Abstract Cortinarius brunneocarpus var. microsporus is described and illustrated from coniferous forests of District Swat, Pakistan based on morphological characters and phylogenetic analyses of the nuclear rDNA internal transcribed spacer (ITS1-5.8SITS2 = ITS) region. It is morphologically well-supported by significantly smaller basidiospores which are moderately to strongly verrucose and with a suprahilar depression. The new variety has Eurasian distribution and is being reported from Pakistan, Norway and Estonia. Differences between the new variety and similar taxa are briefly discussed.

Introduction Cortinarius (Pers.) Gray is the largest genus of agaricoid fungi, comprising more than 2000 described species (Brandrud et al. 2018; Sesli and Liimatainen 2018; Soop et al. 2019). Species of Cortinarius have a worldwide distribution, forming ectomycorrhizal associations with some coniferous and broad-leaved trees (Brandrud et al. 1990; Niskanen 2008; Sesli and Liimatainen 2018; Soop et al. 2018). Based on the macromorphology, the genus Cortinarius has been traditionally divided into several subgenera and sections (Soop et al. 2019). However, based on additional micromorphological, chemical, and molecular evidence, most of these infrageneric levels were emended, combined, or divided. During the past two decades, many studies have been conducted to study the phylogeny of Cortinarius with a focus on infrageneric classification (Peintner et al. 2004; Harrower et al. 2011; Niskanen and Kytövuori 2012; Stensrud et al. 2014; Garnica et al. 2016; Soop et al. 2019).

Cortinarius still remain unresolved and for a robust phylogenetic support a dataset built on more loci is required (Frøslev et al. 2005; Soop et al. 2019). Cortinarius subg. Telamonia s.l., is the most speciose subgenus in Cortinarius, mostly described from the Northern Hemisphere (Garnica et al. 2016; Brandrud et al. 2018; Soop et al. 2019). It is considered as one of the most challenging lineages within Cortinarius (Brandrud et al. 2015; Liimatainen et al. 2015; Garrido-Benavent et al. 2019). In general, the Telamonia species have a dry, more or less hygrophanous non-viscid pileus and stipe and lack bright coloration (Moser 1983; Niskanen 2008). The subg. Telamonia is moderately well-documented in Europe and North America (Niskanen 2008; Niskanen et al. 2013; Brandrud et al. 2015; Soop et a
