Mycosource Inc. is a small company that specializes in Spawn production for the cultivation of Shiitake and Oyster mushrooms on hardwood logs.
These are “wood mushrooms” which means that they grow on wood (trees, fallen limbs, logs). They have high nutritional value.
Our premier product is sawdust spawn that is used to inoculate hardwood logs for outdoor hardwood log cultivation. NOTE AS OF SPRING 2015 – WE ARE UNABLE TO PRODUCE SAWDUST SPAWN PLUGS DUE TO A FAILURE OF OUR SOURCE SUPPLIER FOR THE MATERIALS TO MAKE THE SHEETS OF PLUGS. WE WILL BE SUPPLYING LOOSE SPAWN IN BAGS AND INOCUATION EQUIPMENT INCLUDING SEVERAL TYPES OF MANUAL AND SEMI-MANUAL INOCULATORS AS WELL AS WAX. We are confident that this more traditional method of inoculation using the tools that we will be offering will be efficient and economical regardless of the size of your project.
We ship spawn throughout Canada. We provide Customer Support to help you achieve success with your outdoor log cultivation project.
In addition we can produce bulk grain, and sawdust spawn on a contract basis for several other species of mushrooms, such as Reishi. We can also do contract sterilization of grain and/or your substrate mix.
We can also provide Consultation about indoor-based cultivation set up for a fee. This is done on a case-by-case basis.
We endeavor to act as an educational enterprise for the dissemination of products and information about mushrooms and mushroom cultivation as part of a diversified and sustainable forest ecosystem and are available for presentations on mushroom cultivation.
