According to the literature [5, 43, 146] the optimum temperature for mycelial growth of Agaricus bisporus is 23 to 25 °C, while for production of fruit bodies it is 15 to 20 °C. The growth rate of the mycelium quickly decreases above 25 °C. The heat tolerance differs from strain to strain, but most strains hardly grow above 32 °C and die at 34 °C [51]. Nothing is known from the literature about the influence of temperature on the growth of Coprinus comatus.
