Interesting, one of my friends started his own mushroom-growing business called Nuvedo (https://nuvedo.com/). And from reading their blog https://nuvedo.com/blog/ I learned that mushrooms are some kind of superfood (similar to how the west sees acai or kale?).

Mushrooms probably wouldn't make too much of India's exports though, so remains to be seen how much of a superpower they could become.
