Well nothing exciting is happening with either the king oyster or the beech.
Although, the king oyster mycelium I left on the cardboard appears to be recovering. If you remember, I had given it a light spraying of hydrogen peroxide, and then placed two strips of fresh cardboard on top of it. My plan being to have a back-up stock of mycelium if my 1/2 pint jars become infected.
As for the beech, I can see the start of some fuzzy mycelium beginning to grow.
