Abstract
Violent spore discharge in mushrooms and other basidiomycetes uses the same mechanism: Due to certain morphological and physiological properties of the spore wall, two liquid droplets are formed. When these two droplets coalesce, the surface area of the fusion droplet is reduced, which instantly generates energy utilized in spore discharge. Investigations were made with Itersonilia perplexans, a ubiquitous fungus which is easily grown in culture. The film introduces the organism, shows for the first time the process preceding spore discharge, and presents experiments which clarify the origin of the drops. The processes and physical forces during spore discharge are explained by animation. Includes time-lapse.
