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 Lophodermella cerina. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Pinus contorta, Pinus elliottii var. elliottii, Pinus ponderosa, Pinus taeda. DISEASES: Needle cast of pines. Symptoms on first-year needles have been reported to appear in November on southern pines, with the ascomata visible by late February and prominent by the end of March. Czabator et al. (1971) stated that two years' needles are affected, though it is not clear whether this means there are two sets of infected needles on a tree at the same time. All ages of pines in the southern USA have been reported to be infected, though the disease was more common in older stands, and while the infection was scattered within a stand, whole crowns of individual trees are affected. Severe and repeated attacks by L. cerina on pine species in the western USA did not cause significant mortality. GEOGRAPHICAL DISTRIBUTION: USA (Alabama, Arizona, California, Colorado, Florida, Louisiana, Mississippi, New Mexico). TRANSMISSION: By airborne ascospores in wet or humid conditions.

Abstract A description is provided for Davisomycella ponderosae. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Pinus ponderosa. DISEASES: Needle cast of pines. The fungus fruits on dead needles, or on dead portions between green parts of otherwise living needles. Trees from 1.5-9 m high have been affected, those in the higher range being affected only in the lower crown, while foliage throughout the crown of smaller trees showed symptoms. Most observations have been of the fungus fruiting on needles still attached to the tree, frequently attacking only one or two needles of a bundle. Needle bundles with attacked needles were often observed to be shed prematurely. Ascospore discharge has been observed between mid-July and mid-August, though ascomata containing spores which could germinate have been collected as late as mid-October (44, 892). GEOGRAPHICAL DISTRIBUTION: USA (Colorado). TRANSMISSION: By airborne ascospores in wet or 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 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 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.
