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>
