Abstract
This study outlines the biodiversity of mushrooms of India. It reveals the molecular biodiversity and divergence time estimation of basidiomycetes from Gujarat, India. A total of 267 mushrooms were collected from 10 locations across the state. 225 ITS sequences were generated belonging to 105 species, 59 genera and 29 families. Phylogenetic analysis of Agaricaceae reveals monophyletic clade of Podaxis differentiating it from Coprinus. Further, the ancient nature of Podaxis supports the hypothesis that gasteroid forms evolved from secotioid forms. Members of Polyporaceae appeared polyphyletic. Further, our results of a close phylogenetic relationship between Trametes and Lenziteslead us to propose that the genera Trametes may by enlarged to include Lenzites. The tricholomatoid clade shows a clear demarcation for Entolomataceae. However, Lyophyllaceae and Tricholomataceae could not be distinguished clearly. Distribution studies of the mushrooms showed omnipresence of Ganoderma and Schizophyllum. Further, divergence time estimation shows that Dacrymycetes evolved in the Neoproterozoic Era and Hymenochaetales diverged from Agaricomycetes during the Silurian period.

Summary
Reported to have evolved 1800 million years ago [1], fungi have a wide range of morphologies. Yeast) or filamentous and possess a wide range of fruiting bodies (Sporocarps).With the estimated fungal diversity of more than 13 million, they are the largest biotic community after insects [2]. Despite recent advances in molecular taxonomy the sequence information is far from complete in fungi [8, 9]. This information is of utmost importance in this group as fungi exhibits different morphological forms during the life cycle [10].
