Radially flattened fibres and parenchyma cells, together with buckled and constricted rays were interpreted as a drought ring in Sycamore ( Acer pseudoplatanus L.). The damage was dated to late summer of 1972, an exceptional drought year in Scotland. Nectria coccinca (Pers. ex Fr.) Fr. and Verticillium tenerum (Nees ex Pers.) Link ( Nectria inventa Pethybridge) were the two organisms found almost exclusively in bark and wood of lesions on stems and branches. These lesions were non perennating and had been formed at the end of the 1972 growing season.
