Abstract A description is provided for Wojnowicia hirta. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Cereals and grasses (Agropyron, Avena, Bromus, Calamagrostis, Calamovilfa, Dacrylis, Distichlis, Elymus, Festuca, Hordeum, Koeleria, Phleum, Poa, Secale, Sorghastrum, Sorghum, Spartina, Stipa, Triticum). DISEASE: Secondary foot rot or root rot of cereals and grasses. Also referred to as rot of mature straw. Rot of cereals and grasses is very common (5, 223; 6, 272; 7, 370; 11, 503; 12, 685; 16, 242; 48, 120; 1602) and considered to be of definite economic importance (Sprague, 1950). In France infected wheat plants have been reported to become etiolated and progressively shrivelled without producing lesions (4, 662). As the disease progresses, cells at the base of the culms were claimed to collapse resulting in the breaking of the stems and general lodging of plants in infected areas (5, 223; 12, 685). Subsequently pycnidia were reported appearing on lower leaf-sheaths above and below the soil line (1, 288). Sometimes affected wheat plants have been found to show discolouration of culm bases and roots (5, 223), or dark brown to black spots and streaks on the stem which are partly superficial (7, 370, Sprague, 1935). GEOGRAPHICAL DISTRIBUTION: Africa (Morocco, South Africa, Tunisia); Asia (Turkey); Australasia and Oceania (Australia, New South Wales, South Australia, Victoria, Western Australia); Europe (Belgium, Bulgaria, Czechoslovakia, Finland, France, Germany, Irish Republic, Italy, Netherlands, Poland, Rumania, Spain, Switzerland, UK, USSR); North America (Canada, Alberta, Saskatchewan; USA, Arkansas, California, Colorado, Dakota, Idaho, Kansas, Montana, Oregon, Washington, Wyoming). TRANSMISSION: Infected soil has been found to be the chief mode of transmission where stubble has been ploughed under (3, 191). It has also been reported that W. hirta occurs on culms overwintered in the field usually at the 2nd node (9, 639-641).

Abstract A description is provided for Rhynchosphaeria cupressi. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Cupressus macrocarpa, C. lusitanica, C. arizonica, C. torulosa, Cupressocyparis lawsoniana, Juniperus procera, Thuja orientalis. DISEASE: Stem and branch canker of young trees. Cankers are associated with profuse resin flow and in advanced states, a flattened, winged condition of the tissue may be produced. Cankers may girdle and kill young trees. GEOGRAPHICAL DISTRIBUTION: North America (USA); Africa (Kenya, Uganda, Tanzania, Malawi, Rhodesia, South Africa); Australia and Oceania (New South Wales, Queensland, Victoria, Tasmania, South Australia, New Zealand); Asia (India (Bakshi et al., 1970)). TRANSMISSION: Conidia and ascospores are released under moist conditions and dispersed by a splash take-off mechanism, after which they have a limited air-borne range (33: 191). Long distance spread is probably effected by human agencies.
