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 (ITS1-5.8S-ITS2 = 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.
