The 3-foot-long logs resting against the wall near my front door are not for firewood; they’re for eating. Not the logs themselves, of course, but what’s growing inside of them. As I write and as you read, thread-like fungal mycelia are spreading within, digesting wood and growing bigger and stronger. Sometime next fall, delicious shiitake mushrooms should start popping out of the bark.
Any old rotting log will not produce delicious, or even edible, mushrooms. A couple of weeks ago, I inoculated these logs with spawn of selected strains of shiitake mushrooms. The spawn originally came from www.fieldforest.net, via my friend Bill Munzer, who had some spawn left over from a shiitake growing workshop he recently held. The spawn arrives as inoculated plugs which get hammered into holes drilled into the logs. A coating of wax seals in moisture.
