Hi Eric, Oyster mushrooms can be cultivated on paddy straw or for that matter on various other media like wheat straw, bagasse, etc. They are different in looks from the button mushrooms as they resemble the bracket mushrooms.
I think it is the button mushrooms that need the dung for their cultivation. Anyway here are a few webllinks. http://en.wikipedia.org/wiki/Oyster_mushroom http://planning.up.nic.in/innovations/inno3/ph/oyster.htm http://icargoa.res.in/oyster_mushroom.htm Regards Tony ----------- Tony de Sa Ph: +91 832 2470 148 M: +91 9975162897 E: tonyd...@gmail.com ------------------------------------------------ "The future will be better tomorrow." - Dan Quayle
