About annoying green mold

Green mold is a common hazard for mushroom/mycelium. Green mold often appears my experiments. It caused my experiments always fail.

The inflected area is easily break up while healthy mycelium is close-connected.

I discover that only part of area inflected with green mold. Another area of mycelium still is healthy.

I tried to take the mycelium with inflection under the room light to fruit mushroom. It is suscessfilly fruiting on the healthy area.
