From 2000 to 2020, mycological studies in China has achieved encouraging progress in several aspects, such as discovery of new species, construction of new taxonomic schemes for important groups, biodiversity conservation and bio-resource exploitation. In this paper, the research progress of newly published fungal names in China, especially those from Chinese scholars are statistically summarized and presented based on the data retrieved from Index Fungorum, Fungal Names and MycoBank. The result shows that the number of Chinese scholars, and their research outputs have increased greatly in the new century, together with the increasing contribution to the world taxonomy of fungi. At least 9 430 new fungal names, including 7 120 new taxa (i.e. 3 new classes, 24 new orders, 88 new families, 4 new subfamilies, 492 new genera, 3 new subgenera, 23 new sections and subsections, 6 404 new species and 79 new intraspecific taxa), 1 868 new combinations, 61 new revised names and 381 other new names, were published by 1 491 Chinese scholars in 4 029 articles and 36 monographs, accounting for ca. 1/7 of all names published worldwide. These new fungal names belonged to 11 phyla, 43 classes, 173 orders, 525 families and 1 997 genera, among which ascomycetes and basidiomycetes have received more attentions. Most new fungal species were discovered from southern China, while Yunnan is the most important source of new discoveries accounting for ca. 1/4 of total in China.

新世纪以来,中国菌物学研究飞速发展,取得了令人瞩目的成就。在系统分类学方面,我国学者对担子菌门、“酵母菌”、蘑菇目、牛肝菌目、多孔菌目、亚隔孢壳科,以及一些具有广泛经济重要性的属如木霉属、刺盘孢属、青霉属、曲霉属等类群的系统发育构建和分类系统更新做出了重要贡献,并描述了大量的新分类单元(Zeng et al. 2013;Zhao et al. 2013;Liu et al. 2014;Wang et al. 2014;Wu et al. 2014;Wang et al. 2015;Zhao et al. 2016;Chen et al. 2017;Chen & Zhuang 2017;Zhao et al. 2017;Wang et al. 2018;Cui et al. 2019;He et al. 2019;Hou et al. 2020)。信息库建设方面,中国学者自主创建的菌物名称注册信息库(Fungal Names,
在大数据时代,生物多样性数据库中蕴藏着大量具有重要价值的生物学与生态学信息,如物种名称的变化、分类地位的改变、命名人、物种地理分布、生境、采集年代和时间等。这些信息不仅能揭示地区性物种多样性、生物资源调查研究的广度和深度,也可反映分类学及其相关学科的发展态势。本研究通过收集菌物名称发表数据,开展深入挖掘与分析,总结21世纪中国学者发表菌物新分类单元的情况和中国的菌物新物种发现概况,从而揭示中国菌物分类学的发展趋势。
1 数据来源
本研究的数据来自世界菌物名称信息库Index Fungorum(
根据Index Fungorum中的“Authors of fungal names”数据集,从原始数据中遴选出中国学者参与发表的记录共9 430条,用以分析中国学者在新分类单元发表方面的情况和贡献。根据分类阶元和模式标本产地的信息,从原始数据中筛选出中国菌物新物种发表记录共5 458条,作为中国菌物新物种的发表情况的分析数据。
2 中国学者发表菌物新名称概况
2.1 在世界的总体贡献
对菌物名称发表数据进行整体分析,发现2000-2020年间有1 491位中国学者参与了新分类单元及新名称的发表,发表了各类型菌物新名称9 430个,占全世界命名作者总数的14.31%和新名称总数的14.04%。中国学者参与发表的菌物新分类单元有7 120个,包括新纲3个、新目24个、新科88个、新亚科4个、新属492个、新亚属3个、新组及新亚组23个、新种6 404个和新种下单元(亚种、变种和变型)79个。此外,还发表了新组合1 868个、新修订名称61个和其他名称(不合格、不合法和弃用名称)381个。对各个名称的命名作者进行统计,其中56.11%(5 291个)的名称由中国作者独立完成发表,43.89%(4 139个)的名称与外国人合作发表。不同等级的新名称,中外作者合作的情况也不尽相同。新纲、新目和新科等高阶分类阶元,80%以上由中外作者合作发表,而60%以上新种及种下单元的发表由中国作者独立完成(表1)。

2.3 研究类群
新世纪以来,中国学者的菌物研究类群涵盖真菌(true fungi)、卵菌(oomycetes)和黏菌(slime mold)3个类群,涉及11门43纲173目525科1 997属。根据中国菌物名录数据库(
以科为单位,对各个类群的研究情况进行分析,统计发现中国学者在近21年侧重于在大型木生真菌(刺革菌科和多孔菌科)、牛肝菌(牛肝菌科)、小型子囊菌(亚隔孢壳科、隔孢腔菌科、间座壳科、毛壳科)和伞菌(蘑菇科和红菇科)等类群开展研究(表3)。值得注意的是,中国学者发表的103个新属和709个新种在科等级的分类地位未定(Incertae sedis),占新属总数的1/5和新种总数的1/10,这说明菌物的高阶分类系统还远未澄清。

4 展望
21世纪以来,我国菌物分类学研究类群逐渐扩大、研究人员稳步增加,取得了丰硕的研究成果,在世界范围也做出了突出的贡献并得到广泛认可。展望下一个20年,菌物分类学仍有许多重大问题尚未解决。首先,我国尚未完成菌物资源的全面普查,仍有许多地区的菌物多样性和资源分布信息处于空白状态,亟需开展相应的研究工作。据保守估计,全球菌物物种多样性有220-380万种(Hawksworth & Lücking 2017),而目前仅发现了不到6%,其描述率为地球主要生物类群中最低,仍有大量菌物新物种有待发现。我国菌物多样性也十分丰富,初步估计有超过30万种(魏江春 2010),已有一些研究初步统计出我国已知菌物物种约为1.25-2.79万种之间(戴玉成和庄剑云 2010;Fang et al. 2018; The Biodiversity Committee of Chinese Academy of Sciences 2020),目前已发现的物种仅有4%-9%。再者,菌物资源的开发应用范围需进一步扩大。全世界已经广泛认可菌类是人类最佳饮食结构的组成部分之一,而研究表明多种菌物具有多糖、核苷、微量元素等多种有益成分,可用于免疫调节、抗病毒、抑肿瘤等功效。目前,中国已报道的食药用菌数量为世界最多,有2 026种,而可人工栽培的仅有100余种,仍有大量具有开发潜质的物种(Fang et al. 2018)。除此之外,菌物可在生态、工业、农业等多个领域发挥效用,在现有工作基础上,进一步拓宽应用范围可以更充分地发挥菌物资源的价值。我国菌物资源的保护工作仍处于起步状态,亟须全面展开。目前全国仅有吉林天佛指山国家级自然保护区对野生松口蘑资源进行了保护,对其他受威胁物种还未采取有效的保护政策和措施。在今后的工作中需要填补对菌物资源野外检测的空白,同时在政策制定、就地保护、离体保存、科学普及等全方面开展保护工作,以促进菌物资源的可持续利用。

Discovery of a large-scaled survey of Trichoderma in soil from China
,DOI:10.1038/s41598-017-07807-3 PMID:28831112 [本文引用: 1]
The first large-scaled survey of soil-inhabiting Trichoderma is conducted in 23 provinces of China. Twenty-three new species belonging to the green-ascospored clades are discovered. Their phylogenetic positions are determined by sequence analyses of the combined partial sequences of translation elongation factor 1-alpha and the second largest RNA polymerase subunit encoding genes. Morphology and culture characteristics are observed, described and illustrated in detail. Distinctions between the new species and their close relatives are compared and discussed. They are named as: T. aggregatum, T. alpinum, T. bannaense, T. breve, T. brevicrassum, T. byssinum, T. chlamydosporicum, T. concentricum, T. ganodermatis, T. hainanense, T. hengshanicum, T. hirsutum, T. hunanense, T. ingratum, T. liberatum, T. linzhiense, T. longisporum, T. polypori, T. pseudodensum, T. simplex, T. solum, T. undatipile and T. zayuense.

Numbers of fungal species hitherto known in China
,Publications dealing with Chinese fungal species were systematically investigated, and 2,849 new species, 129 new varieties and 5,260 new Chinese records have been reported during 1978 to 2010. “Sylloge Fungorum Sinicorum” was published in 1979, listed 6,737 species and 168 varieties based on the reports on Chinese fungal resource until 1973. So 14,846 species and 297 varieties have been found in mainland China by 2010. In addition, 2,122 fungal species were recorded in Hong Kong and 6,207 in Taiwan, among which around 800 and 400 species, respectively, were not found in mainland China so far. Until now there are 16,046 species and 297 varieties have been recorded in the Chinese territory. If 10% of them are the synonyms, the Chinese fungal species are around 14,700. Among them around 300 species are Chromista, 340 are Protoza, and 14,060 are Fungi.

The Colletotrichum gigasporum species complex
,DOI:10.3767/003158514X684447 URL [本文引用: 1]
In a preliminary analysis, 21 Colletotrichum strains with large conidia preserved in the CBS culture collection clustered with a recently described species, C. gigasporum, forming a clade distinct from other currently known Colletotrichum species complexes. Multi-locus phylogenetic analyses (ITS, ACT, TUB2, CHS-1, GAPDH) as well as each of the single-locus analyses resolved seven distinct species, one of them being C. gigasporum. Colletotrichum gigasporum and its close allies thus constitute a previously unknown species complex with shared morphological features. Five of the seven species accepted in the C. gigasporum species complex are described here as novel species, namely C. arxii, C. magnisporum, C. pseudomajus, C. radicis and C. vietnamense. A species represented by a single sterile strain, namely CBS 159.50, was not described as novel species, and is treated as Colletotrichum sp. CBS 159.50. Furthermore, C. thailandicum is reduced to synonymy with C. gigasporum.
Moniliellomycetes and Malasseziomycetes, two new classes in Ustilaginomycotina
,DOI:10.3767/003158514X682313 URL [本文引用: 1]
Ustilaginomycotina (Basidiomycota, Fungi) has been reclassified recently based on multiple gene sequence analyses. However, the phylogenetic placement of two yeast-like genera Malassezia and Moniliella in the subphylum remains unclear. Phylogenetic analyses using different algorithms based on the sequences of six genes, including the small subunit (18S) ribosomal DNA (rDNA), the large subunit (26S) rDNA D1/D2 domains, the internal transcribed spacer regions (ITS 1 and 2) including 5.8S rDNA, the two subunits of RNA polymerase II (RPB1 and RPB2) and the translation elongation factor 1-alpha (EF1-alpha), were performed to address their phylogenetic positions. Our analyses indicated that Malassezia and Moniliella represented two deeply rooted lineages within Ustilaginomycotina and have a sister relationship to both Ustilaginomycetes and Exobasidiomycetes. Those clades are described here as new classes, namely Moniliellomycetes with order Moniliellales, family Moniliellaceae, and genus Moniliella; and Malasseziomycetes with order Malasseziales, family Malasseziaceae, and genus Malassezia. Phenotypic differences support this classification suggesting widely different life styles among the mainly plant pathogenic Ustilaginomycotina.

Molecular phylogenetic analyses redefine seven major clades and reveal 22 new generic clades in the fungal family Boletaceae
,DOI:10.1007/s13225-014-0283-8 URL [本文引用: 1]
Mushrooms in the basidiomycete family Boletaceae are ecologically and economically very important. However, due to the morphological complexity and the limited phylogenetic information on the various species and genera of this fungal family, our understanding of its systematics and evolution remains rudimentary. In this study, DNA sequences of four genes (nrLSU, tef1-alpha, rpb1, and rpb2) were newly obtained from ca. 200 representative specimens of Boletaceae. Our phylogenetic analyses revealed seven major clades at the subfamily level, namely Austroboletoideae, Boletoideae, Chalciporoideae, Leccinoideae, Xerocomoideae, Zangioideae, and the Pulveroboletus Group. In addition, 59 genus-level clades were identified, of which 22 were uncovered for the first time. These 22 clades were mainly placed in Boletoideae and the Pulveroboletus Group. The results further indicated that the characters frequently used in the morphology-based taxonomy of Boletaceae, such as basidiospore ornamentation, the form of the basidioma, and the stuffed pores each had multiple origins within the family, suggesting that the use of such features for high-level classification of Boletaceae should be de-emphasized and combined with other characters.

The genus Phylloporus (Boletaceae, Boletales) from China: morphological and multilocus DNA sequence inference
,DOI:10.1007/s13225-012-0184-7 URL [本文引用: 1]
Species of the genus Phylloporus in China were investigated based on morphology and molecular phylogenetic analysis of a three-locus (nrLSU, ITS and tef-1a) DNA sequence dataset. Twenty-one phylogenetic species were recognized among the studied collections. Seven of them are described as new: P. brunneiceps, P. imbricatus, P. maculatus, P. pachycystidiatus, P. rubeolus, P. rubrosquamosus, and P. yunnanensis. In addition, four of them correspond with the previous morphology-based taxa: P. bellus, P. luxiensis, P. parvisporus, and P. rufescens. The remaining ten phylogenetic species were not described due to the paucity of the materials. A key to the Chinese morphologically recognizable taxa was provided. A preliminary biogeographical analysis showed that (1) Pylloporus species in East Asia and Southeast Asia are mostly closely related, (2) species pairs or closely related species of Phylloporus between East Asia and North/Central America are relatively common, and (3) the biogeographic relationship of Phylloporus between East Asia and Europe was supported by only a single species pair. Unexpectedly, no taxa common either to both Europe and East Asia, or to both East Asia and North/Central America, were uncovered. Clades look to have taxa from both sides of the Pacific and Europe/Asia though.
New species and phylogeny of Perenniporia based on morphological and molecular characters
,DOI:10.1007/s13225-012-0177-6 URL [本文引用: 1]
Three new resupinate, poroid, wood-inhabiting fungi, Perenniporia aridula, P. bannaensis and P. substraminea, are introduced on the basis of morphological and molecular characters. Molecular study based on sequence data from the ribosomal ITS and LSU regions supported the three new species' positions in Perenniporia s.s., and all of them formed monophyletic lineages with strong support (100 % BP, 1.00 BPP). Phylogenetic analysis revealed seven clades for the 31 species of Perenniporia s.l. used in this study. Among them, Perenniporiella clustered with Perenniporia ochroleuca group, and then subsequently grouped with Abundisporus. In addition, the P. ochroleuca group, the P. vicina group, the P. martia group and P. subacida formed well supported monophyletic entities, which could be recognized as distinct genera, and they are not related to P. medulla-panis which belongs to Perenniporia s.s. clade. An identification key to 38 species of Perenniporia occurring in China is provided.
