Surveys in grapevine nurseries and in vineyards of Apulia (southern Italy) detected a white bark and wood rot on grapevine propagation material and on standing vines. Mycological analysis and experimental inoculations showed the causal agent to be a Collybia sp. This finding suggests that growers should pay more attention with the sanitary status of grapevine propagation materials.
