Fungi are rich in complexes of cryptic species that need a combination of different approaches to be delimited, including genomic information. Beauveria (Cordycipitaceae, Hypocreales) is a well-known genus of entomopathogenic fungi, used as a biocontrol agent. In this study we present a polyphasic taxonomy regarding two widely distributed complexes of Beauveria: B. asiatica and B. bassiana 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 B. asiatica and among three clades in B. bassiana, 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 B. bassiana while conidial length was significantly different among clades within B. asiatica. The secondary metabolite profiles obtained by liquid chromatography-mass spectrometry (LC-MS) allowed a distinction between B. asiatica and B. bassiana, but not between the clades therein. Based on these genomic, morphological, chemical data, we proposed a clade of B. asiatica as a new species, named B. thailandica, and two clades of B. bassiana to respectively represent B. namnaoensis and B. neobassiana spp. nov. Such closely related but divergent species with different host ranges have potential to elucidate the evolution of host specificity, with potential biocontrol application.

真菌中存在丰富的隐性物种群,需要结合不同的方法(包括基因组信息)才能对其进行划分。Beauveria(虫草科,Hypocreales)是一个著名的昆虫病原真菌属,被用作生物控制剂。在本研究中,我们对两种广泛分布的蒲公英复合菌进行了多相分类:B. asiatica 和 B. bassiana s.lat.以前在这两个类群中检测到的一些基因群通过群体基因组学得到了证实或融合。在 B. asiatica 的两个支系之间和 B. bassiana 的三个支系之间发现了高度的分化,支持将它们细分为不同的物种。形态学检查的重点是噬菌体和分生孢子的宽度和长度,结果表明 B. bassiana 内部各支系之间没有差异,而 B. asiatica 内部各支系之间的分生孢子长度有显著差异。通过液相色谱-质谱法(LC-MS)获得的次生代谢物图谱可以区分 B. asiatica 和 B. bassiana,但不能区分其中的支系。根据这些基因组、形态学和化学数据,我们提议将 B. asiatica 的一个支系作为一个新种,命名为 B. thailandica,并将 B. bassiana 的两个支系分别代表 B. namnaoensis 和 B. neobassiana spp.这些亲缘关系密切但寄主范围不同的物种有可能阐明寄主特异性的进化,具有潜在的生物防治应用价值。引用:Kobmoo N, Arnamnart N, Pootakham W, et al.利用全基因组测序、形态计量学和化学分析对亚西亚真菌(Beauveria asiatica)和巴西真菌(B. bassiana)物种复合体进行综合分类。Persoonia 47: 136-150. https://doi.org/10.3767/persoonia.2021.47.04.

Several plant pathogenic Parastagonospora species have been identified infecting wheat and other cereals over the past 50 years. As new lineages were discovered, naming conventions grew unwieldy and the relationships with previously recognized species remained unclear. We used genome sequencing to clarify relationships among these species and provided new names for most of these species. Six of the nine described Parastagonospora species were recovered from wheat, with five of these species coming from Iran. Genome sequences revealed that three strains thought to be hybrids between P. nodorum and P. pseudonodorum were not actually hybrids, but rather represented rare gene introgressions between those species. Our data are consistent with the hypothesis that P. nodorum originated as a pathogen of wild grasses in the Fertile Crescent, then emerged as a wheat pathogen via host-tracking during the domestication of wheat in the same region. The discovery of a diverse array of Parastagonospora species infecting wheat in Iran suggests that new wheat pathogens could emerge from this region in the future.

在过去的 50 年中,已经发现了多个感染小麦和其他谷物的植物致病性副伞孢属(Parastagonospora)物种。随着新品系的发现,命名规则变得越来越晦涩难懂,而且与之前确认的物种之间的关系仍不明确。我们利用基因组测序澄清了这些物种之间的关系,并为其中大多数物种提供了新名称。在已描述的 9 个 Parastagonospora 物种中,有 6 个是从小麦中发现的,其中 5 个来自伊朗。基因组序列显示,被认为是 P. nodorum 和 P. pseudonodorum 之间杂交种的三个菌株实际上并不是杂交种,而是这些物种之间罕见的基因导入。我们的数据与以下假设一致,即 P. nodorum 起源于新月沃地的一种野生禾本科植物病原体,然后在同一地区的小麦驯化过程中通过宿主追踪成为小麦病原体。在伊朗发现的感染小麦的 Parastagonospora 种类繁多,这表明未来该地区可能会出现新的小麦病原体。引用:Croll D, Crous PW, Pereira D, et al.基因组规模的系统发育揭示了感染驯化和野生禾本科植物的 Parastagonospora 物种之间的关系。Persoonia 46: 116-128. https://doi.org/10.3767/persoonia.2021.46.04.

Novel collophorina-like genera and species from Prunus trees and vineyards in Germany. 来自德国梅树和葡萄园的新型胶孢菌属和种。

Strains with a yeast-like appearance were frequently collected in two surveys on the biodiversity of fungi in Germany, either associated with necroses in wood of Prunus trees in orchards in Saxony, Lower Saxony and Baden-Württemberg or captured in spore traps mounted on grapevine shoots in a vineyard in Rhineland-Palatinate. The morphology of the strains was reminiscent of the genus Collophorina: all strains produced aseptate conidia on integrated conidiogenous cells directly on hyphae, on discrete phialides, adelophialides and by microcyclic conidiation, while in some strains additionally endoconidia or conidia in conidiomata were observed. Blastn searches with the ITS region placed the strains in the Leotiomycetes close to Collophorina spp. Analyses based on morphological and multi-locus sequence data (LSU, ITS, EF-1α, GAPDH) revealed that the 152 isolates from wood of Prunus spp. belong to five species including C. paarla, C. africana and three new species. A further ten isolates from spore traps belonged to seven new species, of which one was isolated from Prunus wood as well. However, a comparison with both LSU and ITS sequence data of these collophorina-like species with reference sequences from further Leotiomycetes revealed the genus Collophorina to be polyphyletic and the strains to pertain to several genera within the Phacidiales. Collophorina paarla and C. euphorbiae are transferred to the newly erected genera Pallidophorina and Ramoconidiophora, respectively. The new genera Capturomyces, Variabilispora and Vexillomyces are erected to accommodate five new species isolated from spore traps. In total nine species were recognised as new to science and described as Collophorina badensis, C. germanica, C. neorubra, Capturomyces funiculosus, Ca. luteus, Tympanis inflata, Variabilispora flava, Vexillomyces palatinus and V. verruculosus.

在德国进行的两次真菌生物多样性调查中,经常收集到外观类似酵母菌的菌株,这些菌株要么与萨克森州、下萨克森州和巴登-符腾堡州果园中梅树木质部的坏死有关,要么是在莱茵兰-法尔茨州葡萄园中安装在葡萄树嫩枝上的孢子捕获器中捕获的。这些菌株的形态与柯洛佛尔菌属(Collophorina)相似:所有菌株的无菌分生孢子都直接长在菌丝上的整合分生孢子器细胞上、离散的分生孢子器细胞上、腺分生孢子器细胞上以及微环状分生孢子器上,在一些菌株中还能观察到内生分生孢子器或分生孢子器中的分生孢子。基于形态学和多焦点序列数据(LSU、ITS、EF-1α、GAPDH)的分析表明,从李属植物木材中分离的 152 个菌株属于 5 个物种,包括 C. paarla、C. africana 和 3 个新物种。从孢子捕获器中分离出的另外 10 个分离物属于 7 个新种,其中 1 个也是从梅树木材中分离出来的。然而,将这些胶孢菌属同类物种的 LSU 和 ITS 序列数据与来自其他乐彩网菌属的参考序列进行比较后发现,胶孢菌属具有多型性,这些菌株属于 Phacidiales 中的多个属。Collophorina paarla 和 C. euphorbiae 分别归入新建立的 Pallidophorina 属和 Ramoconidiophora 属。新建立的 Capturomyces 属、Variabilispora 属和 Vexillomyces 属容纳了从孢子捕获器中分离出的 5 个新种。总共有 9 个物种被认为是科学界的新物种,并被描述为 Collophorina badensis、C. germanica、C. neorubra、Capturomyces funiculosus、Ca. luteus、Tympanis inflata、Variabilispora flava、Vexillomyces palatinus 和 V. verruculosus。

Dieback and decline pathogens of olive trees in South Africa. 南非橄榄树的枯死和衰退病原体。
IF 9.1 1区 生物学 Q1 MYCOLOGY Pub Date : 2020-12-01 Epub Date: 2020-10-29 DOI: 10.3767/persoonia.2020.45.08

Trunk disease fungal pathogens reduce olive production globally by causing cankers, dieback, and other decline-related symptoms on olive trees. Very few fungi have been reported in association with olive dieback and decline in South Africa. Many of the fungal species reported from symptomatic olive trees in other countries have broad host ranges and are known to occur on other woody host plants in the Western Cape province, the main olive production region of South Africa. This survey investigated the diversity of fungi and symptoms associated with olive dieback and decline in South Africa. Isolations were made from internal wood symptoms of 145 European and 42 wild olive trees sampled in 10 and 9 districts, respectively. A total of 99 taxa were identified among 440 fungal isolates using combinations of morphological and molecular techniques. A new species of Pseudophaeomoniella, P. globosa, had the highest incidence, being recovered from 42.8 % of European and 54.8 % of wild olive samples. This species was recovered from 9 of the 10 districts where European olive trees were sampled and from all districts where wild olive trees were sampled. Members of the Phaeomoniellales (mainly P. globosa) were the most prevalent fungi in five of the seven symptom types considered, the only exceptions being twig dieback, where members of the Botryosphaeriaceae were more common, and soft/white rot where only Basidiomycota were recovered. Several of the species identified are known as pathogens of olives or other woody crops either in South Africa or elsewhere in the world, including species of Neofusicoccum, Phaeoacremonium, and Pleurostoma richardsiae. However, 81 of the 99 taxa identified have not previously been recorded on olive trees and have unknown interactions with this host. These taxa include one new genus and several putative new species, of which four are formally described as Celerioriella umnquma sp. nov., Pseudophaeomoniella globosa sp. nov., Vredendaliella oleae gen. & sp. nov., and Xenocylindrosporium margaritarum sp. nov.

树干病真菌病原体通过在橄榄树上引起溃疡病、枯死和其他衰退相关症状,在全球范围内减少橄榄产量。在南非,很少有真菌与橄榄树枯死和衰退有关。据报道,在其他国家有症状的橄榄树上发现的许多真菌种类具有广泛的寄主范围,并且已知在南非主要橄榄产区西开普省的其他木本寄主植物上也存在。这项调查调查了真菌的多样性和与南非橄榄枯萎和衰退相关的症状。分别从10个和9个地区取样的145棵欧洲橄榄树和42棵野生橄榄树的木材内部症状进行了分离。利用形态学和分子生物学相结合的方法,从440株真菌中鉴定出99个分类群。在欧洲橄榄和野生橄榄样品中,分别有42.8%和54.8%的检出率为最高,为球状假单胞菌新种。该物种在采集欧洲橄榄树样本的10个地区中的9个地区以及采集野生橄榄树样本的所有地区均有恢复。在考虑的七种症状类型中,Phaeomoniellales(主要是P. globosa)的成员是最普遍的真菌,唯一的例外是树枝枯枝,其中Botryosphaeriaceae的成员更常见,以及软腐/白腐,其中只有担子菌被恢复。在南非或世界其他地方,已经鉴定出的几个物种是橄榄或其他木本作物的病原体,包括Neofusicoccum、Phaeoacremonium和Pleurostoma richardsiae。然而,鉴定的99个分类群中有81个以前没有在橄榄树上记录过,并且与这个宿主有未知的相互作用。这些分类群包括1个新属和若干推测新种,其中4个被正式描述为:unnquma Celerioriella sp. nov.、Pseudophaeomoniella globosa sp. nov.、Vredendaliella oleae gen. & sp. nov.和Xenocylindrosporium margararum sp. nov.。

Gymnosporangium species (Pucciniaceae, Pucciniales, Basidiomycota) are the causal agents of cedar-apple rust diseases, which can lead to significant economic losses to apple cultivars. Currently, the genus contains 17 described species that alternate between spermogonial/aecial stages on Malus species and telial stages on Juniperus or Chamaecyparis species, although these have yet to receive a modern systematic treatment. Furthermore, prior studies have shown that Gymnosporangium does not belong to the Pucciniaceae sensu stricto (s.str.), nor is it allied to any currently defined rust family. In this study we examine the phylogenetic placement of the genus Gymnosporangium. We also delineate interspecific boundaries of the Gymnosporangium species on Malus based on phylogenies inferred from concatenated data of rDNA SSU, ITS and LSU and the holomorphic morphology of the entire life cycle. Based on these results, we propose a new family, Gymnosporangiaceae, to accommodate the genus Gymnosporangium, and recognize 22 Gymnosporangium species parasitic on Malus species, of which G. lachrymiforme, G. shennongjiaense, G. spinulosum, G. tiankengense and G. kanas are new. Typification of G. asiaticum, G. fenzelianum, G. juniperi-virginianae, G. libocedri, G. nelsonii, G. nidus-avis and G. yamadae are proposed to stabilize the use of names. Morphological and molecular data from type materials of 14 Gymnosporangium species are provided.

裸子孢子菌属(puccininiaceae, puccininiales, Basidiomycota)是雪松苹果锈病的病原菌,对苹果品种造成重大经济损失。目前,该属包含17个已描述的物种,它们在苹果物种的精子/非精子阶段和杜松或Chamaecyparis物种的端部阶段之间交替,尽管这些物种尚未得到现代系统的处理。此外,先前的研究表明,裸子孢属(Gymnosporangium)不属于puccininiaceae sensu stricto (s.str.),也不属于任何目前定义的锈病科。在本研究中,我们研究了裸子属植物的系统发育位置。基于rDNA SSU、ITS和LSU数据的系统发育以及整个生命周期的全胚形态,我们还划定了苹果属裸子孢子属的种间边界。在此基础上,我们提出了一个新的科——Gymnosporangiaceae,以适应Gymnosporangium属,并鉴定了寄生于苹果属的22种Gymnosporangium,其中G. lachrymiformme、G. shen农嘉ense、G. spinulosum、G. tiankengense和G. kanas为新属。为了稳定名称的使用,建议将asiaticum、G. fenzelianum、G. juniperii -virginianae、G. libocedri、G. nelsonii、G. nidus-avis和G. yamadae进行分类。本文提供了14种裸子属植物的形态和分子资料。最后,给出了苹果上各裸子孢子属植物的形态特征、寄主交替和地理分布资料。

The genus Calonectria includes many important plant pathogens with a wide global distribution. In order to better understand the reproductive biology of these fungi, we characterised the structure of the mating type locus and flanking genes using the genome sequences for seven Calonectria species. Primers to amplify the mating type genes in other species were also developed. PCR amplification of the mating type genes and multi-gene phylogenetic analyses were used to investigate the mating strategies and evolution of mating type in a collection of 70 Calonectria species residing in 10 Calonectria species complexes. Results showed that the organisation of the MAT locus and flanking genes is conserved. In heterothallic species, a novel MAT gene, MAT1-2-12 was identified in the MAT1-2 idiomorph; the MAT1-1 idiomorph, in most cases, contained the MAT1-1-3 gene. Neither MAT1-1-3 nor MAT1-2-12 was found in homothallic Calonectria (Ca.) hongkongensis, Ca. lateralis, Ca. pseudoturangicola and Ca. turangicola. Four different homothallic MAT locus gene arrangements were observed. Ancestral state reconstruction analysis provided evidence that the homothallic state was basal in Calonectria and this evolved from a heterothallic ancestor.

Calonectria属包括许多重要的植物病原体,具有广泛的全球分布。为了更好地了解这些真菌的生殖生物学,我们利用7种Calonectria的基因组序列对交配型位点和侧翼基因的结构进行了表征。在其他物种中扩增交配型基因的引物也被开发出来。采用PCR扩增和多基因系统发育分析的方法,对10个卡罗尼卡种复合体中70个卡罗尼卡种的交配策略和交配类型的进化进行了研究。结果表明,MAT位点和侧翼基因的组织结构是保守的。在异thalic物种中,MAT1-2-12是一个新的MAT基因;大多数情况下,MAT1-1特型含有MAT1-1-3基因。MAT1-1-3和MAT1-2-12均未在同属植物calonectriia (Ca.) hongkongensis、Ca. lateralis、Ca. pseudoturangicola和Ca. turangicola中发现。观察到四种不同的同源MAT位点基因排列。祖先状态重建分析提供了证据,表明Calonectria的同thalic状态是基础的,并且是从异thalic祖先进化而来的。

Fungal associates of an invasive pine-infesting bark beetle, Dendroctonus valens, including seven new Ophiostomatalean fungi. 一种入侵松树的树皮甲虫的真菌伴生物,包括7种新的蛇口真菌。
IF 9.1 1区 生物学 Q1 MYCOLOGY Pub Date : 2020-12-01 Epub Date: 2020-07-22 DOI: 10.3767/persoonia.2020.45.07

The red turpentine beetle (RTB; Dendroctonus valens) is a bark beetle that is native to Central and North America. This insect is well-known to live in association with a large number of Ophiostomatalean fungi. The beetle is considered a minor pest in its native range, but has killed millions of indigenous pine trees in China after its appearance in that country in the late 1990s. In order to increase the base of knowledge regarding the RTB and its symbionts, surveys of the beetle's fungal associates were initially undertaken in China, and in a subsequent study in its native range in North America. A total of 30 Ophiostomatalean species that included several undescribed taxa, were identified in these surveys. In the present study, seven of the undescribed taxa collected during the surveys were further characterised based on their morphological characteristics and multi-gene phylogenies. We proceeded to describe five of these as novel Leptographium spp. and two as new species of Ophiostoma. Four of the Leptographium spp. resided in the G. galeiformis-species complex, while one formed part of the L. olivaceum-species complex. One Ophiostoma sp. was a member of the O. ips-species complex, while the only new species from China was closely related to O. floccosum. Two of the previously undescribed taxa from North America were shown to be congeneric with L. terebrantis, implying that this species was most often isolated in association with the RTB in North America. The undescribed taxon from North America was identified as O. ips, and like L. terebrantis, this species was also not recognized during the initial North American survey. Resolving the identities of these taxa provides essential baseline information to better understand the movement of fungal pathogens with this beetle. This then enhances our ability to accurately assess and predict the risks of invasions by these and related fungi.

红松节油甲虫(RTB;是一种树皮甲虫,原产于中美洲和北美洲。众所周知,这种昆虫与大量的蛇口真菌生活在一起。这种甲虫在其本土范围内被认为是一种小害虫,但自上世纪90年代末出现在中国以来,已经杀死了数百万棵本土松树。为了增加对这种甲虫及其共生体的知识基础,我们首先在中国开展了对这种甲虫的真菌类群的调查,随后在其北美原产地开展了研究。在这些调查中,共鉴定出30种蛇口动物,其中包括一些未描述的分类群。在本研究中,基于形态学特征和多基因系统发育,对调查中收集到的7个未描述类群进行了进一步的表征。我们接着将其中的5种描述为新种Leptographium sp ., 2种描述为新种Ophiostoma。4个Leptographium属属于G. galeiformis-种复合体,1个属于L. olivaceum-种复合体。其中1种为O. ips-种复合体的成员,唯一来自中国的新种与O. flocosum关系密切。其中2个来自北美的未被描述的分类群与L. terebrantis是同源的,这意味着该物种通常与北美的RTB有关联。未描述的北美分类群被鉴定为O. ips,与L. terebrantis一样,该物种在最初的北美调查中也未被发现。解决这些分类群的身份提供了必要的基线信息,以更好地了解真菌病原体与这种甲虫的运动。这就提高了我们准确评估和预测这些真菌和相关真菌入侵风险的能力。

Cytospora (Diaporthales) in China. 标题中国的胞孢子目。
IF 9.1 1区 生物学 Q1 MYCOLOGY Pub Date : 2020-12-01 Epub Date: 2019-06-18 DOI: 10.3767/persoonia.2020.45.01

Members of the genus Cytospora are often reported as endophytes, saprobes or phytopathogens, primarily causing canker diseases of woody host plants. They occur on a wide range of hosts and have a worldwide distribution. Although several species have in the past been reported from China, the vast majority are not known from culture or DNA phylogeny. The primary aim of the present study was thus to clarify the taxonomy and phylogeny of a large collection of Cytospora species associated with diverse hosts in China. Cytospora spp. were collected in northeast, northwest, north and southwest China, indicating that the cold and dry environments favour these fungi. In this paper, we provide an assessment of 52 Cytospora spp. in China, focussing on 40 species represented by 88 isolates from 28 host genera. Based on a combination of morphology and a six-locus phylogeny (ITS, LSU, act1, rpb2, tef1-α and tub2), 13 new species and one new combination are introduced. The majority of the species investigated here appear to be host-specific, although further collections and pathogenicity studies will be required to confirm this conclusion.

胞孢子菌属的成员经常被报道为内生菌、腐殖菌或植物病原体,主要引起木本寄主植物的溃疡病。它们发生在广泛的宿主上,并在世界范围内分布。虽然过去在中国报道过一些物种,但绝大多数都没有从培养或DNA系统发育中了解。因此,本研究的主要目的是澄清与中国不同寄主相关的大量胞孢子属物种的分类和系统发育。在东北、西北、华北和西南地区采集到胞孢子菌,表明寒冷干燥的环境有利于这些真菌的生长。本文对中国52种胞孢子虫进行了鉴定,重点分析了来自28个寄主属的88株40种胞孢子虫。基于形态学组合和6位点系统发育(ITS、LSU、act1、rpb2、tef1-α和tub2),共获得13个新种和1个新组合。这里调查的大多数物种似乎是宿主特异性的,尽管需要进一步的收集和致病性研究来证实这一结论。

Specimens of Nectria spp. and Nectriella rufofusca were obtained from the fungarium of Pier Andrea Saccardo, and investigated via a morphological and molecular approach based on MiSeq technology. ITS1 and ITS2 sequences were successfully obtained from 24 specimens identified as 'Nectria' sensu Saccardo (including 20 types) and from the type specimen of Nectriella rufofusca. For Nectria ambigua, N. radians and N. tjibodensis only the ITS1 sequence was recovered. On the basis of morphological and molecular analyses new nomenclatural combinations for Nectria albofimbriata, N. ambigua, N. ambigua var. pallens, N. granuligera, N. peziza subsp. reyesiana, N. radians, N. squamuligera, N. tjibodensis and new synonymies for N. congesta, N. flageoletiana, N. phyllostachydis, N. sordescens and N. tjibodensis var. crebrior are proposed. Furthermore, the current classification is confirmed for Nectria coronata, N. cyanostoma, N. dolichospora, N. illudens, N. leucotricha, N. mantuana, N. raripila and Nectriella rufofusca. This is the first time that these more than 100-yr-old specimens are subjected to molecular analysis, thereby providing important new DNA sequence data authentic for these names.

摘要利用MiSeq技术,从意大利沙卡多码头(Pier Andrea Saccardo)的真菌场中获得了nectriia spp.和rufofusca Nectriella的标本,并进行了形态学和分子生物学的研究。成功地从24个被鉴定为“nectriia”sensu Saccardo的标本(包括20个类型)和rufofusca的模式标本中获得了ITS1和ITS2序列。对于双歧黑蝇、弧度黑蝇和黑蝇,只恢复了ITS1序列。在形态学和分子生物学分析的基础上,建立了红木网蝗、双歧网蝗、双歧网蝗变种黄斑网蝗、细粒网蝗和紫斑网蝗的新命名组合。提出了reyesiana, radians, squamuligera, njibodensis和congesta, nflageoletiana, phyllostachydis, nsordescens和njibodensis var. crebris的新同义词。此外,冠状nectriia coronata、cyanostoma、N. dolichospora、N. illudens、N. leucotricha、N. mantuana、N. raripila和rufofusca的分类也得到了确认。这是第一次对这些100多年前的标本进行分子分析,从而为这些名字提供了重要的新的DNA序列数据。
