For New York State, Bursaphelenchus lignicolus associated with mortality of Pinus sylvestris and P. thunbergii, Phomopsis eleagni causing cankers and death of Eleagnus angustifolia, and Scirrhia acicola causing brown spot needle blight of Pinus mugo are first records of these pathogens. Monostichella robergei causing bud mortality and twig cankers on Ostrya virginiana and Endothia gyrosa causing perennial cankers on branches of Fagus sylvatica are newly reported aspects of these suscept-pathogen relationships. Canker formation by Cenangium ferruginosum on cold-injured Pinus spp., association of Fusarium oxysporum with root rot and mortality of 2-yr-old seedlings of three coniferous species, Verticicladiella procera causing root necrosis and death of Pinus strobus, and the association of V. procera with lesions on roots of P. resinosa in poorly drained soils are described.
