I mentioned it in another post. In
Sepp Holzer's
permaculture book he hangs
mushrooms in a mesh bag over an area he wants inoculated, and puts a little chime"tapper" (something soft) by it so it releases it's spores. I'm not really sure why you would want to blend it? Seems to me blending is sort of a destructive process. I would just make sure you try and inoculate an area that is similar to where they were picked. Ie tress species, leaf litter or grassy. We used to just place wine caps face down on
wood chips if we wanted new sites.
