对于一个专着的基础上polythetic的概念，几千个标本馆标本，和几百个新鲜收集和培养的标本的炭层壳属和相关的Xylariaceae，来自世界各地的，进行了研究的形态特征，包括通过SEM，和化学HPLC配置文件，使用紫外可见和质谱检测。重点是热带材料，重要的是，古代标本，包括尽可能多的类型，被跟踪和研究，以审查早期的分类概念。D.选择Eschschscholtzii作为在热带分布最广的形态化学型的代表。本文描述了产于热带和南半球的炭层壳属6新种。沥青炭层壳（Daldinia aptagratum）复活，D. cudonia被认为是它的同义词。此外，下列二项组合是表型、异型、新型和/或选择型的：沥青炭层壳（Daldinia aptagratum）、沥青炭层壳D. caldariorum，黑腹拟步行虫D. clavata、D. cuprea、杜父鱼D. durissima、杜氏木霉D. eschscholtzii，黑腹叶蝉D. grandis、大叶蝉D. loculata和D. vernicosa。Annellosporium和Versiomyces被认为是炭层壳属的异名。在Daldinia中提出了许多新的同义词，并拒绝了一些以前发表的名称。共识别出炭层壳属47个分类群，并提供了检索表。它们的植物地理学、分布学和生态学，以及它们的次生代谢产物的重要性，也被讨论。修正了以往的属的定义。种的概念主要是基于形态和其他表型衍生的特征，因为尽管努力搜索，没有分子数据或文化的几个公认的物种可以获得。基于表型特征，炭层壳属被分成五个主要组。一些未命名但异常的标本被发现时状态不佳，因此没有被正式描述为新种。然而，他们详细说明，希望这将有助于发现新的材料在未来。基于5.8S/ITS nrDNA的初步分子系统学，包括迄今为止描述的所有现存的培养物的分类群的许多代表，被发现基本上与上述的属的分离，基于形态学和化学分类学的证据。在基于rDNA的系统发育树中，炭层壳属似乎与环木属和炭团属的成员明显不同;然而，主要来自热带的小属的代表（Entonaema，Phylacia，Ruwenzoria，Rhopalostroma，Thamnomalia）似乎是从炭层壳类的祖先进化而来的，并嵌套在炭层壳属的分支内。有趣的是，这些发现在很大程度上与化学分类学特征相关，特别是关于标记代谢物在其菌丝培养物中的分布。因此，目前的研究首次揭示了真菌次级代谢产物谱可以具有超越物种等级的分类学价值，甚至与系统发育数据相一致。andina sp. nov.，D. australissp. nov.，D.

For a monograph based on a polythetic concept, several thousands of herbarium specimens, and several hundreds of freshly collected and cultured specimens of Daldinia and allied Xylariaceae, originating from around the world, were studied for morphological traits, including by SEM, and chemically by HPLC profiles using UV-visible and mass spectrometric detection. Emphasis was given to tropical material, and importantly, ancient specimens, including as many types as possible, were tracked and studied to review earlier taxonomic concepts. An epitype of D. eschscholtzii was selected as representative of the morphochemotype that is most widely distributed in the tropics. Six new species of Daldinia from the tropics and the southern Hemisphere are described. Daldinia asphalatum is resurrected, and D. cudonia is regarded as its synonym. In addition, the following binomials are epi-, iso-, neo- and/or lectotypified: Daldinia asphalatum, D. caldariorum, D. clavata, D. cuprea, D. durissima, D. eschscholtzii, D. grandis, D. loculata, and D. vernicosa. Annellosporium and Versiomyces are regarded as synonyms of Daldinia. Many new synonymies in Daldinia are proposed, and some previously published names are rejected. In total, 47 taxa in Daldinia are recognised and a key is provided. Their biogeography, chorology, and ecology, as well as the importance of their secondary metabolites, are also discussed. The previous definition of the genus is emended. The species concept is based mainly on morphological and other phenotype-derived characters because, despite diligent search, no molecular data or cultures of several of the accepted species could be obtained. Daldinia is segregated into five major groups, based on phenotypic characteristics. Some unnamed but aberrant specimens were not found in good condition and are therefore not formally described as new species. However, they are illustrated in detail in a hope that this will facilitate the discovery of fresh material in future. A preliminary molecular phylogeny based on 5.8S/ITS nrDNA including numerous representatives of all hitherto described taxa for which cultures are extant, was found basically in agreement with the above mentioned segregation of the genus, based on morphological and chemotaxonomic evidence. In the rDNA based phylogenetic tree, Daldinia appears clearly distinct from members of the genera Annulohypoxylon and Hypoxylon; nevertheless, representatives of small genera of predominantly tropical origin (Entonaema, Phylacia, Ruwenzoria, Rhopalostroma, Thamnomyces) appear to have evolved from daldinioid ancestors and are nested inside the Daldinia clade. Interestingly, these findings correlate with chemotaxonomic characters to a great extent, especially regarding the distribution of marker metabolites in their mycelial cultures. Hence, the current study revealed for the first time that fungal secondary metabolite profiles can have taxonomic value beyond the species rank and even coincide with phylogenetic data.
