Can mushrooms be grown on pecan shells?

I've still got a bunch of pecan shells and was wondering if I could use them to grow mushrooms. Particaularly oyster mushrooms. Would I need to add any kind of nutrion to it or just use them like wood chips?

I do not have any experience growing mushrooms but I have books about growing mushrooms! Pecans are in the Carya genus and many mushrooms like to growing on that genus. In the book "Growing Gourmet and Medicinal Mushrooms Book" by Paul Stamets, writes about using cottonseed and peanut shells as a growing medium. I would try using pecan shells mixed in with the growing medium in starting with small amounts and seeing what happens. I live in an area with a lot of pecans and it would be cool to grow mushrooms too.

Oyster mushrooms are very forgiving on what you grow them on. I’d think it would work but have no idea how long it would take for the mycelium to colonize the shells. Please keep us informed.
