Abstract
AN interesting study of spore discharge in Lyco-perdon perlatum has been made by P. H. Gregory, using ultrabigh speed Schlieren cinematography (Trans, britt.Mycol. Soc., 32, Pt. 1, 11 ;. 1949). Spare discharge is brought about by raindrops of 1 mm. diameter or more falling on the flattened endoperidium. The puff of spores thereby induced reaches a height of 1 cm. approximately one hundredth of a second after impact. Velocities of tne spores on. emergence are in the order of 100 cm./sec. The film is run at a speed of 600–1,770 pictures per second, and a time-base controlled by tuning fork is marked on the edge of the film. This fascinating method of approach might be applied to many other similar problems.
