First pic dead Ash with black ovoid crevasses in trunk and distorted woody growth (Feb). Second and third pics, living Ash with same or similar on trunks (May). Quite a few of our Ashes exhibit evidence of this but remain apparently healthy. Disease appears to have been present for many years. Suspect bacterium P. syringae / P. savastanoi can anyone confirm.
