Abstract A description is provided for Kuehneola uredinis. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On numerous Rubus species including American dewberries, blackberries, loganberries, ornamental and wild species. In Europe on R. fruticosus agg. (European blackberries). There are a few unconfirmed records on R. caesius (European dewberry) and on R. idaeus (red raspberry). DISEASE: Rust on canes and leaves of blackberries, loganberries, dewberries, ornamental and wild Rubus species. GEOGRAPHICAL DISTRIBUTION: Africa (S. Africa); Australasia (Australia, New Zealand); Europe (widespread); N. America (Eastern Canada, Eastern U.S.A.); South America (Argentina). TRANSMISSION: Teliospores germinate in late summer and autumn; pycnia and uredial aecia occur on leaves and stems shortly after (Fischer & Johnson, 1950; Wilson & Henderson, 1966). In spring the first true uredia appear on the fruiting canes and their spores infect the newly formed leaves. Thus the fungus overwinters either as aecial urediospores or mycelium in the canes. In less severe climates the true urediospores overwinter and the other stages of the life cycle are omitted.

Abstract A description is provided for Podosphaera leucotricha. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Malus spp., chiefly on M. pumila (apple), peach (Prunus persica), quince (Cydonia ualgaris) and Photinia spp. also attacked (Hirata, 1966). Also reported on almond fruit (43, 2544). DISEASE: Powdery mildew of apple. GEOGRAPHICAL DISTRIBUTION: Africa (? Kenya, Rhodaia, South Africa, Tanzania); Asia (China, India, Israel, Japan, U.S.S.R.); Australia and New Zealand, Europe (widely distributed) North America (Canada and U.S.A.); South America (Argentina, Brazil, Chile, Colombia, Peru). (CMI map 118). TRANSMISSION: Overwinters on host as dormant mycdium in blossom buds. The role of deistothecia in overwintering is doubtful. Spread by wind-borne conidia (Anderson, 1956).

Abstract A description is provided for Ustilago hypodytes. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: A wide range of grasses, including species of Agropyron (many), Ammophila, Brachypodium, Bromus, Calamagrostis, Diplachne, Distichlis, Elymus (many), Festuca, Glyceria, Hilaria, Hordeum, Haynaldia, Lygeum, Melica, Orysopsis, Panicum, Phalaris, Phleum, Poa (many), Puccinellia, Secale, Sitanion, Sporobolus, Stipa (many), and Trisetum. DISEASE: Stem smut of grasses. GEOGRAPHICAL DISTRIBUTION: Chiefly a temperate species found in Europe (including Denmark, Finland, France, Germany, Hungary, Italy, Romania, Sweden, Switzerland, UK, USSR, Yugoslavia) and North America (Canada, USA) and extending to central and South America (Argentina, Peru, Uruguay), N. Africa (Libya, Morocco, Tunisia), Japan, Australia and New Zealand. TRANSMISSION: Not fully understood, though inoculation experiments have demonstrated that infection occurs in mature vegetative plants (possibly through meristematic tissue), not seeds or flowers (22, 240; 24, 511). Once established, infection is systemic, probably overwintering in the root system and spreading by vegetative multiplication of host plants as well as from plant to plant (24, 511; 19, 720).
