Abstract A description is provided for Physoderma pulposum. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Chenopodiaceae (Atriplex spp., Blitum spp., Beta spp., Chenopodium spp.); Compositae (Ambrosia spp.); Umbelliferae (Aegopodium spp.). DISEASE: Parasitic in the leaves, petioles and stems causing fairly large and conspicuous galls (30, 125). The shoots of the host may become thickened and distorted and appear yellow to pink and finally brown. GEOGRAPHICAL DISTRIBUTION: Asia (Israel); Europe (Austria, Denmark, Germany, Hungary, Sardinia, Yugoslavia); North America (USA); South America (Argentina). TRANSMISSION: By dissemination of resting sporangia. Local dispersal by spores swimming in water films may also occur.

Abstract A description is provided for Physoderma alfalfae. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Medicago saliva (Lucerne, alfalfa) and Medicago spp. DISEASE: Crownwart of alfalfa. The disease is first noticeable in spring when the base of plant stems become slightly thickened. This thickening continues until large white warts or galls appear. Most galls reach full development in the summer, then decay rapidly with only a few surviving until the following spring (Jones & Drechsler, 1920; 58, 2281). GEOGRAPHICAL DISTRIBUTION: Asia, Australasia and Oceania, Europe, North America and South America (CMI Map 130, ed. 3, 1973). TRANSMISSION: By dissemination of resting sporangia. Local dispersal by spores swimming in water films may also occur.

Abstract A description is provided for Synchytrium macrosporum. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Karling (1964) lists the following hosts: Amaranthus berlandia, Ambrosia aptera, A. psilostachya, A. trifida, Ammi majus, Croton monanthogynus, Erigeron canadensis, Helenium tenuifolium, Iva ciliata, Modiola caroliniana, Nandina dornestica, Oenothera laciniata, Parthenium hysterophorus, Phyla incisa, Ratibida pinata, Riccinus communis, Rubus trivialis, Solanum elaegnifolium, Specularia perfoliata, Torilis japonica, Vicia faba, Vigna sinensis, Xanthium strumarium. However, experimentally infected hosts total over 1483 species in more than 933 genera of 185 families (57, 2425). DISEASE: Lavender-red galls develop on the leaves and stems of hosts. GEOGRAPHICAL DISTRIBUTION: North America (Texas). TRANSMISSION: No reports, but presumably by dissemination of resting spores, with local dispersal by zoospores swimming in water films.

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).
