Abstract

Laccaria violaceotincta sp. nov. is described from Kerala State, India based on morphology and molecular phylogeny. All the collections of the species were made from a freshwater swamp forest predominantly composed of species of Myristica. The Maximum Likelihood (ML) analysis of sequence of the internal transcribed spacer (nrITS) of the ribosomal RNA gene clearly revealed its novelty as well as its position within the genus Laccaria. A taxonomic description, photographs of the basidiocarps and the micro-structures, comparisons with phenetically similar and phylogenetically related species and a phylogram depicting the placement of the new species are provided.
