Abstract A description is provided for Lophodermium agathidis. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. DISEASE: Lophodermium agathidis occurs on dead attached and fallen leaves. Virtually nothing is known about the ecology of this fungus. It seems likely however that, like many other members of the Rhytismataceae, the fungus colonizes the living plant, then fruits on those leaves after they have died. HOSTS: Leaves of Agathis australis, Beilschmiedia tawa, Dracophyllum latifolium, Knightia excelsa, Metrosideros excelsa, M. fulgens, Nestegis lanceolata, Rubus cissoides, Xeronema callistemon. Described originally on A. australis, this species is now known to occur commonly on many different native New Zealand plants. GEOGRAPHICAL DISTRIBUTION: New Zealand. TRANSMISSION: By air-borne ascospores in humid conditions.

Abstract A description is provided for Puccinia chrysanthemi. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Chrysanthemum boreale, C. decaisneanum, C. hortum, C. indicum, C. makinoi, C. pacificum, C. shimotomaii, C. shiwagiku, C. sinense and C. zawadskii. DISEASE: Black rust of cultivated chrysanthemum. Attacks mainly leaves, killing them and causing premature defoliation. Severe foliar infection in certain varieties is accompanied by slight infection of stems and occasionally of the involucre. Affected plants often become stunted and produce few flowers. Heavy damage was caused in Germany during 1926-27 (8: 242). GEOGRAPHICAL DISTRIBUTION: Africa (Congo, Ethiopia, Kenya, Malawi, Mauritius, Morocco, Rhodesia, South Africa, Tanzania, Uganda); Asia (China, India, Israel, Japan, Korea, U.S.S.R.); Australasia and Oceania (Australia, Hawaii, New Zealand, Tasmania); Europe (Azores, Belgium, Bulgaria, Denmark, Finland, France, Germany, Great Britain, Holland, Iceland, Italy, Malta, N. Ireland, Norway, Poland, Portugal, Spain, Sweden, Switzerland, U.S.S.R., Yugoslavia); N. America (Bermuda, Canada, U.S.A.); Central America & W. Indies (Dominican Republic); S. America (Argentina, Chile, Uruguay). (CMI Map 117, Ed. 2, 1964). TRANSMISSION: Teliospores have been reported from Japan, N. America and Sweden; elsewhere the fungus is known in the uredial stage only. It has been shown that urediospores wintered in the open can germinate in the spring (Jacky, Z. Pfl.-Krankh. 10: 132, 1900; Zbl Bakt. II, 10: 369, 1903; 18: 88, 1907). It is believed that urediospores can remain viable through winter on woodwork, glass, fallen leaves or in the soil (Pape, Gartenwelt 32: 623, 1928). No perennial mycelium has been found (Gibson, New Phytol. 3: 188, 1904).

Abstract A description is provided for Lophodermium foliicola. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. DISEASE: Fruits on dead fallen leaves under Crataegus where they can accumulate over winter; low bushes surrounded by Urtica and Rubus fruticosus agg. are among the most likely places to find it; probably less local than records suggest, as the conditions in which it is found deter less dedicated observers. It seems likely that, like many other members of the Rhytismataceae, the fungus colonizes the living plant, then fruits on those leaves after they have died. HOSTS: Leaves of Acer orientalis, Cotoneaster integerrimus, C. vulgaris, Cotoneaster sp., Crataegus coccinea, C. crus-galli, C. monogyna, C. oxyacanthoides, Crataegus sp., Pyrus amygdaliformis, P. communis, Pyrus sp., Rosaceae gen. indet., Sorbus torminalis. Records on genera other than Crataegus, particularly those not in the Rosaceae. need re-evaluation. GEOGRAPHICAL DISTRIBUTION: Austria, Azerbaijan, Belgium, former Czechoslovakia, Eire, Finland, France, Germany, Greece, Ireland, Italy, Russia (Kursk Oblast), Spain, Sweden, UK (England, Scotland, Wales), Ukraine. Altitude records exist up to 1580m (Spain) and 1050m (Greece). Widespread but local throughout Europe and just into Asia on dead fallen leaves of various members of the Rosaceae, but particularly Crataegus. TRANSMISSION: By air-borne ascospores in humid conditions. In the temperate northern hemisphere, ascocarps probably mostly open in late summer and early autumn.

Abstract A description is provided for Xanthomonas pruni. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Prunus amygdalus, P. armeniaca, P. avium, P. cerasus, P. davidiana, P. domestica, P. japonica, P. mume, P. persica, P. salicina and other species of Prunus (30: 48; Elliott, 31: 105, p. 114). DISEASE: Bacterial leaf spot on leaves, twigs and fruit of plum, peach, apricot and cherry; black spot of plum and peach; bacterial shot-hole of leaves. Previously referred to in earlier literature as bacterial canker of stone fruits, name now reserved for the disease caused by Pseudomonas morsprunorum and P. syringae. Shot-hole on the leaves of trees infected by X. pruni differs from that of fungal origin by the presence of bacterial ooze and in the shape of the leaf perforations which are generally irregular or elongated instead of round (35: 530). Atypical symptoms have been reported on peach leaves (19: 292). Symptoms on cherry fruit differ from those on peach and plum (14: 178). Branch cankers on peach are shallow and do not become perennial as on plum. On peach they were not observed to girdle the stem (10: 224). GEOGRAPHICAL DISTRIBUTION: Africa (Southern Rhodesia, South Africa); Asia (China, India, Japan, Korea, U.S.S.R.): Australasia (Australia, New Zealand), Europe (Cyprus, Italy, Romania); North America (Bermuda, Canada, U.S.A.): South America (Argentina, Brazil, Uruguay). In the U.S.A. the disease occurs on stone fruits in at least 26 States (30: 48; CMI Map 340, Ed. 2, 1964). TRANSMISSION: Xanthomonas pruni is disseminated by wind and rain (29: 218). The pathogen enters leaves through the stomata, and fruit infection appears to follow that of the leaves, probably as a result of leaf drop during rainy spells (7: 76). Primary leaf infection on peach originates in twigs with spring cankers (Thornberry & Anderson, 1933) or terminal die-back in which the pathogen overwinters (39: 600). Summer cankers on peach are only important under certain conditions for initiating spring infection (34: 732, 379), but on plum and apricot they play a more permanent role since the infection originating in the current season's twigs continues to develop in them during the following spring (Anderson, 1956). Overwintering on plum buds and fallen leaves has also been reported (41: 608). Species of Cicada may damage the bark of plum in New Zealand and thus provide points of entry (32: 322). The chief means of transmission of the pathogen in New Zealand is in budwood and root-stocks (42: 202).

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 Acroconidiella tropaeoli. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Tropaeolum spp. DISEASE: Causes severe losses in nasturtium seed fields in coastal California. It produces a yellowing and death of the leaves after mid season and this reduces yield. The fungus occurs sometimes on stems and is present on seeds but is most abundant on leaves where it forms characteristic irregular or subcircular brownish or purple spots visible on both sides. These are up to 1 cm diam. or often larger through confluence, the centres later shrivel and the surrounding tissues may form a broad yellow margin. GEOGRAPHICAL DISTRIBUTION: Argentina, Australia, Ceylon, Ethiopia, Guatemala, Haiti, India, Jamaica, Kenya, Mauritius, New Guinea, New Zealand, Tanzania, Uganda, U.S.A. TRANSMISSION: The pathogen is borne internally and externally in up to 93% of commercial nasturtium 'seed', persisting for at least 3 years in the form of thick-walled mycelium in the pericarp and seed.
