Mycelial cords of Bamboo fungus base are connected with bamboo rhizome and withered bamboo root, long-skirt Bamboo fungi are mostly produced in high-temperature and high-humidity regions, but short-skirt Bamboo fungi are mostly produced in moist heat environment. When spores germinate and form hyphae, the hyphae get nutrition by decomposing organic substance such as dried beancurd sticks and enter reproductive growth period, mycelia form countless mycelial cords, at the front end they inflate and develop knot primordia, under proper condition after one month growth the primordia form fungus-buds, the shape likes an egg.
When fungus-bud bulges like peach on its top, mostly on the morning of a sunny day the bulge will crack, mushroom cap will appear first, mushroom stem will extend in succession, at the noon when the stem grows to a certain height it stops extend, mushroom skirt unfolds downward from within the cap, when air relative humidity is 95%, mushroom skirt will grow normally, if the temperature is lower and the humidity is less mushroom skirt cannot unfold normally. At 4～5 pm the sporidia on the cap will mature and begin to autolyse and drop on the ground, at the same time the whole sporocarp will shrink and fall.
Bamboo fungus is typical medium temperature fungus. Growth temperature of the hypha is 4-28℃, best temperature is 20-23℃; if the temperature is lower than 16℃ or higher than 36℃, the growth will become slowly. Sporocarp forming temperature is 17-29℃, 20-24℃ is the appropriate temperature, best temperature is 22℃; if the temperature is higher than 28℃ it grows slowly; if the temperature is over 35℃, it will stop growth; if the temperature is lower than 15℃, the development will slow, fungus ball will shrink or appear malformation. The temperature mentioned here is environment temperature the hyphae and sporocarp are in, that is the temperature of 5-20cm under the earth for substrate, and 1-30cm under the earth for sporocarp differentiation. Because the temperatures of the earth’s surface and underground are very different at the same time, in general surface temperature is higher than underground, more deep the temperature is less. When cultivation you should pay attention to this.
