Abstract: The Western Himalayas, India is known to be one of the word’s hotspots of biodiversity but still the diversity of some economically important fungi like Cantharellaceae has not been explained properly from this region. In the present research work several fruiting bodies of Cantharellaceae were collected from different parts of Western Himalayan region and characterized. Macromorphological and microscopical characters followed by molecular characterization (both the ITS and LSU dataset) i.e., morpho-genetic studies confirmed the identity of these fungi. The present research work described 13 species of Cantharellus, among these, 8 were new taxa which includes C. applanatus sp. nov., C. elongatipes sp. nov., C. fibrillosus sp. nov; C. himalayensis sp. nov., C. indicus sp. nov., C. natarajanii sp. nov., C. pseudoformosus sp. nov., and C. umbonatus sp. nov. as new to the world while C. miniatescens Heinem was new record from the Indian subcontinent. Three species of Craterellus (Craterellus cornucopioides var. mediosporus Corner, Cr. dubius Peck and Cr. cinerius Fries) were reported as new records from the Indian subcontinent. Craterellus indicus sp. nov. was new report from the world. All these Cantharellaceae fruit bodies were also analyzed for nutritional properties. Nutritional profile of such Cantharellaceae species revealed that, these mushrooms provide key nutrients such as protein and carbohydrates, beside antioxidants, amino acids and vitamins. The bacteria associated with the fruit bodies of Cantharellaceae were studied. Bacteria were isolated from internal tissue of sporocarps and differentiated on the basis of REP- and BOX-PCR fingerprinting. Biochemical and 16S rRNA profile revealed that the isolates belonging to nine different genera which includes Hafnia sp., Enterobacter sp., Ewingella sp., Rahnella sp., Gamma proteobacterium, Pseudomonas sp., Stenotrophomonas sp., Alcaligenes sp. and Bacillus sp. So, the present study was undertaken to explore and assess the diversity and distribution of Cantharellaceae from Western Himalayas for first time along with their nutritional properties and host association between fruit bodies of Cantharellaceae with endophytic bacteria.
