Two new records of Tricholoma species from Pakistan based on morphological features and phylogenetic analysis

Two species of Tricholoma , T. bonii and T. triste , are reported as new records for Pakistan. Phylogenetic analysis based on the nuclear ribosomal internal transcribed spacer (nrITS) region clustered the Pakistani collections with T. bonii and T. triste sequences from previous worldwide collections. Detailed descriptions of macro- and microcharacters, habitat, general distribution, and diagnostic features are presented.
