Single conidium isolates of Cryptostroma corticate from 14 woodland sites in Wales and southern England belonged to 11 different somatic‐compatibility groups. Members of the same group intermingled on 3% malt agar, whereas those of different groups were mutually antagonistic, a zone of sparse mycelium developing between paired colonies. Isolates from the same stroma were all of the same compatibility group, and this was also sometimes true for isolates from different trees at the same woodland site. Some compatibility groups occurred in widely separated locations, but others seemed to be peculiar to a particular woodland. The implications of this population structure for the life cycle and epidemiology of the pathogen are discussed.
