Branch tip dieback was noted on naturally occurring eastern red cedar (Juniperus virginianaL.) in Kittery, York County, Maine, in May1983. Black acervuli of Kabatina juniperiSchneider & v. Arx (Kabatina thujae var. juniperi sensu Morelet) were found at the base of the discolored foliage. Few branch tips were affected. Although tip blight diseases of junipers have been known in Maine for many years, this is the first report of K. juniperi in Maine. The northern limit of eastern red cedar in New England is mid-Oxford County, Maine, about 160 km north of Kittery.
