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 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.

GEOGRAPHICAL DISTRIBUTION: So far reported only from Australia (Australian Capital Territory and Victoria). TRANSMISSION: By air-borne ascospores in wet weather/humid conditions, or even exceptionally in dry conditions (Stahl, 1966).

HOSTS: Pinus tarda, P. patula, P. palustris, P. kesiya, P. elliottii, P. caribaea. DISEASE: Needle cast of pines.

GEOGRAPHICAL DISTRIBUTION: Southern USA (and Hawaii), Central America, the Caribbean Islands, Brazil, Zambia, West Malaysia, Philippines, Australia, Fiji. TRANSMISSION: By air-borne ascospores in wet weather/humid conditions.

Abstract A description is provided for Lophodermium pinastri. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Pinus spp. ; a very wide range of Diploxylon (two-three needle) pines; has been recorded occasionally on Haploxylon (five needle) pines. DISEASE: Needle cast of pines. Lophodermium pinastri inhabits green needles on the tree producing no symptoms. When the needles senesce and fall to the litter, the fungus fruits. It causes no significant damage to the tree. GEOGRAPHICAL DISTRIBUTION: Widespread in Europe, western USA including Washington, Australia, New Zealand, Japan. TRANSMISSION: By air-borne ascospores in wet weather/humid conditions.

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 Ascochyta desmazieresii. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Lolium multiflorum and L. perenne. DISEASE: Glume and leaf spot of Italian and perennial ryegrasses. At first leaf lesions start as small purplish or chocolate-brown spots with a distinct red-purple margin. With time these enlarge, become irregular or elliptical, up to 5 mm long and distinctly visible on both sides of the leaves. Finally the centres of older lesions fade to fawn to straw yellow with numerous pycnidia immersed within the leaf tissue on both sides of the leaves but usually abundant pycnidia occur on the lower side. GEOGRAPHICAL DISTRIBUTION: Asia (Japan); Europe (Belgium, Czechoslovakia, Denmark, France, Irish Republic, UK); N. America (USA, California, Oregon, Washington); S. America (Chile, Brazil). TRANSMISSION: No specific studies reported; infection is presumably spread by air-borne conidia in wet weather or heavy dews. The fungus is also probably carried over on crop residues and debris in soil.
