S ummary Horizontal spore discharge has been studied in the genera Daldinia, Sordaria, Pleurage and Ascobolus . The average distance of discharge for the full spore‐complement of the ascus increases with the size of the projectile. In Pleurage taenioides a consideration of the form of the ascus jet, as caught on a rapidly rotating disk, suggests that as the four spores are shot from the ascus the vigour of discharge tends to fall with the escape of successive spores.
