Abstract A description is provided for Lophodermium seditiosum. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Pinus sylvestris, P. resinosa, P. nigra, P. montezumae, P. halepensis, P. virginiana. Probably on other pines also. DISEASE: Needle cast of pines. Lophodermium seditiosum is the serious Lophodermium pathogen; it infects young needles and kills them, causing discoloration and often 'drooping' symptoms. When attack is severe the seedling or young tree may die. GEOGRAPHICAL DISTRIBUTION: Widespread in Europe, USA (notably Christmas tree growing areas including Michigan, Oregon and Washington). 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 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 Phacidium infestans. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Pinus sylvestris. DISEASE: Snow blight of pine. Ascospores released in September and October (45, 774) infect current year's needles. The depth of snow cover the following winter determines the proportion of needles showing symptoms (39, 250) which are, the following spring, a distinctive reddish-brown resulting from the destruction of chlorophyll (40, 635). Apothecia are produced on the discoloured needles, and usually complete the cycle in one year. Disease severity may be lessened by other ground vegetation, especially Calluna vulgaris and Vaccinium spp. (50, 2009). GEOGRAPHICAL DISTRIBUTION: Asia (Turkey, USSR: Siberia), Europe (Finland, France, Norway, Sweden, USSR: Estonia). TRANSMISSION: By air-borne ascospores in humid or wet weather.

Abstract A description is provided for Elytroderma torres-juanii. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Pinus halepensis, P. brutia. DISEASE: Needle blight of pines. Symptoms become visible on second year needles which in late summer assume a yellowish and later a brown colour. Discoloration starts from either end of the needle and may not extend along the whole needle. The boundary between the discoloured part and the remainder which stays green is sharply demarcated. Usually only one of the needles of the two-needle bundle is affected. Often the base of the discoloured needle next to the sheath remains green. Third-year and fourth-year needles are brown and carry ascocarps of the fungus. GEOGRAPHICAL DISTRIBUTION: Europe (Greece, Spain). TRANSMISSION: By air-borle ascospores in wet weather.
