This issue’s cover shows an experimental array of Silene latifolia flowers, used to study the spread of the anther‐smut pathogen, Microbotryum lychnidis‐dioicae. The array contains a mixture of healthy and diseased flowers, where the influence of the pathogen is to replace the pollen with dark‐colored fungal spores that are conspicuous against the white flower background. Pollinators then pick up and distribute the spores during normal foraging visits.
