Abstract A description is provided for Lophodermella montivaga. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Pinus attenuata, Pinus contorta. DISEASES: Needle-cast of pines. This fungus has been reported to have a 1-year life-cycle, with ascospores mature from July to October, and germinating by a short germ tube to produce an appressorium from which an infection peg was thought to penetrate the cuticle of new needles. In Colorado the first symptoms have been reported in September: the needles turned brown, and ascomata developed in them over winter. The influence of this species on individual trees and on stand growth has not been assessed. GEOGRAPHICAL DISTRIBUTION: USA (California, Colorado, Idaho, Montana, Oregon, Washington, Wyoming). TRANSMISSION: By airborne ascospores in wet or 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 Bifusella pini. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Pinus contorta, Pinus edulis, Pinus flexilis, Pinus monophylla. DISEASES: Needle cast of pines. Little is known of the biology of B. pini, but the fact that this species fruits mainly on needles more than two years old suggests that it is unlikely to be a serious pathogen. GEOGRAPHICAL DISTRIBUTION: USA (Arizona, California, Colorado, Idaho, Nevada, New Mexico, Utah). TRANSMISSION: By airborne ascospores in wet or humid conditions.

Abstract A description is provided for Lophodermella concolor. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Pinus banksiana, Pinus contorta, Pinus contorta var. murrayana. DISEASES: needle cast of pines. Lophodermella concolor is a strong pathogen with a 1-year life cycle (12, 254). New needles are infected in June and July, and turn reddish-brown about nine months later, becoming somewhat greyish brown when the ascomata start to appear in May. Infected needles are dwarfed and appear tufted. Infection is more or less even on young crowns, but on older trees the lower crown is most heavily infected, with often only the current year's needles remaining. Needle-cast occurs 12-14 months after initial infection at, or slightly before maturation of the ascomata. The disease leads often to almost entire defoliation, which may result in shoot and branch death (12, 254; Mielke, 1956). Where tree mortality due to L. concolor occurs, it is most likely to be in highly susceptible, low-vigour or stressed trees in overstocked stands (Williams, 1976). Root diseases and bark beetles may be contributory factors. Severe infection occurs in areas where fog or mist are common, and high precipitation probably increases disease incidence (Mielke, 1956). Resistant trees, which come from among the tallest and most vigourous, have been selected for inclusion in a P. contorta improvement programme, but results of any further work on resistance have not yet been reported. GEOGRAPHICAL DISTRIBUTION: Canada (Alberta, British Columbia, Ontario, Saskatchewan), USA (Colorado, Idaho, Montana, Oregon, Wyoming, Utah). TRANSMISSION: by airborne ascospores in wet or humid conditions.

Abstract A description is provided for Lophodermium indianum. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Pinus caribaea, P. glabra, P. patula, P. roxburghii, P. serotina, P. taeda; previous reports of this species on P. thunbergii are incorrect. DISEASE: Needle cast of pines. Ascocarps of this species occur predominantly on dead needles in the litter, so that at first sight it appears to be saprophytic. Almost nothing is known of its ecology, however, and since many other species of this genus inhabitating pine needles are known to exist as endophytes in apparently healthy needles before producing ascocarps, this species should be regarded as a potential pathogen until shown to be otherwise. GEOGRAPHICAL DISTRIBUTION: Asia (India: Haryana, Himachal Pradesh, Jammu & Kashmir, Madhya Pradesh, Uttar Pradesh; Pakistan: Rawalpindi). TRANSMISSION: By air-borne ascospores in wet or humid weather.

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 Pucciniastrum americanum. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Pycnia and aecia on Picea glauca (=P. canadensis), uredia and telia on Rubus idaeus (incl. R. strigosus) and R. leucodermis (raspberries). DISEASE: Needle rust of white spruce. Late leaf rust or late yellow rust of raspberry, infecting canes, leaves, petioles, calyces and fruits. GEOGRAPHICAL DISTRIBUTION: Canada and U.S.A. (widely distributed, recorded from British Columbia, Connecticut, Idaho, Illinois, Iowa, Mass., Md, Me, Montana, North Dakota, New Hamp., New Jersey, Nova Scotia, New York, Ohio, Ontario, Quebec, Vermont, Wisconsin, West Virginia). TRANSMISSION: Although the basidiospores infect Picea glauca (white spruce) (Darker, 1929) in some areas they probably play little part in the life cycle on raspberry since this rust is found on the latter host year after year in regions remote from any spruce trees (Anderson, 1956).

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.
