Sonar, while I do not doubt for a moment that this establishment will replace the bad ones, I will not trouble them, the mechanics don't work for me. It is a pity that the contam was bacteria. If it were another fungus the mushroom could be isolated away. You place a second dish of agar over the first like an agar blanket - then you race the fungus, this keeps them from intertwining, keeps spores from the fungus you don't want from flying off to recolonize and usually, you will find that the mushroom will grow faster than fungus. At a certain point you can see through the agar at pure mycleium, then you slice through the sandwich and lay a slice on a new dish. It works rarely however, in competition with bacteria.
