Abstract A description is provided for Coniothyrium minitans. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Sclerotinia sclerotiorum, S. trifoliorum and, under laboratory conditions, can attack sclerotia of Botrytis cinerea, B. fabae, B. narcissicola, Sclerotinia minor and Sclerotium cepivorum. DISEASE: Hyperparasite of sclerotia of phytopathogenic fungi such as Sclerotinia sclerotiorum and S. trifoliorum (55, 4614, 4972). GEOGRAPHICAL DISTRIBUTION: Australasia & Oceania (Australia, New Zealand); Europe (Britain, Finland, East Germany, Hungary, Poland); North America (Canada, USA). TRANSMISSION: By conidia and mycelia dispersed in the soil from disintegrating infected sclerotia which are covered with numerous pycnidia releasing abundant conidia. It has also been suggested that disintegrating infected sclerotia could be dispersed with the mycoparasite by fungus gnats (Mycetophilidiae) (Turner & Tribe, 1976).

Abstract A description is provided for Sclerotium cepivorum. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On onion, chives, garlic, leek, shallot, Allium canadense, A. fistulosum, A. vineale and other species of Allium. Has been recorded on Zephyranthes, Belamcanda chinensis (probably saphrophytic on the latter; 50, 1846) and on linseed, clover, cabbage and tomato by inoculation (49, 720). DISEASE: White rot of onions and their allies. GEOGRAPHICAL DISTRIBUTION: Africa (Egypt, Libya, Rhodesia, S. Africa); Asia (India, Japan, Pakistan); Australasia (Australia, New Zealand); Europe (Azores, Bulgaria, Cyprus, Czechoslovakia, Denmark, Finland, France, Germany, UK, Italy, Netherlands, Norway, Romania, Spain, Sweden, Switzerland, USSR, Yugoslavia); North America (Canada, USA); South America (Argentina, Bolivia, Brazil, Colombia, Peru, Uruguay). (CMI Map 331, ed. 2, 1968). TRANSMISSION: Soil-borne. Inoculum remains viable and capable of reinfecting crops for at least 8 yr (17, 717), and there is a limited amount of saprophytic growth in soil (33, 134; 36, 567). Also dispersed on diseased seedlings and sets and by agricultural practices which disseminate soil particles and refuse from diseased crops; can survive passage through domestic animals (22, 422; 54, 3585).

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).
