Abstract
IN the genus Chaetomium the fruit-body, a perithecium, is ornamented with a large number of apical hairs which are either spirally coiled or dichotomously branched. The ascospores are released within the perithecium by breakdown of the ascal walls and the spores ooze out of the ostiole and either form a spore tendril or become entrapped in the apical hairs. Hitherto the mechanism of spore dispersal has been obscure, but recent experiments have shown that entire fruit-bodies as well as spores can be dispersed by falling water drops.
