Apothecia produced in late spring, June to July, were used in this experimental series. Ascospores discharged at temperatures from 0 to 30℃ under humid condition. At temperatures above 20℃, all ascospores maintained in apothecia were discharged within a week, but apothecia kept continuously at 0 and 5℃ discharged only a few ascospores throughout the experimental period. No ascospores were discharged from apothecia that were kept under 94 percent relative humidity. Discharged ascospores germinated well within 48 to 72 hours at temperatures ranging from 10 to 25℃ without any maturation period. This was quite different and an interesting tendency compared with the results in the previous report in which ascospores produced in late autumn, October to November, germinated after a three months maturation period.
