Many edible mushroom growers reported that due to the use of inferior strains, cultivation failed, but they did not know how to identify the quality of strains. For some authors to introduce a simple identification method of the advantages and disadvantages of several species of bacteria: Ping Ru mycelium white, dense, thick, was cotton wool, there is a wall climbing phenomenon, for the fine strains, strains with wood chips cultured, is decomposed The sawdust was light yellow and had a small amount of primordium. It was a good strain. If the hyphae are sparse or bundled, the culture medium of the cottonseed hulls is dark red, the sawdust medium is whitish, the hyphae are detached from the bottle wall, and the hyphae are atrophied. The yellow effusion is present at the base of the bacteria bottle, or mold spots appear on the surface of the culture material. Inferior bacteria species. Flammulina mycelium is white, thick, or has a fine-powdered appearance, and has a strong life force. In the later period, the fruiting bodies appear as bundles on the culture materials, which are excellent strains. Hyphae can not grow deep downwards, and there is an aging strain that causes vomiting of yellow water. It cannot be used. Mushroom hypha white, cotton wool-like, uniform growth, no thick bacteria, easy to form the original base, is a good strain. The mycelium in the bottle is sparse, the mycelium is detached and atrophied, and the bacteria are browned, which is a degenerate strain or an aging strain. The mycelium of the straw mushroom is white and transparent, and it is a kind of young species. The hyphae is yellow-white or grayish-white and transparent. It is an age-appropriate species; the mycelium is dense and the mycelium is atrophic, and the upper hyphae are atrophied. Species. Excessively overgrown strains cannot be cultivated. Mushroom mycelia gray, slightly blue, thin thread, no yellow-white bacteria were, for the fine strains. Mycelium is light yellow, atrophied, or the bacteria on the top of the bottle are too thick. Hericium erinaceus mycelium is white, thick, and evenly distributed. It forms fruiting bodies on the surface of the culture medium. The fruit body is thick and the bacterium is long. It is an excellent strain. The hyphae are sparse, slender, and unevenly distributed, or the primordium appears when the hyphae have not occurred in half, or the bottom of the bottle is filled with yellow mucus, all of which are inferior species.
