Abstract A description is provided for Lophodermium nitens. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Haploxylon (five needle) pines, including Pinus cembra, P. monticola, P. strobus and P. lambertiana. DISEASE: Needle cast of pines. Darker (1932) considered this species to fruit only on older needles. It is, therefore, unlikely to be of commercial importance. GEOGRAPHICAL DISTRIBUTION: North America (USA, Canada); Japan; possible records from Europe. TRANSMISSION: By air-borne ascospores in wet weather/humid conditions.

Abstract A description is provided for Lophodermium conigenum. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Mainly Diploxylon (two-three needle) pines, including Pinus brutia, P. densiflora, P. montana, P. mugo, P. nigra, P. resinosa, P. sylvestris, P. tabuliformis, P. contorta, P. halepensis, P. pinea and P. radiata. Has also been recorded from Haploxylon (five needle) pines. DISEASE: Needle cast of pines. Lophodermium conigenum inhabits green needles on the tree, producing no symptoms. When a branch bearing such needles is killed by an agent other than the fungus, L. conigenum fruits seprophytically on the needles. It causes no significant damage to the tree. GEOGRAPHICAL DISTRIBUTION: Widespread in Europe, a couple of records from the USA (east coast and Michigan) where it is apparently not common, New Zealand. TRANSMISSION: By air-borne ascospores in wet weather/humid conditions.

Abstract A description is provided for Septoria cucurbitacearum. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Cucumis melo, C. sativus, Cucurbita ficifolia (=C. melanosperma), C. maxima, C. moschata, C. pepo and Bryonia dioica (=B. cretica). DISEASE: Leaf spot of cantaloupe, cucumber, melon, pumpkin, squash and vegetable marrow. The visible symptoms are circular, olive brown lesions, prominent on the upper surface of the leaves. With the progress of the disease the spots enlarge, usually reaching 3-5 mm diam., occasionally 8 mm wide and soon dry up. Older lesions tend to turn white revealing several pycnidia embedded within the tissue. GEOGRAPHICAL DISTRIBUTION: Africa (Ethiopia, Kenya, Zambia); Australasia & Oceania (Australia); Europe (Bulgaria, Denmark, France, Germany, Hungary, Italy, Portugal, Rumania, USSR); North America (USA, Delaware, Massachusetts, New Hampshire, New York, Pennsylvania, Wisconsin). TRANSMISSION: Presumably by conidia disseminated by water splash in wet weather or heavy dews.

Abstract A description is provided for Bifusella linearis. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Pinus albicaulis, P. flexilis, P. monticola, P. strobus. DISEASE: Needle blight and needle cast of white pines, tar spot needle cast, Bifusella blight. The disease apparently occurs only under moist conditions, and since its effects are usually limited to defoliation of needles two or three years old, it is not devastating. Probably infects young needles but macrosymptoms do not show up until the following spring when needles become blighted from the tip part-way to the base. The disease tends to occur principally in the lower crown (47, 2867). GEOGRAPHICAL DISTRIBUTION: North America (Canada: British Columbia, Ontario, U.S.A. : California, Colorado, Idaho, Maine, Massachusetts, Minnesota, New Hampshire, New York, North Carolina, Pennsylvania, Washington, Wisconsin). TRANSMISSION: By air-borne ascospores in wet or humid weather.

Abstract A description is provided for Phaeoseptoria vermiformis. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Triticale (Triticum × Secale), Avena (oats) and Triticum (wheat). DISEASE: Leaf spot of Triticale, wheat and oats. Lesions on leaves are irregular to elliptical, light brown to straw yellow. As infection progresses lesions enlarge to form blotches extending to the margins of leaves. GEOGRAPHICAL DISTRIBUTION: East Africa and North America (Mexico, Patzcuaro). TRANSMISSION: Presumably by conidia dispersed by water splash in wet weather or heavy dews. So far the mode of infection under natural conditions and the spread of the disease have not been investigated. It has been suggested that P. vermiformis might persist on native grasses in the field and this could serve as a source of inoculum in addition to the infected stubble or debris left over from previous years crop.

Abstract A description is provided for Phytophthora ilicis. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Ilex aquifolium, I. aquifolium f. aureo-marginata. DISEASE: Produces a severe die-back disease (leaf and twig blight) of young and mature holly plants; a facultatively necrotrophic plant pathogen. Symptoms consist of black leaf spots, defoliation, twig die-back and berry infection. Limb and trunk cankers develop inside tissues. Leaf fall begins from the lower branches and progresses upwards producing shafts or pyramids of defoliation. The disease develops well in cool, wet weather but is checked during hot, dry periods. GEOGRAPHICAL DISTRIBUTION: Europe; UK (England), Netherlands. North America; USA (OR, WA). TRANSMISSION: By sporangia borne on sporangiophores which emerge through stomata on the lower surface of leaves. Sporangia are dispersed by rain-splash or by wind and infect leaves via wounds, or twigs via leaf scars. Growth of the mycelium from twigs extends into branches. Berries are infected in late winter and spring. Oospores are formed in leaf spots and in the cortex of dead twigs. They may act as perennating structures, allowing the fungus to survive over the summer and then germinate in cooler weather.

Abstract A description is provided for Davisomycella asiatica. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Pinus sp. DISEASES: Needle cast of pines. Very little is known of the biology of this recently-described and interesting species, which has some features intermediate between Davisomycella Darker and Elytroderma Darker, but in view of the parasitic behaviour of other members of the same genus in North America, and of the strongly parasitic biology of members of the genus Elytroderma, it must be regarded as a potential pathogen of pines in south-east Asia. GEOGRAPHICAL DISTRIBUTION: Thailand. TRANSMISSION: By airborne ascospores in wet or humid conditions.

Abstract A description is provided for Lophodermium pini-excelsae. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Pinus ayacahuite, P. banksiana, P. cembra, P. excelsa, P. kesiya, P. koraiensis, P. longifolia, P. palustris, P. parviflora, P. patula, P. pentaphylla, P. peuce, P. pumila, P. strobus, P. tueda, P. wallichiana. DISEASE: Needle cast of pines. Ascocarps of this species occur predominantly on dead needles in the litter; they may also, however, occur on dead needles still attached to twigs, including twigs which have died because of suppression. The pathogenic status of this species is not clear, but it is important to distinguish it from other more strongly pathogenic pine inhabiting species of the same genus, such as L. seditiosum Minter, Staley & Millar (CMI Descriptions 568). GEOGRAPHICAL DISTRIBUTION: Asia (India: Himachal Pradesh, Jammu & Kashmir; Japan, West Pakistan), Europe (Belgium, Great Britain, Ireland), North America (Canada: Ontario). TRANSMISSION: By air-borne ascospores in wet or humid weather.
