sentences:  Thus, low durations of powerful storms are enough to induce a significant amount of spore dispersal.However, no correlation has been established between precipitation intensity and ascospore density, indicating that ascospores are not actively dispersed by rain splashes; rather, they are forcibly ejected into air currents, granted by the long beak and narrow restricted ostiole of the perithecium and the expulsion of spores from high  internal pressure caused by a swollen, wetted perithecium.Spores are not released until the first precipitating event that causes the perithecium to swell; afterwards, subsequent precipitation immediately releases spores, but the maximum rate of ascospore release is not obtained until 3 to 5 hours of precipitation.
