Abstract

The new species Cortinarius himalayanus is described and illustrated based on specimens collected from the Himalayan moist temperate Abies pindrow forest of Pakistan. Macroscopically, this taxon is characterized by umbonate to subumbonate pilei, whose cuticle is reddish brown in the center and pale yellow towards the margins, yellowish brown lamellae, and cylindrical to clavate stipes showing yellowish brown to brown longitudinal-fibrillose veil remnants. Microscopically, C. himalayanus has ellipsoid to amygdaliform and finely verrucose basidiospores with an average size of 7.8 × 5 µm and avQ = 1.5. The new taxon is placed in Cortinarius subgenus Dermocybe based on a molecular phylogenetic analysis using ITS sequence data.
