Termitomyces are found associated with termites and show an exo-symbiotic relationship with termites. Both termites and Termitomyces are important in forest ecosystems for wood degradation. The morphological diversity of Termitomyces mushrooms as observed in Assam is high similar to other forest-rich regions of India. But the genetic diversity and species diversity from the region is not yet documented well. In the present study, DAMD and ISSR markers were applied for genetic diversity estimation and nrDNA ITS marker was applied for the phylogenetic study of the Termitomyces mushrooms collected from different localities of Assam. Besides, morphological characters were compared to the existing species monographs to identify the species. Based on morpho-molecular studies, the species identified are T. heimii, T. microcarpus, and T. eurrhizus. Five morphotypes of Termitomyces different from the existing species descriptions are recorded and are also sub-clustered distinctly and distantly in a phylogenetic tree generated based on nrDNA ITS sequences. The presence of novel species of Termitomyces is very much likely in the region which needs further taxonomic engagements to establish the neo species through valid publication.
