and outline of Dothideomycetes-2014 including proposals for the protection or suppression of generic names

Article 59.1, of the International Code of Nomenclature for Algae, Fungi, and Plants (ICN; Melbourne Code), which addresses the nomenclature of pleomorphic fungi, became effective from 30 July 2011. Since that date, each fungal species can have one nomenclaturally correct name in a particular classification. All other previously used names for this species will be considered as synonyms. The older generic epithet takes priority over the younger name. Any widely used younger names proposed for use, must comply with Art. 57.2 and their usage should be approved by the Nomenclature Committee for Fungi (NCF). In this paper, we list all genera currently accepted by us in Dothideomycetes (belonging to 23 orders and 110 families), including pleomorphic and nonpleomorphic genera. In the case of pleomorphic genera, we follow the rulings of the current ICN and propose single generic names for future usage. The taxonomic placements of 1261 genera are listed as an outline. Protected names and suppressed names for 34 pleomorphic genera are listed separately. Notes and justifications are provided for possible proposed names after the list of genera. Notes are also provided on recent advances in our understanding of asexual and sexual morph linkages in Dothideomycetes. A phylogenetic tree based on four gene analyses supported 23 orders and 75 families, while 35 families still lack molecular data

Morpho-Phylogenetic Evidence Reveals Novel Species and New Records of <i>Botryosphaeriaceae</i> in China and Thailand

Species in the Botryosphaeriaceae are common plant pathogens, endophytes, and saprobes found on a variety of mainly woody hosts. Botryosphaeriaceae is a high-profile fungal family whose genera have been subjected to continuous revisions in recent years. Surveys conducted during 2019 and 2020 on several decaying woody hosts (from dead arial twigs, branches, stems, bark, and seed pods) in China and Thailand revealed a high diversity of Botryosphaeriaceae fungi. Identification of 16 Botryosphaeriaceae isolates was carried out based on both morphological characteristics and phylogenetic analyses of combined ITS, LSU, tef1-α, and tub2 sequence data. Four novel species (Dothiorella ovata, Do. rosacearum, Do. septata, and Lasiodiplodia delonicis) and seven previously known species (Botryosphaeria fujianensis, Diplodia mutila, Di. seriata, L. crassispora, L. mahajangana, Macrophomina euphorbiicola and Sphaeropsis eucalypticola) were identified while new hosts and geographical records were reported. This study indicates that the fungal family Botryosphaeriaceae seems to be common and widespread on a broad range of hosts in China and Thailand

Identification and Pathogenicity of Pestalotiod Fungi Associated with Woody Oil Plants in Sichuan Province, China

Pestalotiod fungi are associated with a wide variety of plants worldwide and occur as endophytes, pathogens, and saprobes. The present study provides an updated phylogeny for genera Neopestalotiopsis, Pestalotiopsis, and Seiridium using fresh collections from woody oil plants (Camellia oleifera, Olea europaea, Paeonia suffruticosa, Sapium sebiferum, and Vernicia fordii) in Sichuan Province, China. We coupled morphology and combined sequence data analyses of ITS, tub2, and tef1-&alpha; for Neopestalotiopsis and Pestalotiopsis, with ITS, LSU, tub2, tef1-&alpha;, and rpb2 for Seiridium. Three novel species of Neopestalotiopsis (N. mianyangensis, N. paeonia-suffruticosa, N. terricola) and three of Seiridium (S. guangyuanum, S. vernicola,&nbsp;S. oleae), were found. Three other species, Pestalotiopsis kenyana, Seiridium ceratosporum, and S. rosarum were identified and reported as new records. All isolated species are fully described and illustrated. Additionally, the sexual morph of Pestalotiopsis kenyana is described for the first time. Pathogenicity tests revealed that Neopestalotiopsis mianyangensis, N. paeonia-suffruticosa, N. terricola, Pestalotiopsis kenyana, Seiridium guangyuanum, S. vernicola, and S. oleae are pathogenic on detached olive leaves
