Propagating a shiitake mushroom for free: Success
According to some book
that has since faded into obscurity in my memory, the traditional
Japanese method of reproducing shiitake mushroom logs is simple. Just
cut a fresh log and set it beneath the old...and the fungi will move
down to colonize the new substrate.

I decided to try a
slightly modified method of that technique with a mini log in April
2015. To streamline the spread of mycelium, I
placed a wet sheet of corrugated cardboard between the fresh and
sure enough the white threads of fungi soon clambered on through.
Now, seventeen months
later, there's finally a tiny mushroom budding on my never-plugged log!
Yes, that's nearly a year later than the plugged logs fruited, proof
that the traditional technique is slower, if no less sure. Still, given
the simplicity of cut-it-and-touch-to-an-existing-log technique, it
seems to merit a repeat on a slightly larger scale.
