Abstract

The phylogenetic position of several clitocyboid/pleurotoid/tricholomatoid genera previously considered incertae sedis is here resolved using an updated 6-gene dataset of Agaricales including newly sequenced lineages and more complete data from those already analyzed before. Results allowed to infer new phylogenetic relationships, and propose taxonomic novelties to accommodate them, including up to ten new families and a new suborder. Giacomia (for which a new species from China is here described) forms a monophyletic clade with Melanoleuca (Melanoleucaceae) nested inside suborder Pluteineae, together with the families Pluteaceae, Amanitaceae (including Leucocortinarius), Limnoperdaceae and Volvariellaceae. The recently described family Asproinocybaceae is shown to be a later synonym of Lyophyllaceae (which includes also Omphaliaster and Trichocybe) within suborder Tricholomatineae. The families Biannulariaceae, Callistosporiaceae, Clitocybaceae, Fayodiaceae, Macrocystidiaceae (which includes Pseudoclitopilus), Entolomataceae, Pseudoclitocybaceae (which includes Aspropaxillus), Omphalinaceae (Infundibulicybe and Omphalina) and the new families Paralepistaceae and Pseudoomphalinaceae belong also to Tricholomatineae. The delimitation of the suborder Pleurotineae (= Schizophyllineae) is discussed and revised, accepting five distinct families within it, viz. Pleurotaceae, Cyphellopsidaceae, Fistulinaceae, Resupinataceae and Schizophyllaceae. The recently proposed suborder Phyllotopsidineae (= Sarcomyxineae) is found to encompass the families Aphroditeolaceae, Pterulaceae, Phyllotopsidaceae, Radulomycetaceae, Sarcomyxaceae (which includes Tectella), and Stephanosporaceae, all of them unrelated to Pleurotaceae (suborder Pleurotineae) or Typhulaceae (suborder Typhulineae). The new family Xeromphalinaceae, encompassing the genera Xeromphalina and Heimiomyces, is proposed within Marasmiineae. The suborder Hygrophorineae is here reorganized into the families Hygrophoraceae, Cantharellulaceae, Cuphophyllaceae, Hygrocybaceae and Lichenomphaliaceae, to homogenize the taxonomic rank of the main clades inside all suborders of Agaricales. Finally, the genus Hygrophorocybe is shown to represent a distinct clade inside Cuphophyllaceae, and the new combination H. carolinensis is proposed.
姬松茸目中的家族事务:基于更新的 6 基因系统发育,对原生姬松茸类、褶姬松茸类和三姬松类群进行系统重组和分类
本文利用更新的姬蛙属 6 基因数据集(包括新测序的品系和以前已分析过的品系中更完整的数据),解决了以前认为不存在的几个栉水母属/褶水母属/三疣水母属的系统发育位置问题。研究结果推断出了新的系统发育关系,并提出了新的分类方法,包括多达 10 个新科和一个新的亚目。Giacomia(这里描述了中国的一个新种)与 Melanoleuca(Melanoleucaceae)形成了一个单系支系,嵌套在 Pluteineae 亚目内,同时嵌套的还有 Pluteaceae 科、Amanitaceae 科(包括 Leucocortinarius)、Limnoperdaceae 科和 Volvariellaceae 科。最近描述的 Asproinocybaceae 科被证明是 Lyophyllaceae(还包括 Omphaliaster 和 Trichocybe)在 Tricholomatineae 亚目中的后起异名。Biannulariaceae、Callistosporiaceae、Clitocybaceae、Fayodiaceae、Macrocystidiaceae(包括 Pseudoclitopilus)、Entolomataceae、Pseudoclitocybaceae(包括 Aspropaxillus)、Omphalinaceae(Infundibulicybe 和 Omphalina)以及新科 Paralepistaceae 和 Pseudoomphalinaceae 也属于 Tricholomatineae。对 Pleurotineae 亚目(= Schizophyllineae)的划分进行了讨论和修订,接受了其中的五个独立科,即 Pleurotaceae、Cyphellopsidaceae、Fistulinaceae、Resupinataceae 和 Schizophyllaceae。最近提出的Phyllotopsidineae(= Sarcomyxineae)亚目包括Aphroditeolaceae、Pterulaceae、Phyllotopsidaceae、Radulomycetaceae、Sarcomyxaceae(包括Tectella)和Stephanosporaceae科,它们都与Pleurotaceae(Pleurotineae亚目)或Typhulaceae(Typhulineae亚目)无关。新提出的 Xeromphalinaceae 科包括 Xeromphalina 属和 Heimiomyces 属,隶属于 Marasmiineae。姬松茸亚目(Hygrophorineae)在此重组为 Hygrophoraceae、Cantharellulaceae、Cuphophyllaceae、Hygrocybaceae 和 Lichenomphaliaceae 科,以统一姬松茸所有亚目内主要支系的分类等级。最后,Hygrophorocybe 属被证明代表濯缨草科(Cuphophyllaceae)中的一个独特支系,并提出了新的组合 H. carolinensis。

期刊介绍: The international journal Studies in Mycology focuses on advancing the understanding of filamentous fungi, yeasts, and various aspects of mycology. It publishes comprehensive systematic monographs as well as topical issues covering a wide range of subjects including biotechnology, ecology, molecular biology, pathology, and systematics. This Open-Access journal offers unrestricted access to its content. Each issue of Studies in Mycology consists of around 5 to 6 papers, either in the form of monographs or special focused topics. Unlike traditional length restrictions, the journal encourages submissions of manuscripts with a minimum of 50 A4 pages in print. This ensures a thorough exploration and presentation of the research findings, maximizing the depth of the published work.
