一、外观鉴定优良菌种的菌丝洁白(草菇为银灰色)、健壮,气生菌丝繁茂,无杂菌,不干缩,不积水,不出菇蕾或耳芽,培养容器也不会破裂。但不同种类的菌种在外观上也有些差异,如平菇的气生菌丝异常繁茂,常爬满培养容器的空间;而滑菇、香菇的气生菌丝不甚繁茂,且较短。滑菇菌丝不甚洁白,常有黄褐色色素;香菇菌丝常有褐色色素,这都是正常现象。
First, the appearance of identification Fine strains of mycelium white (straw mushroom is silver gray), robust, aerial mycelium lush, non-miscellaneous bacteria, do not shrink, no water, no Gulei or ear buds, culture containers Will not break. However, different types of bacteria in the appearance of some differences, such as mushroom Pleurotus anomalous lush, often covered with room for training containers; and mushrooms, mushrooms of the aerial mycelium less lush, and shorter. Rousi mushrooms not white, often brown pigment; mushroom mycelium often brown pigment, this is a normal phenomenon.
