Fine strains of edible fungus is the basis for the success of cultivation. Through the shape, color, taste, like the four aspects to identify the advantages and disadvantages of species. Shape: see the bacteria bottle mouth or pocket opened, bottle or bag rupture at the Department, bandaging is tight and so on. If you do not meet the requirements, there is the possibility of infection by bacteria. Color: All good species, all bottles or bags from top to bottom, mycelium are uniform white. If only white, not good. Yellow mycelium, indicating that the recession. If the red, green, black and other colors, is already contaminated by bacteria,
