Life history of Lentinus edodes
After maturing, the spores of Lentinus edodes will eject from the pleats, and under suitable conditions, the spores will germinate and produce germ tubes. The germ tube grows apically and branches into hyphae. The uninucleate hyphae of Lentinus edodes can form binucleate hyphae only after heterounion. The binucleate hyphae continue to grow and form lock-like combinations to proliferate cells and multiply in the matrix to form mycelium. The mycelium continues to grow and develop and accumulate nutrients, which will form fruiting body primordia and rapidly grow into mushroom buds under suitable conditions. After the fruiting body matures, it can reproduce the next generation, which is the life history of Lentinus edodes.
The life cycle of Lentinus edodes from spore germination to the formation of new spore ejection takes about 12 months or even longer under natural conditions, while artificial cultivation with sawdust only takes 4 months.

Fast-growing and High-yield Management techniques of Lentinus edodes
In the fast-growing and high-yield production of Lentinus edodes, its supporting management technology is very important, which directly affects the yield and quality of Lentinus edodes. First, the management of the inoculation period, move the inoculated bag to the culture room, the room temperature is controlled at about 25 ℃, and the relative humidity is below 75%. During the germicidal period, due to the heat released by mycelium respiration, the temperature in the bag will be 2 / 4 ℃ higher than that outside the bag. During the germicidal period, attention should be paid to prevent the temperature from being too high, especially the room temperature should not exceed 25 ℃ in the middle and later stage. 15-20 days when the hyphae grow to the mycelium.

Necessary conditions for the growth and development of Lentinus edodes
1. Nutritious Lentinus edodes is a kind of higher wood rot fungus. The carbon source for its growth comes from lignin, cellulose, nitrogen source and inorganic salt, and is taken from wood bark or wheat bran (rice bran) added to sawdust medium. After Lentinus edodes was inoculated into Lentinus edodes, the culture material was decomposed into small molecular substances which could be absorbed and utilized by the mycelium of Lentinus edodes, and the mycelium biomass increased with the increase of culture time. When the culture material was fully degraded, the mycelium of Lentinus edodes accumulated a lot of nutrients, which laid the material foundation for the occurrence of fruiting body.
