Several resupinate poroid Polyporaceae with dextrinoid skeletal hyphae and cylindrical, thinwalled basidiospores have been placed in Dichomitus and Megasporoporia. 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.
在二孢子门和大孢子门中发现了几种具有糊精状骨架菌丝和圆柱形薄壁担子孢子的复旋孢子多孢子科植物。在该属的系统发育中包含了DNA序列,其中大部分来自中国材料,从而识别出新属,即Megasporoporiella和Megasporia。本研究将Jorgewrightia和Mariorajchenbergia作为水草科植物的新属,分析了它们的4个基因区:ncrdna ITS1-5.8S-ITS (ITS)和部分大亚基(28S)、翻译延伸因子1- α (TEF1)和RNA聚合酶II第二大亚基(RPB2),这些基因区主要来自巴西材料。这些新属目前容纳了以前属于Cerioporus、Dichomitus、Megasporia、Megasporoporiella和Pachykytospora的物种。二分土、Jorgewrightia、Mariorajchenbergia、Megasporia和Megasporoporia主要有复生的浅色担子孢子、多孔膜孢子、通常为糊精状分枝的骨架菌丝和圆柱形担子孢子。这些属很难单独从形态学上进行区分,需要基于至少两个区域(ITS和28S)的序列分析以及地理分布信息来区分它们。大孢子虫(Megasporia variabilicolosa)和新孢子虫(Megasporoporia nesetulosa)被描述为新种,并提出了1个新型和20个新组合。给出了包括5属27种特征在内的分类表。

Investigation of various cheese rinds for Bisifusarium domesticum revealed a completely unexpected diversity of Fusarium-like fungi. 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.).

Camellia sinensis, commonly known as tea, is one of the most economically important crops in China. 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.
茶树(Camellia sinensis),俗称茶,是中国最重要的经济作物之一。茶叶的茎叶坏死是一个值得关注的问题,它直接影响茶叶收获的质量和数量。在本研究中,我们收集了福建省的病叶和病梢,以鉴定与该疾病相关的真菌种类。共分离到110株菌株,通过形态特征和多位点系统发育方法进行了鉴定。鉴定出与茶叶茎叶坏死有关的11科13属32种。新种五种;介绍了茶油毛菌、福建白僵菌、fususiformis、sinensis和camelli木霉。此外,还报道了9个新的宿主记录。这些结果表明茶叶和芽上的物种丰富度较高。此外,还提供了一份世界范围内与C. sinensis相关的真菌清单。本研究结果为中国白桦叶片坏死和梢枯病相关真菌的研究提供了新的思路。然而,需要进一步的研究来了解本研究中发现的物种的致病潜力和生物防治能力。

Cytospora species are important pathogens, which have a worldwide distribution, broad host range and are commonly associated with tree dieback and canker disease. Lack of ex-type cultures or inability to link multi-gene DNA sequence data in GenBank to phylogenetic analyses makes it difficult to classify Cytospora taxa to species level. In this study, ten specimens of Cytospora were collected from dead wood in China, Italy and Thailand. Based on their morphology and phylogenetic characterization, four new species (C. diopuiensis, C. galegicola, C. pingbianensis and C. pubescentis) and four known species (C. cedri, C. cotini, C. predappioensis and C. prunicola) are herein described, illustrated and compared with related taxa. Detailed morphological descriptions of the holomorph (C. galegicola, C. prunicola, C. predappioensis and C. pubescentis), the sexual morph (C. cedri, C. cotini, C. diopuiensis and C. pingbianensis) and a new record of C. predappioensis in China are provided. Phylogenetic analyses of a combined ITS, LSU, ACT and RPB2 DNA sequence dataset support their placement in the genus Cytospora and justify the new species and identification of known species.
胞孢子菌是一种重要的病原菌,分布在世界各地,寄主范围广,通常与树木枯死病和溃疡病有关。缺乏前型培养或无法将GenBank中的多基因DNA序列数据与系统发育分析联系起来,使得很难将胞孢子虫分类群划分到物种水平。本研究从中国、意大利和泰国的枯木中采集了10份胞孢子虫标本。根据其形态和系统发育特征,对4个新种(C. diopuiensis、C. galegicola、C. pingbianensis和C. pubescentis)和4个已知种(C. cedri、C. cotini、C. predappioensis和C. prunicola)进行了描述、说明,并与相关分类群进行了比较。详细描述了全形态(C. galegicola、C. prunicola、C. predpioensis和C. pubescentis)、性形态(C. cedri、C. cotini、C. diopuiensis和C. pingbianensis)和中国新记录的C. preddappioensis。ITS, LSU, ACT和RPB2 DNA序列数据集的系统发育分析支持它们在胞孢子属中的位置,并证明了新种和已知种的鉴定。

Phyllosticta species have worldwide distribution and are pathogens, endophytes, and saprobes. 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.
毛虫分布在世界各地,是病原菌、内生菌和腐殖菌。还从果实的叶斑和黑斑中分离出分类群。由于形态特征和寄主关联的重叠,毛竹属物种的分类鉴定具有挑战性。在此,我们组装了一个全面的数据集,并重建了一个系统发育树。我们介绍了毛竹属植物的6个种复合体,以帮助将来的物种划分。本文还介绍了从台湾红树根茎的斑点叶中分离到的一新种——根茎毛蝗。基于ITS、LSU、ef1α、actin和gapdh位点的组合序列数据,结合形态学证据进行系统发育分析,支持新种的建立。我们将cpc20508和CPC20509同义命名为新种。6株菌株(CBS 173.77、CBS 119720、CPC 17748、CPC 20252、CPC 20269和CBS 123404)经系统发育分析和核苷酸多态性分析为未命名种,可能为新种。对毛竹属植物的系统发育关系进行了重新评价,并对今后的工作提出了建议。

Diatrypaceous fungi on palms (Arecaceae) in Thailand were collected and identified based on morphological characteristics as well as combined DNA sequence analyses (ITS and TUB2). One new genus Allodiatrype, and five new species, Allocryptovalsa elaeidis, Allodiatrype arengae, A. elaeidicola, A. elaeidis and Diatrypella elaeidis are introduced. A checklist of Diatrypaceae occurring on palms (Arecaceae) and Thai diatrypaceous fungi is also provided.
收集了泰国棕榈(槟榔科)上的双栖真菌,通过形态特征和DNA序列分析(ITS和TUB2)对其进行了鉴定。本文介绍了allodiattype新属1个,Allocryptovalsa elaeidis、allodiattype arengae、a.a elaeidicola、a.a elaeidis和Diatrypella elaeidis 5个新种。还提供了一份发生在棕榈(槟榔科)上的双藓科真菌和泰国双藓科真菌的清单。
