Aligned 5-locus dataset of Inocybe sect. Rimosae s.s. subclade A

This is the aligned, concatenated ITS1–5.8S–ITS2–nrLSU–mtSSU dataset of <i>Inocybe </i>sect. <i>Rimosae </i>s.s. subclade A, used for molecular phylogenetic reconstruction with IQ-TREE under partitioned models.<br><br> <b>New species of <i>Inocybe</i> sect. <i>Rimosae</i> from Pakistan revealed by multi-locus phylogenetic reconstruction</b><b></b> Malka Saba, Danny Haelewaters, Donald H. Pfister, Abdul Nasir Khalid<br> <b>Abstract</b> During fungal surveys between 2012 and 2014 in pine-dominated forests of the western Himalayas in Pakistan, several collections of <i>Inocybe</i> (Agaricales, Inocybaceae) were made. These were documented based on morphological and molecular data. During this work, three new species came to light, which are here formally described as <i>Inocybe brunneoumbonata</i>, <em>I. pinophila,</em> and <em>I. triacicularis</em>. These species are part of sect. <i>Rimosae</i> s.s. and belong to or are closely related to <i>Rimosae</i> s.s. subclade A. Macro- and micro-morphological descriptions, illustrations, and molecular phylogenetic reconstructions of the studied taxa are provided. The new species are differentiated from their close relatives by basidiospore size and coloration of basidiomata. Molecular phylogenetic relationships are inferred using ITS (ITS1–5.8S–ITS2), nrLSU, and mtSSU sequence data. All three newly described taxa likely share an ectomycorrhizal association with trees in the genus <i>Pinus</i>. <b>Keywords</b> 3 new taxa, ectomycorrhizal fungi, Inocybaceae, Pakistan, phylogeny, <i>Pinus roxburghii</i>, taxonomy<br>

本数据集为丝盖伞属（*Inocybe*）裂盖组（sect. Rimosae）狭义类群（s.s.）A亚分支的比对拼接型ITS1–5.8S–ITS2（内部转录间隔区1–5.8S–内部转录间隔区2）、nrLSU（核核糖体大亚基，nuclear Large Subunit rRNA）及mtSSU（线粒体核糖体小亚基，mitochondrial Small Subunit rRNA）序列数据集，用于基于分区模型的IQ-TREE分子系统发育重建。

**摘要** 2012年至2014年，研究团队在巴基斯坦西喜马拉雅地区以松树为优势种的森林中开展真菌调查期间，采集到多份丝盖伞属（*Inocybe*，伞菌目，丝盖伞科）标本。所有标本均基于形态学与分子数据进行完整记录。本研究共发现3个新物种，正式描述为棕顶丝盖伞（*Inocybe brunneoumbonata*）、松生丝盖伞（*I. pinophila*）与三孢丝盖伞（*I. triacicularis*）。这些物种隶属于裂盖组狭义类群，属于或与裂盖组狭义类群A亚分支亲缘关系密切。文中提供了研究类群的宏观、微观形态描述、形态图解以及分子系统发育重建结果。3个新物种可通过担孢子大小与子实体色泽与其近缘类群相区分。本研究基于ITS（ITS1–5.8S–ITS2）、核核糖体大亚基（nrLSU）及线粒体核糖体小亚基（mtSSU）序列数据，推断了研究类群的分子系统发育关系。3个新描述的分类单元大概率与松属（*Pinus*）植物形成外生菌根共生关系。
