Lepista irina (Fr.) H. E. Bigelow is a common edible mushroom belonging to the Tricholomataceae family (Agaricales; Basidiomycota). This species has been recorded for the first time in Pakistan as a result of an extensive biodiversity assessment of the mushrooms of the Shangla region of Khyber Pakhtunkhwa. We present an in-depth phylogenetic analysis of the nrDNA ITS sequences along with micro- and macro-morphological descriptions for the authentic taxonomic placement of this species.
