Inocybe kohistanensis, a new species, is described from Swat, Khyber Pakhtunkhwa, Pakistan, on the basis of morphological characters as well as molecular phylogenetic analyses. The new species is characterized by a fibrillose reddish brown pileus, pruinose stipe with a prominent marginate bulb, and nodular spores. Sequences from the internal transcribed spacer region suggest that I. kohistanensis is distinct from all other Inocybe species sampled. | Turkish Journal of Botany Turk J Bot (2016) 40: 312-318 © TÜBİTAK doi: Research Article Inocybe kohistanensis, a new species from Swat, Pakistan 1, 2 2 1 Sana JABEEN *, Ishtiaq AHMAD , Abdur RASHID , Abdul Nasir KHALID Department of Botany, University of the Punjab, Quaid-e-Azam Campus, Lahore, Pakistan 2 Centre of Plant Biodiversity and Conservation, University of Peshawar, Peshawar, Pakistan 1 Received: Accepted/Published Online: Final Version: Abstract: Inocybe kohistanensis, a new species, is described from Swat, Khyber Pakhtunkhwa, Pakistan, on the basis of morphological characters as well as molecular phylogenetic analyses.

Key words: Dry temperate forest, internal transcribed spacer, marginate bulb 1. Introduction Inocybe (Fr.) Fr. (Agaricales, Inocybaceae) is a large genus with an estimated 735 species (Kirk et al., 2008; Kobayashi, 2009; Matheny et al., 2009; Kobayashi and Onishi, 2010; Kropp et al., 2010; Bougher and Matheny, 2011; Bougher et al., 2012; Kokkonen and Vauras, 2012; Matheny et al., 2012; Fan and Bau, 2013; Braaten et al., 2014; Fan and Bau, 2014; Esteve-Raventós et al., 2015) and the number will considerably increase as collections from unexplored regions are studied. Species of the genus are commonly found in temperate areas (Singer, 1962; Matheny et al., 2003) while occurring to a lesser extent throughout the tropics (Horak, 1979; Singer et al., 1983; Buyck and Eyssartier, 1999; Matheny et al., 2003). They are widespread and are found in all major biogeographic regions. Records have been found from Africa (Buyck and Eyssartier, 1999), Australia (Bougher and Matheny,
