The fruiting body is 18. Below C can not differentiate and develop, at 24-28. The differentiation and development between C was rapid, and the mycelium growth temperature was 3-40. C, to 24-30. C grows rapidly. Spore germination and mycelial growth do not need light, while the differentiation and development of fruiting bodies need astigmatism and directed light.
