Glutinoglossum is one of the earth tongue genera with viscid or glutinous ascocarps. Based on morphology and ITS1-5.8S-ITS2, nrLSU and tef1 sequence data, seven new species are described: G. circinatum, G. lumbricale, G. orientale, G. peregrinans, G. proliferatum, G. pseudoglutinosum, and G. triseptatum. The lectotypes for Geoglossum glutinosum var. lubricum and for Geoglossum glabrum var. majus as well as the epitype for Glutinoglossum glutinosum are designated. The comprehensive morphological study of G. heptaseptatum resulted in the discovery of ascospores germinating by conidia inside the asci, which is first noted for Glutinoglossum species. The status of Cibalocoryne is discussed.

粘舌属是具有粘性或粘性子囊的土舌属之一。基于形态学和ITS1-5.8S-ITS2、nrLSU和tef1序列数据,描述了7个新种:G. circinatum、G. lumbricale、G. orientale、G. peregrinans、G. proliferatum、G. pseudoglutinosum和G. triseptatum。确定了黄黄地舌鼠和大黄地舌鼠的选型,并确定了黄黄地舌鼠的表型。对G. heptaseptatum进行了全面的形态学研究,发现了由分生孢子在子囊内萌发的子囊孢子,这是在gluinoglosum种中首次发现的。讨论了西巴罗科林的现状。

Uromycladium tepperianum has been reported on over 100 species of Acacia, as well as on the closely related plant genera, Falcataria, Racosperma and Paraserianthes. Previous studies have indicated that U. tepperianum may represent a complex of host-specific, cryptic species. The phylogenetic relationships between 79 specimens of Uromycladium were determined based on a concatenated dataset of the Small Subunit, the Internal Transcribed Spacer and the Large Subunit regions of nuclear ribosomal DNA, and the mitochondrial cytochrome c oxidase subunit 3. This study showed that the host range of U. tepperianum s.str. was restricted to species of Acacia in the 'A. bivenosa group' sensu Chapman & Maslin (1992). An epitype of U. tepperianum on A. ligulata is designated to create a stable taxonomy for the application of this name. Sixteen novel species of Uromycladium are described, based on host preference, morphology and a phylogenetic species concept.

Seiridium (Sporocadaceae): an important genus of plant pathogenic fungi. 孢子菌科:一种重要的植物病原真菌属。
IF 9.1 1区 生物学 Q1 Agricultural and Biological Sciences Pub Date : 2018-12-01 Epub Date: 2018-01-09 DOI: 10.3767/persoonia.2018.40.04

The genus Seiridium includes multiple plant pathogenic fungi well-known as causal organisms of cankers on Cupressaceae. Taxonomically, the status of several species has been a topic of debate, as the phylogeny of the genus remains unresolved and authentic ex-type cultures are mostly absent. In the present study, a large collection of Seiridium cultures and specimens from the CBS and IMI collections was investigated morphologically and phylogenetically to resolve the taxonomy of the genus. These investigations included the type material of the most important Cupressaceae pathogens, Seiridium cardinale, S. cupressi and S. unicorne. We constructed a phylogeny of Seiridium based on four loci, namely the ITS rDNA region, and partial translation elongation factor 1-alpha (TEF), β-tubulin (TUB) and RNA polymerase II core subunit (RPB2). Based on these results we were able to confirm that S. unicorne and S. cupressi represent different species. In addition, five new Seiridium species were described, S. cupressi was lectotypified and epitypes were selected for S. cupressi and S. eucalypti.

Seiridium属包括多种植物病原真菌,被认为是柏科溃疡病的致病生物。在分类学上,一些物种的地位一直是一个有争议的话题,因为该属的系统发育仍未解决,而且大多数没有真正的前型文化。本研究对CBS和IMI收集的大量Seiridium培养物和标本进行了形态学和系统发育研究,以确定该属的分类。这些调查包括了最重要的柏科病原菌的类型材料,即红柏树、柏树和独角兽。我们基于ITS rDNA区域、部分翻译延伸因子1- α (TEF)、β-微管蛋白(TUB)和RNA聚合酶II核心亚基(RPB2)四个位点构建了Seiridium的系统发育。基于这些结果,我们能够证实独角兽和柏树代表不同的物种。此外,还发现了5个新种,并对柏树和桉树进行了选型和选型。

In this study we accept 25 families in Diaporthales based on phylogenetic analyses using partial ITS, LSU, rpb2 and tef1-α gene sequences. Four different families associated with canker and dieback of tree hosts are morphologically treated and phylogenetically compared. These include three new families (Diaporthostomataceae, Pseudomelanconidaceae, Synnemasporellaceae), and one new genus, Dendrostoma (Erythrogloeaceae). Dendrostoma is newly described from Malus spectabilis, Osmanthus fragrans and Quercus acutissima having fusoid to cylindrical, bicellular ascospores, with three new species namely D. mali, D. osmanthi and D. quercinum. Diaporthostomataceae is characterised by conical and discrete perithecia with bicellular, fusoid ascospores on branches of Machilus leptophylla. Pseudomelanconidaceae is defined by conidiogenous cells with apical collarets and discreet annellations, and the inconspicuous hyaline conidial sheath when mature on Carya cathayensis, compared to morphologically similar families Melanconidaceae and Juglanconidaceae. Synnemasporellaceae is proposed to accommodate fungi with synnematous conidiomata, with descriptions of S. toxicodendri on Toxicodendron sylvestre and S. aculeans on Rhus copallina.

本研究采用ITS、LSU、rpb2和tef1-α部分基因序列进行系统发育分析。对与树宿主溃疡病和枯死病相关的四个不同家族进行了形态学处理和系统发育比较。其中包括3个新科(Diaporthostomataceae, Pseudomelanconidaceae, Synnemasporellaceae)和1个新属(Dendrostoma, Erythrogloeaceae)。树孢子是在苹果、桂花和麻栎中发现的一种具有梭状至柱状双细胞子囊孢子的新物种,其中有3个新种,即马利、桂花和槲皮。斜口科的特征是圆锥形和离散的周皮,双细胞的,柔丝样子囊孢子在细枝上。与形态相似的黑孢孢子科和胡桃孢子科相比,假黑孢孢子科的定义是在山核桃上成熟的分生细胞具有顶端的苞片和不明显的环状花序,成熟时有不明显的透明分生孢子鞘。提出了联系性分生菌科,以适应具有联系性分生菌的真菌,并描述了毒蕈(S. toxicodendri)在毒蕈(Toxicodendron sylvestre)上的分布,以及毒蕈(S. acules)在Rhus copallina上的分布。

New Ceratocystis species associated with rapid death of Metrosideros polymorpha in Hawai'i. 与夏威夷多形田鼠快速死亡有关的角鼻虫新种。

The native 'ōhi'a lehua (Metrosideros polymorpha) has cultural, biological and ecological significance to Hawai'i, but it is seriously threatened by a disease commonly referred to as rapid 'ōhi'a death (ROD). Preliminary investigations showed that a Ceratocystis species similar to C. fimbriata s.lat. was the cause of the disease. In this study, we used a combination of the phylogenetic, morphological and biological species concepts, as well as pathogenicity tests and microsatellite analyses, to characterise isolates collected from diseased 'ōhi'a trees across Hawai'i Island. Two distinct lineages, representing new species of Ceratocystis, were evident based on multigene phylogenetic analyses. These are described here as C. lukuohia and C. huliohia. Ceratocystis lukuohia forms part of the Latin American clade (LAC) and was most closely associated with isolates from Syngonium and Xanthosoma from the Caribbean and elsewhere, including Hawai'i, and C. platani, which is native to eastern USA. Ceratocystis huliohia resides in the Asian-Australian clade (AAC) and is most closely related to C. uchidae, C. changhui and C. cercfabiensis, which are thought to be native to Asia. Morphology and interfertility tests support the delineation of these two new species and pathogenicity tests show that both species are aggressive pathogens on seedlings of M. polymorpha. Characterisation of isolates using microsatellite markers suggest that both species are clonal and likely represent recently-introduced strains. Intensive research is underway to develop rapid screening protocols for early detection of the pathogens and management strategies in an attempt to prevent the spread of the pathogens to the other islands of Hawai'i, which are currently disease free.

当地的'ōhi'a乐花(Metrosideros polymorpha)对夏威夷具有文化、生物和生态意义,但它受到一种通常被称为'ōhi'a快速死亡(ROD)的疾病的严重威胁。初步调查发现一种角鼻虫属,与C. fibriata s.lat相似。是导致疾病的原因。在这项研究中,我们结合了系统发育、形态和生物物种概念,以及致病性测试和微卫星分析,对从夏威夷岛上患病的“ōhi”树中收集的分离物进行了表征。在多基因系统发育分析的基础上,发现了两个不同的分支,代表了角鼻虫的新种。这里描述的是C. lukuohia和C. huliohia。lukuohia角鼻虫(Ceratocystis lukuohia)是拉丁美洲分支(LAC)的一部分,与来自加勒比海和其他地方(包括夏威夷)的Syngonium和Xanthosoma分离株以及原产于美国东部的C. platani最密切相关。huliohia角鼻虫(Ceratocystis huliohia)属于亚洲-澳大利亚分支(AAC),与原产于亚洲的C. uchidae、C. changhui和C. cercfabiensis亲缘关系最密切。形态学和杂交试验支持这两个新种的描述,致病性试验表明这两个物种都是多形草幼苗的侵袭性病原体。利用微卫星标记对分离物进行鉴定表明,这两个物种都是无性系,很可能代表最近引进的菌株。目前正在进行深入研究,以制定早期发现病原体的快速筛选方案和管理战略,以防止病原体传播到目前没有疾病的夏威夷其他岛屿。

Botryosphaeriaceae from Eucalyptus plantations and adjacent plants in China. 标题中国桉树人工林及其邻近植物的灰桉科植物。
IF 9.1 1区 生物学 Q1 Agricultural and Biological Sciences Pub Date : 2018-12-01 Epub Date: 2017-10-31 DOI: 10.3767/persoonia.2018.40.03

The Botryosphaeriaceae is a species-rich family that includes pathogens of a wide variety of plants, including species of Eucalyptus. Recently, during disease surveys in China, diseased samples associated with species of Botryosphaeriaceae were collected from plantation Eucalyptus and other plants, including Cunninghamina lanceolata, Dimocarpus longan, Melastoma sanguineum and Phoenix hanceana, which were growing adjacent to Eucalyptus. In addition, few samples from Araucaria cunninghamii and Cedrus deodara in two gardens were also included in this study. Disease symptoms observed mainly included stem canker, shoot and twig blight. In this study, 105 isolates of Botryosphaeriaceae were collected from six provinces, of which 81 isolates were from Eucalyptus trees. These isolates were identified based on comparisons of the DNA sequences of the internal transcribed spacer regions and intervening 5.8S nrRNA gene (ITS), and partial translation elongation factor 1-alpha (tef1), β-tubulin (tub), DNA-directed RNA polymerase II subunit (rpb2) and calmodulin (cmdA) genes, the nuclear ribosomal large subunit (LSU) and the nuclear ribosomal small subunit (SSU), and combined with their morphological characteristics. Results showed that these isolates represent 12 species of Botryosphaeriaceae, including Botryosphaeria fusispora, Cophinforma atrovirens, Lasiodiplodia brasiliense, L. pseudotheobromae, L. theobromae and Neofusicoccum parvum, and six previously undescribed species of Botryosphaeria and Neofusicoccum, namely B. pseudoramosa sp. nov., B. qingyuanensis sp. nov., B. wangensis sp. nov., N. hongkongense sp. nov., N. microconidium sp. nov. and N. sinoeucalypti sp. nov. Aside from B. wangensis, C. atrovirens and N. hongkongense, the other nine Botryosphaeriaceae species were isolated from Eucalyptus trees in South China. Botryosphaeria fusispora (26 % of the isolates from Eucalyptus) is the dominant species, followed by L. pseudotheobromae (23 % of the isolates from Eucalyptus). In addition to species found on Eucalyptus trees, we also found B. pseudoramosa on M. sanguineum; B. wangensis on C. deodara; C. atrovirens on D. longan; L. theobromae on C. lanceolata, D. longan and P. hanceana; and N. hongkongense on A. cunninghamii. Pathogenicity tests showed that the 12 species of Botryosphaeriaceae are pathogenic to three Eucalyptus clones and that Lasiodiplodia species are the most aggressive. The results of our study suggest that many more species of the Botryosphaeriaceae remain to be discovered in China. This study also provides confirmation for the

Botryosphaeriaceae是一个物种丰富的家族,包括各种植物的病原体,包括桉树物种。近年来,在中国进行的疾病调查中,从桉树人工林以及与桉树相邻生长的杉木、龙眼、银杏、凤凰树等植物中,采集到了与葡萄树科植物相关的病样。此外,两个园林的杉木和杉木的少量样本也被纳入本研究。主要表现为茎溃疡病、茎枯病和枝条枯病。本研究共从6个省份收集了105株植物,其中桉树属植物分离株81株。通过比较其内部转录间隔区和介入5.8S nrRNA基因(ITS)、部分翻译延伸因子1- α (tef1)、β-微管蛋白(tub)、DNA定向RNA聚合酶II亚基(rpb2)和钙调素(cmdA)基因、核糖体大亚基(LSU)和核糖体小亚基(SSU)的DNA序列,并结合其形态特征进行鉴定。结果表明,这些分离物代表了12种植物,包括fusispora Botryosphaeria、Cophinforma atrovirens、Lasiodiplodia brasiliense、pseudotheobrome、l.e obrome和Neofusicoccum parvum,以及6种植物和Neofusicoccum,分别是pseudooramosa sp. nov、b.e qingyuanensis sp. nov、b.s wangensis sp. nov、b.s honggense sp. nov、b.s microconidium sp. nov和n.s sino桉树sp. nov。C. atrovirens和N. hongkongense,以及其他9种botryosphaeriiaceae植物均从中国南方桉树中分离得到。fusispora葡萄球孢菌(占桉树分离株的26%)是优势菌种,其次是假可可菌(占桉树分离株的23%)。除了在桉树上发现的物种外,我们还在血杨上发现了假芽孢杆菌;王氏双歧杆菌寄生于deodara上;D.龙眼;茶屈菌对杉木、龙眼和雪碧的影响;香港野生种和香港野生种。致病性试验表明,12种botryosphaeriiaceae植物对3个桉树无性系均有致病性,其中Lasiodiplodia种对桉树无性系的致病性最强。我们的研究结果表明,在中国仍有更多的蕨类植物有待发现。本研究也证实了球孢菌科植物在不同植物上寄主范围广泛。

Broad host range species in specialised pathogen groups should be treated with suspicion - a case study on Entyloma infecting Ranunculus. 对特殊病原体群中寄主范围广泛的物种应持怀疑态度--关于 Entyloma 感染毛茛的案例研究。

Plant pathogenic smut fungi in the broader sense can be divided into the Ustilaginomycetes, which cause classical smut symptoms with masses of blackish spores being produced in a variety of angiosperms, and the Exobasidiomycetes, which are often less conspicuous, as many do not shed large amounts of blackish spores. The leaf-spot causing members of the genus Entyloma (Entylomatales, Exobasidiomycetes) belong to the latter group. Currently, 172 species that all infect eudicots are included in the genus. Vánky (2012) recognised five Entyloma species on species of Ranunculus s.lat. Two have been reported only from Ficaria verna s.lat., while three, E. microsporum, E. ranunculi-repentis, E. verruculosum, have been reported to have a broad host range, encompassing 30, 26, and 5 species of Ranunculus, respectively. This broad host range is in contrast to the generally high host specificity assumed for species of Entyloma, indicating that they may represent complexes of specialised species. The aim of this study was to investigate Entyloma on Ranunculus s.lat. using multigene phylogenies and morphological comparisons. Phylogenetic analyses on the basis of up to four loci (ITS, atp2, ssc1, and map) showed a clustering of Entyloma specimens according to host species. For some of these Entyloma lineages, names not currently in use were available and reinstated. In addition, Entyloma microsporum s.str. is neotypified. Six novel species are described in this study, namely, Entyloma jolantae on Ranunculus oreophilus, E. klenkei on R. marginatus, E. kochmanii on R. lanuginosus, E. piepenbringiae on R. polyanthemos subsp. nemorosus (type host) and R. repens, E. savchenkoi on R. paludosus, and E. thielii on R. montanus. For all species diagnostic bases and morphological characteristics are provided. The results in this study once more highlight the importance of detailed re-investigation of broad host-range pathogens of otherwise specialised plant pathogen groups.

广义上的植物致病烟粉虱真菌可分为子囊霉菌(Ustilaginomycetes)和外基枝霉菌(Exobasidiomycetes)两类,前者可引起典型的烟粉虱症状,在各种被子植物中产生大量黑色孢子;后者通常不那么显眼,因为许多真菌不会脱落大量黑色孢子。导致叶斑病的 Entyloma 属(Entylomatales,外担子菌纲)属于后一类。目前,该属共有 172 个物种,均感染裸子植物。Vánky(2012 年)发现五种 Entyloma 物种侵染拉丁蔷薇(Ranunculus s.lat.)。据报道,其中两个仅在藜科镰刀属(Ficaria verna s.lat.)中出现,而另外三个(E. microsporum、E. ranunculi-repentis 和 E. verruculosum)的寄主范围很广,分别包括 30 种、26 种和 5 种 Ranunculus。这种广泛的寄主范围与一般认为 Entyloma 物种具有高度寄主专一性形成了鲜明对比,表明它们可能是专化物种的复合体。本研究的目的是利用多基因系统发育和形态学比较研究小牡丹上的 Entyloma。基于四个基因位点(ITS、atp2、ssc1 和 map)的系统发育分析表明,Entyloma 标本可根据寄主物种进行聚类。对于其中的一些 Entyloma 品系,目前未使用的名称已经出现并被恢复。此外,Entyloma microsporum s.str.也被重新定型。本研究描述了 6 个新种,即 R. Ranunculus oreophilus 上的 Entyloma jolantae、R. marginatus 上的 Entyloma klenkei、R. lanuginosus 上的 Entyloma kochmanii、R. polyanthemos subsp.所有物种都提供了诊断依据和形态特征。这项研究的结果再次凸显了对具有广泛寄主范围的植物病原体类群进行详细再调查的重要性。

Morphological reassessment and molecular phylogenetic analyses of Amauroderma s.lat. raised new perspectives in the generic classification of the Ganodermataceae family. 黑皮病的形态重评价及分子系统发育分析。提出了灵芝科属分类的新观点。

Ganodermataceae is a remarkable group of polypore fungi, mainly characterized by particular double-walled basidiospores with a coloured endosporium ornamented with columns or crests, and a hyaline smooth exosporium. In order to establish an integrative morphological and molecular phylogenetic approach to clarify relationship of Neotropical Amauroderma s.lat. within the Ganodermataceae family, morphological analyses, including scanning electron microscopy, as well as a molecular phylogenetic approach based on one (ITS) and four loci (ITS-5.8S, LSU, TEF-1α and RPB1), were carried out. Ultrastructural analyses raised up a new character for Ganodermataceae systematics, i.e., the presence of perforation in the exosporium with holes that are connected with hollow columns of the endosporium. This character is considered as a synapomorphy in Foraminispora, a new genus proposed here to accommodate Porothelium rugosum (≡ Amauroderma sprucei). Furtadoa is proposed to accommodate species with monomitic context: F. biseptata, F. brasiliensis and F. corneri. Molecular phylogenetic analyses confirm that both genera grouped as strongly supported distinct lineages out of the Amauroderma s.str. clade.

灵芝科是一种显著的多孔真菌,其主要特征是特殊的双壁担子孢子,具有彩色的孢子囊和透明光滑的孢子囊。为了建立一种完整的形态学和分子系统发育方法来阐明新热带黑皮病的亲缘关系。对灵芝科植物进行了形态学分析,包括扫描电镜和基于ITS-5.8 s、LSU、TEF-1α和RPB1位点的分子系统发育分析。超微结构分析发现了灵芝科植物系统学的一个新特征,即孢子囊内存在穿孔,孔与孢子囊的空心柱相连。这个特征被认为是有孔虫目(Foraminispora)的一种突触形态,这里提出了一个新的属,以适应有孔虫(Porothelium rugosum)。Furtadoa被认为可以容纳单元化环境下的物种:F. biseptata、F. brasiliensis和F. corneri。分子系统发育分析证实,这两个属被归为强烈支持的不同谱系的黑霉属。进化枝。
