Abstract
Rhodocollybia utrorensis sp. nov. is described from the Utror valley, Pakistan. It is characterized by a dull brown pileus with a low umbo and inrolled margin, adnate lamellae with wavy margin, presence of pleurocystidia and inamyloid basidiospores. Both morpho-anatomical features and phylogenetic analysis based on ITS nrDNA sequence indicate Rhodocollybia utrorensis is a new species. This is the first report of the genus Rhodocollybia from Pakistan.
