In Vienna, Austria there's http://www.hutundstiel.at http://www.hutundstiel.at (german only for some reason). They also grow oyster mushrooms on coffee waste and even pick up the waste by bike. Recently there are even sausages made of oyster mushrooms (http://www.hermann-fleischlos.at http://www.hermann-fleischlos.at also german). What's interesting about them is that they taste incredible (vegetarian soy based sausages I tried are really terrible). Anyway, it's really good to see some innovation going on with mushrooms!
