Abstract: Morchella esculenta is one of the well-known wild edible fungi in China which is delicious and rich in nutrition. The mycelia were isolated from the wild and the biological characteristics were studied. The results showed that seven strains of Morchella esculenta could grow when temperature ranged from 12℃ to 30℃, the suitable ranged from 20℃ to 30℃,and the optimum temperature was 25℃. Seven strains of Morchella esculenta could grow among the scope of pH6.0-8.0, and the optimum pH for Morchella esculenta of 01,05and 07 was 7.0, 02 and 03 were 8.0, 04 and 06 were 6.0 and 6.5 respectively.Seven strains of Morchella esculenta could absorb a lots of carbon and nitrogen sources. But the optimum carbon sources for Morchella esculenta of 02,03,04,05and 06 was glucose, starch,glucose,sucrose and starch respectively,and the optimum nitrogen sources for Morchella esculenta of 01, 04, 05 and 06 was peptone, 02 and 03 were urea, 07 was peptone and NH4NO3.
