ABSTRACT
This article deals with a research programme that aims to address basic questions about the ecology and epidemiology of the fungus Nectria fuckeliana. In a second inoculation experiment in 2006, the early stages of infection will be observed in trees felled at regular intervals after inoculation. Analysis of infected wood by confocal and scanning electronic microscopy will show the location of the fungus within the tissues of the trees and the type of cellular damage it causes. A profile of the basic biology of the fungus is emerging from field and laboratory observations and experiments. For instance, when adequete moisture is present Nectria ascospores ooze out of the fruiting bodies in droplets. In addition, free water is necessary for the Nectria ascospores to germinate.
