River City Mushrooms is a small business and passion project based in Winnipeg, Manitoba that strives to provide locally produced, seasonal harvests of high quality specialty mushrooms along with the materials and knowledge necessary for individuals to cultivate their own delicious, gourmet mushrooms right at home.

By learning the skills and techniques used to cultivate fungi, these versatile and highly adaptable decomposers can be used as a conduit with which to help create ecologically resilient and sustainable communities. Mushrooms have the capacity to provide us with nutrition and medicine while also breaking down and liberating the components of organic materials to create healthy soils.
