1. Occurrence reasons: 
A. Low temperature, excessive humidity and poor ventilation. Under low-temperature condition, poor ventilation and excessive humidity in mushroom greenhouse could result in small evaporation and a layer of accumulated water film on mushroom cap.
B. Temperature shock and excessive temperature differentials meaning above 10 degrees do terrible damage on the cell growth of mushroom cap.
2. Control methods: 
A. Warm up and keep warm. In low-temperature season, when the temperature of greenhouse is too low at late night, be sure to adopt measures to warm up so as to facilitate the normal growth of sporocarps, meantime, pay attention to enhance the measures on heat preservation so that the heat loss of mushroom greenhouse could be reduced.
B. Reduce the amount of water-spraying, pay attention to the ventilation after water-spraying. What’s more, be sure not to spray water repeatedly and after spraying water, ventilate immediately to prevent fungus cap from accumulating water.
