"Whitish smoke in the movie are small droplets containing smreps (deliberate misspelling of word for male gametes). The smreps in the droplets are still un-motile. When touch the water, they begin to swim. In our experiments, misting with water is trigger of the explosion. If antheridia were mature, the explosion begin within few minutes. The event continued about for 10 min. Intense light for video recording also seems to accelerate the phenomenon. Each antheridia is deeply sunk in a cavity of antheridiophore and there is a very small pore on the top of each cavity. Swollen cells of surrounding tissue might cause the pressure force. Cavers (1903) and Muggoch & Walton (1942) also discussed about the mechanism, but, I think no one examined about the detail mechanism of the phenomenon. In Hiroshima, the season of mreps dispersal is Spring (April to May). In our field observation, we detected many airborne smreps in the sunny day after rain shower. I do not have detail data about how many species of liverworts have airborne mreps. At least, Asian species of Conocephalum (C. japonicum) do in the same manner." M. Shimamura
