马氏轮枝霉可使蘑菇子实体出现球形泡泡、畸形,使菌盖上出现初为褐色、后为灰色或杂色的病斑。但轮枝霉不会感染培养料,即使在紧挨着覆土前的那段时间也不会感染。蘑菇轮枝霉、疣孢霉、考氏头孢霉引起的病症亦相似。若用磨碎的石灰和泥炭(3:1)覆土,每米~2喷2升0.1～0.3％福尔马林液,可防治马氏枝霉等霉菌的最初感染。经处理每吨培养料可产菇100～170公斤,未经处理的仅产菇 M. marxianus mushroom fruiting body can produce spherical bubbles, deformities, so that the first appeared on the cover brown, gray or variegated lesions. However, the rotten mildew will not infect the culture material and will not get infected even during the period immediately before casing. Mushrooms rotiforms, Worm spores mold, Corynebacterium testum caused by the disease are similar. If crushed lime and peat (3: 1) soil, 2 to 2 liters per meter spray 0.1 ~ 0.3% formalin, can prevent the initial infection of molds such as M. Treated per ton of culture material can produce mushrooms 100 to 170 kg, only untreated mushrooms
