Causes of dead mushrooms (1) Weak young mushrooms. After the casing soil is applied to the mushroom bed and before fruiting, if the mycelium grows too fast and the fruiting sites are too high, the young mushrooms that form are too densely packed, causing the ones with insufficient nutrient supply to die. (2) Excessive temperature. If the temperature stays above 21°C for several consecutive days during the fruiting period, the young mushrooms will shrivel and die from heat damage. (3) Excessive humidity. When the relative humidity in the mushroom house is above 95% at high temperatures, if the doors and windows are closed after watering, the surface of the mushroom bed becomes waterlogged, causing the young mushrooms to suffocate and die.
