Abstract A description is provided for Seiridium cardinale. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Cupressus macrocarpa, C. lusitanica, C. forbesii, C. pygamaea, C. sempervirens, Chamaecyparis lawsoniana, Thuja plicata, Libocedrus decurrens, Juniperus decurrens var. femina. DISEASE: Coryneum canker of Cupressus. The first sign of infection consists of a depressed, slightly discoloured area of young bark about 10-15 mm diam., exuding fresh drops of resin. This will enlarge, becoming necrotic in the centre, with collapse of these tissues and hypertrophy at the end of the canker thus formed. GEOGRAPHICAL DISTRIBUTION: Australia & Oceania (Australia, New Zealand); North America (USA; California); South America (Argentina); Africa (South Africa); Europe (Italy, France, Spain, Greece). TRANSMISSION: Mainly by conidia which are liberated from acervuli at the edge of active cankers by a splash take-off sequence. Transmission by transport of infected nursery stock to fresh planting areas has occurred.
