Summary Bark isolations from cankers on Cupressus macrocarpa in southern England yielded Seiridium cardinale, Pestalotiopsis funerea and Pestalotiopsis monochaetioides . The recovery pattern of the three fungi indicated that only S. cardinale was a primary pathogen; the two Pestalotiopsis species being secondary. Pathogenicity data obtained following the inoculation of C . macrocarpa branches with mycelium of the three fungi confirmed this view. No evidence of vegetative incompatibility was found in S. cardinale , but five vegetative‐compatibility (vc) groups were found in P. funerea and six in P. monochaetioides . Different vc groups of the two Pestalatiopsis species were often found in the same S. cardinale lesion, suggesting that a number of separate colonization events were involved. It is possible that this sometimes leads to complete replacement of the pathogen.
