Definitely it is some species from Agaricaceae family. It's hard to identify this fungi only by the photo, but for me it looks like Chlorophyllum molybdites.
Either it is Chlorophullum or may be from Amanita group. Try taking spore print from this and you can also use the mushroomexpert.com to look for keys to identify it.
If you want to go further, just extract the DNA and send for sequencing.
I'm not familiar with what mushrooms occur in India. There are a lot of great mycologists there. (see http://www.fungiindia.co.in/ and http://ismpp.org.in/)
It looks like Chlorophyllum or something in Lepiota sensu lato.
