Abstract:  “The mycelial growth of Gyromitra esculenta (Pers.) Fr. was studied on four different culture media, complete medium, Hagem’s medium, minimal medium and Czapek’s medium. The mycelium was found to grow best on complete medium. One strain was subsequently cultured on complete medium at temperatures ranging from 6 to 27° C. The optimum temperature for mycelial growth was 15-23° C. At 25° C and 27° C the vegetative growth was slower and some morphological changes were observed in the mycelium.
The mycelium started to grow within 24 hours after cold treatment of one two and three weeks at -4 C. After cold treatment of one, two and three weeks at -15° C and -25° C, no growth was observed within 24 hours. At -15° C the duration of the cold treatment was significant for the recovery of the mycelium; it clearly grew better after one than two or three weeks in cold. The same tendency was observable after cold treatment at -25° C.”
